Definitions
- the field of the disclosure generally i elates to medical devices and, more particularly, relates to medical devices foi insertion into body lumens such as blood vessels or other vasculature
- a still further attribute which guide wires should have is good track- ability, meaning the ability to follow the sometimes tortuous pathways of human blood vessels.
- the ciossing guide wiie which compiises a core wire having a proximal end and a distal end, a co ⁇ ugated shaping iibbon extending fiom the distal end of the coie wiie, and a sleeve positioned ovei the co ⁇ ugated shaping ribbon and at least a poition of the core wire
- a method of directing a guide wiie to a desiied location with a body lumen which compiises introducing the guide wire into a body lumen, the guide wire having a core wire, a co ⁇ ugated shaping iibbon extending from the core wiie, and a sleeve ovei the corrugated shaping iibbon and at least a portion of the coie wiie, the guide wire teiminating in a distal tip, the corrugated shaping ribbon being defoimable between compressed and un-compiessed states; pushing the guide wire through the body lumen until the distal tip engages a site of occlusion in the body lumen, the co ⁇ ugated shaping iibbon being deformed into the compiessed state as the guide wire is further pushed; and continuing to push the guide wiie until the co ⁇ ugated shaping ribbon extends through the site of occlusion, the co ⁇ ugated
- a ciossing guide wiie which compiises a coie wiie having a pioximal end and a distal end, a spiing extending fiom the coie wiie distal end, and a sleeve positioned ovei the spiing and at least a poition of the coie wiie

- Fig 1 is a plan view of a illustrative elongate medical device constructed in accordance with the teachings of the disclosure, and shown as a guide wire;
- Fig 2 is an enlarged perspective view of the distal tip of the guide wire of Fig 1;
- Fig 3 is a longitudinal sectional view of Fig 2, taken along line 3-3 of Fig 2;
- Fig 4 is a lateral sectional view of Fig 2, taken along line 4-4 of Hg 2;
- FIG 5 is a perspective view of a guide wire approaching a lesion within a blood vessel
- Fig 6 is a perspective view similar to Fig 5 but showing the guide wire engaging a lesion within the blood vessel and compressing;
- Fig 7 is a perspective view of a guide wire advancing through the lesion of the blood vessel.
- Fig 8 is a longitudinal sectional view similar to Fig 3, but showing an alternative embodiment
- a plan view of a medical device constructed in accordance with the teachings of the disclosure is generally iefened to by reference numeral 20
- the depicted medical device is shown in the form of a guide wiie, it is to be understood that the teachings of the disclosure can be used in constructing any number of different medical devices, specifically elongated medical devices for intravascular introduction including, but not limited to, guide catheters, guide wires, balloon catheters, probes, scopes, and the like
- the guide wire 20 includes a proximal region 22 opposite a distal region 24, with the proximal region including a proximal end 26 and the distal region 24 including a distal tip 28
- the distal tip 28 is the tip of the guide wire 20 which navigates through a body lumen 30 as shown in Figs 5-7
- the proximal region 22 is the area handled by the physician or technician for pushing, turning, and otherwise manipulating the guide wire 20 as it navigates through the lumen 30
- the guide wire 20 includes a base or coie wire 32 fiom which a shaping iibbon 34 extends at the distal tip 28.
- a sleeve 36 may extend over the shaping iibbon 34 and at least a poition of the core wiie 32.
- the coie wire 32 may teiminate in a tapered end 38 and a flatten 40 from which the shaping iibbon 34 extends.
- the shaping iibbon 34 is sepaiate fiom the flatten 40 and attached thereto.
- the shaping iibbon 34 is unitaiy with the flatten 40 and the tapered end 38
- the coie wire 32, as well as the shaping iibbon 34 can be manufactured from any suitable material including, but not limited to, metals, metal alloys, oi any othei suitable mateiial.
- suitable metals and metal alloys include stainless steel, such as 304V, 304L, and 316L stainless steel; alloys including nickel-titanium alloys such as lineal elastic or supei elastic (i e., pseudoelastic) nitinol; nickel-chiomium alloys; nickel -chromium-iron alloys; cobalt alloys; tungsten or tungsten alloys; MP.35-N (having a composition of about 35% Ni, 35% Co, 20% Cr, 9 75% Mo, a maximum 1% Fe, a maximum 1% Ti, a maximum 0 25% C, a maximum 0 15% C a maximum 0.15% Mn, and a maximum 0 15% Si); hastelloy; monel 400; rnconel 825; or the like oi other suitable materials
- the core wire 32 and shaping iibbon 34 are made from diffeient materials.
