Definitions
- the invention relates to a textile vascular prosthesis with a circumferential pleating formed by folds and an arcuate longitudinal bend formed at least over a partial section by asymmetrical shortening of the prosthesis wall by at least one longitudinal seam extending along the partial section.
- the prosthesis according to the invention serves in particular for the replacement of the aortic arch and parts of the aorta ascending and descending aorta.
- a pleated vascular prosthesis is known from WO 03/034948 A1, in which an arch form is stabilized in that in each case two adjacent fold plies of the pleat are sewn together by transverse seams, wherein the transverse seams are approximately over half the diameter of the vascular prosthesis extend in the transverse direction. It is also known inter alia from this document to stabilize the arch shape of prostheses by inserted in the region of the arch stent.
- WO 03/051232 A1 various combinations of longitudinal and / or transverse seams are described for stabilizing the arc of vascular prostheses. The results are satisfactory. However, a simpler method of production, in particular a mechanical training of sheet stabilization, is desired.
- the invention is characterized in that the at least one longitudinal seam gathers the prosthesis wall while preserving the bellows-like structure and in the longitudinally compacted state of the pleating.
- an effective configuration of the sheet is obtained by compaction of the pleating and by the tight fitting of the individual folds of the pleat together.
- the closely spaced pleats of pleating mutually support each other, so that the attachment of a stitch, whose stitches penetrate the compacted prosthesis wall radially, is easily applied without repealing the structure of the pleating, i. the pleating is compressed in the radial direction. Due to the compaction, the seam can also be applied tightly and thus formed with tensile strength.
- the one or more threads of the at least one seam can wrap around the folds of the compacted bellows, whereby the compacted state can be maintained particularly well.
- the vascular prosthesis may be woven or knitted in the usual way.
- the pleating can be formed with self-contained rings or also helical.
- the pleat depth of the pleating is usually 0.5 to 2.5 mm, preferably 1 to 1, 5 mm.
- the arch shape of the vascular prosthesis can be preformed by thermal fixation, which has a favorable effect.
- the gathering is carried out exclusively by the at least one longitudinal seam, optionally supported by the thermal prefixing.
- the at least one longitudinal seam is formed by at least one continuous thread.
- This training allows a particularly simple production.
- the at least one seam is advantageously designed as a machine seam. It can be manufactured in particular with the aid of a long-arm sewing machine.
- the at least one seam is formed in a preferred embodiment of the invention on a compacted by compression vascular prosthesis with closely spaced pleats of pleating and holds the vascular prosthesis on the inside of the sheet in this state. On the outside of the bow, which is free of a seam, the pleating has risen to form the bow again.
- the seam can be formed einfädig or two-ply. If the seam is formed with a thread system, then a single chain stitch is suitable for this purpose. If the seam is designed as a two-thread system, then a double chain stitch is suitable. A lockstitch can also be provided for the formation of the seam.
- seams that are not secured against being threaded on their own. At least in such cases, one or both ends of the thread are secured against undesirable seaming. It may also be advantageous, especially in the case of such seams, to provide intermediate safeguards. It can then be cut to length without risk of Auffädeins bow sections.
- the securing of the thread ends and preferably also the intermediate securing between the thread ends can be made schinell. It is also possible to carry out intermediate security by hand, for example by sewing over the machine seam, for example by cross-stitching. This can be done in particular in the final inspection of the finished sheets, in which occasional stitch extensions in the region of the seam, in particular with velor threads, are closed.
- a plurality of seams may run parallel to one another in the longitudinal direction. This may be particularly advantageous for aortic bows with a large diameter.
- the distance between the parallel longitudinal seams may advantageously be in the range from 1 to 15, in particular 1 to 3 mm, wherein distances of more than 10 mm to 15 mm are generally only possible with two, outermost longitudinal seams. It is also possible to provide partial seams that complement each other. Thus, several parallel partial seams may extend in the longitudinal direction, which preferably overlap one another in the opposite direction. This can be beneficial when cutting out pieces from a larger arc. It is also possible for a plurality of part seams to be arranged one behind the other with intermediate distances in the longitudinal direction.
