Abstract

Packaging for a medical catheter has a mounting card on which the catheter is placed and a cover sheet for covering the catheter to form a pouch or envelope. Discrete portions of the cover sheet are affixed to the mounting card on opposing sides of the catheter body, to restrict movement of the catheter from a desired shape.

Claims

1. Packaging for a medical catheter, comprising:

a mounting card on which a medical catheter is disposed;

a cover sheet which forms a sealed envelope enclosing said medical catheter; and

a plurality of discrete retainers, each retainer being defined by a portion of said cover sheet which is fastened to said mounting card, for restricting movement of said catheter from a desired shape.

2. Packaging for a medical catheter, comprising:

a mounting card on which a medical catheter is disposed;

a first and second outer sheet which are sealed together along their respective perimeters to form an envelope enclosing said mounting card and catheter; and

a plurality of discrete retainers, each retainer being defined by a portion of said cover sheet which is fastened to said mounting card, for restricting movement of said catheter from a desired shape.

3. The packaging for a medical catheter as set forth in claim 2, wherein said retainers are formed by a melted portion of said first outer sheet which is affixed to said mounting card.

4. The packaging for a medical catheter as set forth in claim 2, wherein said retainers are laterally spaced apart, out of direct contact with said catheter.

5. The packaging for a medical catheter as set forth in claim 2, wherein said catheter is directly contacted only by said first outer sheet and a first surface of said mounting card.

6. The packaging for a medical catheter as set forth in claim 2, wherein a distal tip portion of said medical catheter is formed in a preselected curved shape, said retainers being disposed along a relatively straight body portion of said medical catheter, said retainers being longitudinally spaced apart from each other, such that said retainers impose reduced bending stress on said tip portion of said medical catheter when said medical catheter is longitudinally pulled from said packaging.

7. The packaging for a medical catheter as set forth in claim 2, wherein said retainers are disposed in relation to said mounting card in opposing pairs on opposite sides of said catheter body.

8. The packaging for a medical catheter as set forth in claim 2, wherein one of said outer sheets is formed of a porous material.

9. The packaging for a medical catheter as set forth in claim 2, further comprising a flexible tip tray disposed within said envelope and having a flexible groove for receiving and releasably securing a curved tip portion of said medical catheter, for protecting said curved tip portion and for maintaining said tip portion in a preselected curved shape, while allowing said catheter to be longitudinally pulled from said tip tray.

10. The packaging for a medical catheter as set forth in claim 2, wherein said mounting card further comprises a hub recess opening for partially receiving said hub.

11. The packaging for a medical catheter as set forth in claim 2, wherein said mounting card is formed without any perforation in proximity to said retainers.

12. The packaging for a medical catheter as set forth in claim 2, wherein said mounting card further comprises a pair of alignment openings for removably receiving an alignment member.

13. The packaging for a medical catheter as set forth in claim 2, further comprising a flexible tip tray having a flexible groove for receiving and releasably securing a curved tip portion of said medical catheter.

14. A method of assembling packaging for a medical catheter, comprising the steps of:

a) placing a catheter onto a mounting card;

b) applying a first and second outer sheet about said catheter and mounting card;

c) sealing said first and second outer sheet together along their respective perimeters, thereby forming an envelope which encloses said mounting card and catheter; and

d) fastening discrete portions of said first outer sheet to said mounting card to form a plurality of retainer elements for restricting movement of the catheter from a desired shape.

15. The method of assembling packaging for a medical catheter as set forth in claim 14, in which said step (d) is performed by applying localized heat and pressure to said first outer sheet to partially melt a portion of said first outer sheet to form said retainer elements.

16. The method of assembling packaging for a medical catheter as set forth in claim 14, in which said step (a) further comprises the additional step of aligning said mounting card on an operating surface by inserting a pair of aligning pins through a corresponding pair of alignment holes formed in said mounting card, and aligning a portion of said catheter between said aligning pins.

17. The method of assembling packaging for a medical catheter as set forth in claim 16, further comprising the additional step immediately preceding said step b) of aligning said catheter in a desired position relative to said mounting card by dragging an alignment fork along a portion of said mounting card.