- the coie wiie 32 and shaping ribbon 34 are made from diffeient materials.
- the shaping ribbon 34 includes a plurality of corrugations 42 formed by bending the shaping ribbon 34 at pivot points 44 forming legs 46 therebetween. Accordingly, when a force is directed along the longitudinal axis ⁇ of the shaping iibbon 34, the shaping iibbon 34 tends to compiess at pivot points 44 with legs 46 tending to become parallel to one anothei as shown in Fig 6 It is to be undeistood that legs 46 need not come together at angled pivot points 44, but iathei the legs 46 can be connected by flats 47 as shown in Pig 8 With such an embodiment the shaping ribbon 34 would function in much the same fashion, as that of Fig 3, compressing as it engages an occlusion and eventually expanding as it crosses through as more particularly described below
- Such constructions provide many benefits as the guide wire 20 is navigated through the body lumen 30
- the shape- ability of such a construction enables the distal tip 28 to bend and contort as the guide wire 20 navigates through the sometimes tortuous pathway of the body lumen 30
- the shaping ribbon 34 may not immediately extend through the lesion 48
- lesions or sites of occlusions 48 are typically of relatively hard material, significant force may need to be applied by the physician or technician at the proximal tip 26 to cause the guide wire 20 to extend through the lesion 48
- the shaping ribbon 34 when initial contact is made with the lesion 48 and pressure is applied by the physician, the shaping ribbon 34 will tend to compress as shown therein In so doing, the shaping ribbon 34 serves as a spring storing the energy being applied by the physician at the distal tip 28 within the legs 46 and pivot points 44 and/or flats 47 of the shaping ribbon 34 As additional force is applied by the physician at the distal region 24, eventually, the force applied by the physician and that stored within the shaping ribbon 34 will be sufficient to overcome the strength of the lesion 48, thus allowing the shaping ribbon 34 to expand and extend through the tissue of the lesion 48 This is shown best in Fig 7 [0027] Accordingly, it can be seen that not only does the shape of the ribbon 34 allow foi the necessary shape-ability in the distal tip 28 to allow the guide wire 22 to effectively navigate through the body lumen 30, but the shape also enables sufficient foice to be stoied theiein to facilitate the advancement of the guide wire 20 thiough a lesion or other site of occlusion In
- Another benefit provided by such a guide wire is its tiack-ability.
- guide wires, catheters, and other elongate medical devices are often navigated thiough the body lumen 30 along significant distances to arrive at the site of occlusion, or other desiied location Such body lumens take many twists and turns along the way and it is important that any guide wire be able to follow that path or track.
- the construction of the present disclosure with its ability to bend and contort, allows for such track- ability.
- the disclosure also allows for improved torque- ability as well, or in other words, the ability to be twisted or rotated with force, another key attribute of a guide wire.
- Figs 3 and 4 sectional views of the shaping ribbon are provided
- the lateral sectional view of Fig 4 shows that the lateral cross- sectional shape of the shaping ribbon 34 can be provided in a rectangular configuration
- the teachings of the disclosure would allow for the shaping iibbon to be manufactured from any number of other lateral cross-sectional shapes including elliptical shapes, circular shapes, oval shapes, square shapes, triangular shapes, and any other polygonal shape
- the polymer sleeve need not be provided at all In othei words, in some embodiments the guide wire could consist of the core wire 32 and the shaping ribbon 34
- the provision of the polymei sleeve 36 does allow fbi even greater cross-ability in the guide wire 20 In otdei to even further enhance the cioss-ability oi crossing performance of the guide wire 20, a coating (not shown) could be provided thereon which may be lubiicious, hydiophilic, hydrophobic, a protective, a medicated, or other type of coating
- Suitable materials for the coating are well known in the ait and may include, but not limited to, silicon, polysulfones, polyfluoiocarbons (such as TEFLON), polyolefms such as polyethylene, polypropylene, polyesters (including polyamides such as nylon), polyur ethanes, polyarylene oxides, polyvinylpyiolidones, polyvinyl
- the shaping ribbon 34 and/or the coie wire 32 need not be su ⁇ ounded by a polymei sleeve, but iathei can be surrounded by a coil spiing or the like (not shown) Such an embodiment would still have good shape-ability, cioss-ability, and track-ability as long as its dimensions are kept unifoim through its length
- the teachings of the present disclosure provide an apparatus and method for constructing and navigating a guide wire through a body lumen
- the guide wire includes a corrugated distal tip which improves the shape-ability, cioss-ability, and track-ability of the medical device .