- the seams of the part seams are preferably secured against undesired loosening. Securing the seam ends can be done for example by seam compression, sewing, knotting or locking. Furthermore, it is advantageously possible to form a plurality of seams, in particular partial seams, with the same yarn or the same yarns without fiber interruption. The seamless intermediate pieces of the prosthesis can then be bridged by the continuous thread. All longitudinal seams are preferably arranged only in the region of the Bogenin- nenseite.
- the length of the shirred longitudinal region of the vascular prosthesis is at least 10 mm, in particular 20 to 70 mm, depending on the radian measure and / or diameter of the vascular prosthesis.
- the radian measure can be between 60 ° and 270 °, in particular between 90 ° and 180 °, and possibly also be larger.
- the clear diameter is usually 8 mm to 50 mm, with aortic arches rather in the upper area.
- the seam length of partial seams, in particular of successive and / or offset juxtaposed partial seams is generally at least 5 mm, in particular in the range from 10 to 20 mm.
- the stitch length, in particular loop length, the at least one seam is advantageously 1 to 3 mm, in particular about 2 mm.
- the at least one longitudinal seam advantageously extends between two guidelines extending in the longitudinal direction of the gland prosthesis. This makes it easy to see the guidelines on both sides of the sheet.
- the threads in the dyeing stand out clearly from the color of the textile base material of the vascular prosthesis.
- the course of the inside of the sheet can also be seen during the operation.
- the threads used are preferably multifilament threads, in particular coated threads. It can threads with the thread thickness 1/0 to
- the invention also relates to a method for producing a targeted, permanent curvature on an artificial vascular prosthesis.
- the method is characterized in that a vascular prosthesis, which optionally has a thermally prefixed arch, is axially compressed or compacted and the suture is applied at the location or locations where elastic expansion is to be prevented after which the prosthesis can be axially expanded to form the arch form.
- the invention further comprises a device for generating a targeted, permanent curvature on an artificial vascular prosthesis, comprising a chain stitch sewing machine with one arm, which comprises the sewing needle drive for a sewing needle, a coil with a thread whose end can be guided with the sewing needle , a carrier for the material to be sewn with a gripper, which concatenates the thread after passing through the material with the needle, and ei ⁇ ner feed device for the material.
- a chain stitch sewing machine with one arm which comprises the sewing needle drive for a sewing needle, a coil with a thread whose end can be guided with the sewing needle , a carrier for the material to be sewn with a gripper, which concatenates the thread after passing through the material with the needle, and ei ⁇ ner feed device for the material.
- the invention relates to an artificial vascular prosthesis, which undergoes a targeted permanent curvature by means of a sewing process.
- the compressed prosthesis is taken up by a support tube, on which the compression can also be made.
- the vascular prosthesis is applied to a support tube and compressed on this, the sewing process is particularly simple.
- the prosthetic gland is compressed very uniformly over its length.
- the support tube prevents a bending of the vascular prosthesis during the sewing process.
- the thread which is sewn into the wall of the elastic tube in the axial direction, prevents, after removal of the vessel sample. from the support tube so that the vascular prosthesis can spring back on a part of the circumference, namely in the area of the sewn area.
- the vascular prosthesis is less severely hampered. In this way, after removal from the support tube, the vascular prosthesis automatically assumes a bows whose curvature depends on the original compression and the length of the suture.
- the sewing needle preferably dips into the interior of the support tube through the vessel prosthesis and through a slot or slot made in the wall of the support tube. Then the thread can be knotted within the vascular prosthesis.
- a thread gripper is mounted in the interior of the vascular prosthesis and in particular of the support tube, which removes and concatenates the thread from the needle.
- the vascular prosthesis is turned to the left before the receiving on the support tube, so the inner surface surface to the outside and vice versa. This has the effect that the knotting made inside by the stitching method is subsequently turned outwards again. Thus, the knots do not present an obstacle to the blood circulation.
