Cook, Overland, Mo., assignors to Sherwood Medical Industries Inc. Filed June 26, 1968, Ser. No. 740,261 Int. Cl. A44b 7/00 U.S. Cl. 206-63.2 Claims ABSTRACT OF THE DISCLOSURE BACKGROUND OF THE INVENTION Field of the invention This invention relates to catheters and in particular to cardiac catheter packages.
Description of the prior art In the medical field, a substantial number of different forms of sterile containers are provided for sealingly enclosing catheters and the like. Conventionally, catheters are provided in packages requiring the elongated body portion of the catheter to be rolled or bent to be accommodated in a relatively small size container. Such bending of cardiac catheters presents a serious problem of providing in the catheter an undesired deformation thereof from the desired preselected configuration.
SUMMARY OF THE INVENTION The present invention comprehends an improved cardiac catheter package wherein the cardiac catheter is formed of a relatively stiff material. A container is provided for sealingly enclosing the catheter and preventing undesirable deformation of the catheter. The container is preferably formed of a stiff material having a configuration substantially conforming to the configuration of the catheter so that the catheter may be maintained substantially at all times in its use configuration thereby effectively precluding formation of undesirable bend or kink deformations therein.
Thus, more specifically, the invention comprehends an improved cardiac catheter package including a cardiac catheter having a stiff tubular body provided with a turned portion and a hub, and a stiff container loosely remov-ably enclosing the catheter and having a turned configuration substantially corresponding to said catheter whereby the turned body is freely received in the container in its use configuration.
Further, more specifically, the invention comprehends such a cardiac catheter package wherein the container is formed of a material permanently deforming as an incident of bending the package sufiiciently to damage the catheter thereby to provide a maintained indication of the bending.
Still further, more specifically, the invention comprehends such a cardiac catheter package wherein the container includes a cap having an undercut portion sealingly closing the container. Further, the invention comprehends the forming of the container of a transparent material such as a substantially stiff plastic. Further, the invention more specifically comprehends the provision on the con tainer of a tab portion having an aperture for use in hanging the package on a support with the hub of the catheter uppermost.
Yet further, more specifically, the invention comprehends the provision. of such a cardiac catheter package wherein the container is formed of rectilinear tubular material provided with a preselected set bend defining the turned configuration.
BRIEF DESCRIPTION OF THE DRAWINGS Other features and advantages of the invention will be apparent from the following description taken in connection with the accompanying drawing wherein:
FIG. 1 is a broken perspective view of a cardiac catheter package embodying the invention;
FIG. 2 is a fragmentary enlarged diametric section thereof taken substantially along the line 22 of FIG. 1; and
FIG. 3 is a fragmentary enlarged diametric section thereof taken substantially along the line 33 of FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT In the exemplary embodiment of the invention as disclosed in the drawing, a cardiac catheter package, generally designated 10, is shown to comprise a catheter, gen erally designated 11, having a body 12 provided at one end with a hub 13 and at the opposite end with a suitably apertured portion 14. As best seen in FIG. 1, the body 12 is provided with a turned portion 15 adjacent the apertured end 14. Illustratively, the turned portion may be turned at an angle of approximately 45 degrees.
The catheter 11 comprises a cardiac catheter formed of a relatively stiff plastic material. As discussed briefly above, it is desirable to maintain the catheter in its use configuration so that during installation of the catheter in a patient, the catheter will have the desired preselected configuration best suited for facilitated insertion. To this end, the catheter is maintained freely in a container, generally designated 16 having elongated tubular housing portion 17 and a cap 18. As shown in FIG. 1, the housing portion 17 may be provided with a turned section 19 corresponding to the turned portion 15 of the catheter.
The housing may be closed at the distal end by a suitable plug 20, as shown in FIG. 3, or, alternatively, by an internal closure formed by fusing the walls of the tubular housing 17 at its distal end.
In the illustrated embodiment, the container 16 is formed of a suitable plastic material which will permanently deform as an incident of bending of the package sufificiently to damage the catheter body thereby to provide a maintained indication of the undesirable deformation. Further, the container 16 may be formed of a transparent plastic to permit visual observation of the condition of the catheter therein.
As best seen in FIG. 2, the cap 18 comprises a cupshaped element having an undercut shoulder 21 sealingly receiving the end 22 of the container body 17. The hub 13 is fully received Within the cap 18 so that upon removal of the cap the hub may be installed in a sterile manner. The cap may be provided with a tab portion 23 having an aperture 24 adapted to permit hanging of the package 10 on a suitable support, such as a peg of a pegboard, with hub 13 uppermost and resting on the end 22 of the container body 17.
A sealing tape 25 may be provided to extend circumferentially about the inner end of the cap 18 and the tubular container body 17 to provide an indication of an opening of the package.
Thus, cardiac catheter package 10 provides an improved catheter package for facilitated sterilization and storage,
particularly well adapted for use with disposable plastic cardiac catheters. The catheter package 10 permits the catheter to be maintained in storage in the use configuration so as to eliminate undesirable deformation of the catheter such as occurs in packages requiring the catheter to be rolled or bent to be accommodated by the container. Thus, the catheter is maintained in the preselected desired configuration for facilitated manipulation and insertion.
The package provides means for facilitating selection and storage of the catheters in a readily selectible manner by means of the apertured cap permitting the catheters to be hung on pegboards for ready observation and selection. The cap 18 may be color coded for facilitated identification of the catheter size and a suitable label type tape 25 may be employed to identify further the catheter as well as to provide evidence of opening of the package.
As the catheter is disposed in the use configuration within the container, the need for tip wire stylets is eliminated while yet facilitated sterilization and storage may be provided. The use of a suitable plastic material for the container provides the desirable advantage of indicating deformations of the package which will alert the user to possible damage to the catheter. The cap configuration provides an improved means for effecting a sealed closure of the container while yet permitting facilitated manipulation of the catheter hub upon opening of the package.
While we have shown and described one embodiment of our invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as defined in the appended claims.