- the method thus used also allows a closer control of the sewing seam and a better possibility of processing the interlocking or knotting at the beginning and end of the seam. For example, the shortening of the end threads can be performed much more accurately.
- a support tube is present on which the vascular prosthesis can be pushed in an upset form. This ensures a secure hold for the subsequent sewing process.
- the outer diameter of the support tube corresponds in et ⁇ wa the inner diameter of the vascular prosthesis. This supports the secure stop. It is advantageous if the support tube is connected to a feed device. Then the vascular prosthesis is guided in a compressed form with a firm seat on the support tube below the needle, which leads to a uniform seam pattern.
- the invention also relates to a curved elastic vascular prosthesis which has been produced by the measures specified in one of the procedural claims.

- FIG. 3 shows a schematic representation of the region A on the inside of the aortic arch according to FIG. 1,
- FIG. 4 shows a schematic representation of the region A in another embodiment thereof
- FIG. 5 shows a schematic representation of the region A in a further embodiment
- FIG. 6 shows a schematic representation of the region A in a further embodiment
- FIG. 7 shows a perspective representation of a vessel prosthesis produced according to the invention
- FIG. 8 schematically a device according to the invention for the production of the curved vascular prosthesis.
- an aortic arch 1 which has a curved section 2 with a bend of 180 °.
- the bow section is adjoined by end pieces 3, which serve for sewing onto the remaining remnants of the natural aorta.
- the aortic arch 1 has an inner diameter of 33 mm and a pleat with seven folds 4 per cm. The pleat depth is approx. 1.5 mm.
- the folds 4 are located close to one another on the inside of the sheet 5 and continuously expand up to the outside of the sheet 6. The compacted compact state of the folds on the inside of the sheet 5 is stabilized by a single longitudinal seam 7.
- the stitches of the longitudinal seam penetrate the compacted bellows on the inner side of the sheet in the radial direction and form continuous loop-like loops, each enclose about three folds.
- the suture of the longitudinal seam 7 has a color, which stands out clearly from the white background color of the aortic arch even when soaked with blood.
- the thread of the longitudinal seam 7 is a multifilament yarn coated with silicon with a thread thickness of 3/0.
- the seam is based on a Einfadensys ⁇ system in which a thread in the single-chain stitch (Fig. 3) is sewn. In this system, a thread loop becomes radial through the prosthesis wall guided, folded in the direction of sewing and captured at the next stitch through the next loop. This forms a longitudinal chain of zu ⁇ sammen interviewden loops. On the other hand, the single thread is passed from stitch to stitch in the longitudinal direction.
- the longitudinal seam For the production of the longitudinal seam, a section of a knitted vascular prosthesis with pleating or bellows used on a support device is expediently pushed together in the longitudinal direction as far as possible until the individual folds of the bellows lie in compacted condition parallel to each other ,
- the longitudinal seam is made for example with a Langarmnähmaschine, wherein the thread penetrates the compacted folds radially. The thread ends are locked by thread compression against unwanted rising. There are also interlocks possible.
- the pleats of the pleating When the compacted bellows are pulled off the support device, the pleats of the pleating again relax except for the folds which are prevented from moving apart by the longitudinal seam on the inside of the sheet. This forms a uniform aortic arch.
- the length of the longitudinal seam is approx. 50 mm.
- FIG. 3 shows the single longitudinal seam 7 of the embodiment according to FIG. 1.
- three parallel longitudinal seams 9 are provided which are spaced apart by 1 to 2 mm.

- the partial longitudinal seams have a length of about 10 mm.
- the thread ends are secured against lifting.
- FIG. 6 shows partial longitudinal seams 11 running in a line, which each have interruptions 12 between them. The interruptions 12 have the result that the bellows are not in their area is compacted, ie after the preparation of the seam expands again.
- Such interruptions make it possible to control the size of the sheet radius or the radius of curvature.
- the partial longitudinal seams 11 and / or the interruptions 12 between them can also have different sizes by corresponding control of the seam, as a result of which archforms deviating from the circular arc shape can be formed. If it is desired for seams which have a different appearance on the one side than on the other side to have a certain side of the seam on the outside, then this can be influenced by the fact that the prosthesis may be everted before the seam is pushed together and attached is then turned back zu ⁇ .
- the aortic arch according to the invention can be impregnated in the usual way and packaged in sterile form. If the entire arc length is not used, a corresponding sheet section can be cut off before the operation.
- Aortenbögen are preferred with such seams, which have intermediate locks of the threads or have part seams with respective end locking.
- FIG. 7 shows an elastic vascular prosthesis produced according to the invention. It consists of a biocompatible, fatigue-resistant material, for example of polyethylene terephthalate. The order of magnitude of the diameters is in the two-digit millimeter range, preferably in the range of 20 to 40 mm.
- the vascular prosthesis is pushed up onto a support tube 23 and provided with at least one seam 22 extending over at least part of the wall length.
- the suture 22 is produced with a biocompatible thread 33, for example made of polyethylene terephthalate. It is sometimes advantageous to invert the vessel prosthesis 21 prior to the compressed application to the support tube 23, that is to turn the outer sides inward and vice versa. If you turn the vascular prosthesis 21 after completion, the knots are then outside and do not disturb the blood circulation.
- FIG. 8 shows, in a simplified representation, a suitable device for generating a curvature of a vascular prosthesis 21. Its design is very similar to a known chain stitch sewing machine with a lower carrier 28 with thread gripper 31 for material support and an arm 34, from which the needle movement is initiated.
- the fixed support 28 is surrounded by a support tube 23.
- a feed device 27 which is connected to the support tube 23 can perform axial movements.
- a feed drive 25 is provided for a feed drive 25 .
- the arm 34 does not differ from that of a commercial Ket ⁇ tenstichnähmaschine.
- the stroke of the sewing needle 35 is made by a sewing needle drive 24. From a coil 32 arranged in the vicinity, a thread 33 is guided to the sewing needle 35.
- the support tube 23 is provided with an elongated hole 36 in the wall in axial alignment, through which the sewing needle 35 can pass during the Näh ⁇ process.
- the length of the slot 36 corresponds to the maximum feed travel of the feed device.
- the support tube 23 serves to receive the vascular prosthesis 21. This can either be compressed manually on the support tube 23.
- one or two adjustable stops for the vascular prosthesis 21 are provided on the support tube.
- the inner diameter of the vascular prosthesis 21 corresponds approximately to the outer diameter of the support tube 23, preferably only slightly smaller. This ensures a secure hold on the support tube 23 during the sewing process.
- the compressed vessel prosthesis 21 can be provided with a seam 22 above the oblong hole 36.
- a Fa ⁇ dengreifer 31 is arranged, which receives the introduced with the sewing needle 35 thread 33 and concatenated.
- a gripper drive 26 is provided.
- the support tube 23 encloses the thread gripper 31 during the entire sewing process. The danger of grasping by hand into the rotating hook-shaped thread gripper 31 is thus excluded.
- the support tube 23 should be so designed by its rigidity that its cross-sectional shape during Nähvor ⁇ due to the radial load through the sewing needle 35 on the deferred vascular prosthesis 21 is not or only imperceptibly changed.
- the diameter of a rotating yarn gripper 31 is not more than 3 mm smaller than the inner diameter of the support tube 23. Or, conversely, the inner diameter of the support tube 23 - assuming sufficient rigidity of the support tube material - only slightly to be larger than the gripper diameter. This is advantageous because the thread grippers 31 require a minimum diameter for safe operation during gripping and linking of the thread 33.
- the scope of the method should also encompass stabilizing a pre-curvature of a vascular prosthesis already produced by thermal or chemical means.
- the method preferably includes the use of a vascular prosthesis which has a pleat. Such a vascular prosthesis can be compacted or compressed particularly uniformly.
