Abstract

A rigid package or container for a catheter having catheter tube with a distal end and a proximal end, the proximal end being provided with a catheter outlet which may be used as a funnel or a connector. A main body is provided for holding the catheter, and a cap closes off the main body. A gel receptacle is positioned inside the main body, the gel receptacle being provided with a cavity for holding an amount of a lubricating agent. The gel receptacle includes a distal opening at a distal end thereof, and a proximal opening at a proximal end thereof, with the catheter tube extending therethrough. The gel receptacle is configured such that as the catheter is withdrawn therethrough a leading tip of the catheter is displaced so as to be immersed in the lubricating agent, thus automatically coating the leading tip.

Claims

1. A catheter package comprising:

a) a rigid main body defining an inner space, and a cap provided at a proximal end of the main body which closes off a proximal end of the inner space;

b) a catheter received in the annular cavity of the main body, the catheter including a flexible catheter tube having a distal tip and at least one discharge opening proximate the distal tip, and a catheter outlet provided at a proximal end of the catheter tube,

c) a gel receptacle held in the inner space of the main body, the gel receptacle defining a cavity therein containing a lubricating agent, the gel receptacle having a distal opening at a distal end thereof with an inner diameter approximately the same as an outer diameter of the catheter tube, and a proximal opening at a proximal end thereof with an inner diameter greater than the outer diameter of the catheter tube; and

wherein the catheter is stored in the inner space of the main body with the distal tip of the catheter tube positioned distal to the gel receptacle and the catheter outlet positioned proximal to the gel receptacle such that withdrawing the catheter proximally from the main body coats an exterior surface of the catheter tube with the lubricating agent, and wherein the gel receptacle is configured such that the distal tip of the catheter tube displaces laterally from a straight line therethrough when it clears the distal opening to enhance lubricating agent coating of the distal tip.

2. The catheter package of claim 1, wherein the gel receptacle is generally tubular and the distal and proximal openings are offset from each other relative to a longitudinal axis through the gel receptacle so that the catheter must form a curve through the gel receptacle.

3. The catheter package of claim 2, wherein the distal opening is formed in a side wall of the gel receptacle and the proximal opening is formed in an end wall of the gel receptacle.

4. The catheter package of claim 2, wherein both the distal and proximal openings are formed in end walls of the gel receptacle.

5. The catheter package of claim 4, wherein both the distal and proximal openings are positioned at opposite lateral sides of the longitudinal axis.

6. The catheter package of claim 1, wherein the gel receptacle is shaped so as to form an inward bulge on one side which extends into a straight line path for the catheter tube extending between the distal and proximal openings so as to deform the catheter tube through the gel receptacle.

7. The catheter package of claim 6, wherein the gel receptacle is generally tubular.

8. The catheter package of claim 6, wherein the gel receptacle is serpentine shaped.

9. The catheter package of claim 6, wherein both the distal and proximal openings are centered in end walls of the gel receptacle.

10. The catheter package of claim 1, wherein the gel receptacle includes a spring finger which extends into a straight line path for the catheter tube extending between the distal and proximal openings so as to bias and deform the catheter tube through the gel receptacle.

11. A method of lubricating a catheter distal tip stored in a rigid package, comprising:

a) providing a catheter package comprising;

i. a rigid main body defining an inner space, and a cap provided at a proximal end of the main body which closes off a proximal end of the inner space, a catheter being received in the annular cavity of the main body, the catheter including a flexible catheter tube having a distal tip and at least one discharge opening proximate the distal tip, and a catheter outlet provided at a proximal end of the catheter tube, and a gel receptacle held in the inner space of the main body, the gel receptacle defining a cavity therein containing a lubricating agent, the gel receptacle having a distal opening at a distal end thereof with an inner diameter approximately the same as an outer diameter of the catheter tube, and a proximal opening at a proximal end thereof with an inner diameter greater than the outer diameter of the catheter tube wherein the catheter is stored in the inner space of the main body with the distal tip of the catheter tube positioned distal to the gel receptacle and the catheter outlet positioned proximal to the gel receptacle such that withdrawing the catheter proximally from the main body coats an exterior surface of the catheter tube with the lubricating agent; and

b) withdrawing the catheter from the inner space of the main body such that the distal tip of the catheter tube automatically displaces laterally within the gel receptacle to enhance lubricating agent coating of the distal tip.

12. The method of claim 11, and wherein the gel receptacle is configured such that the distal tip of the catheter tube displaces laterally from a straight line therethrough when it clears the distal opening.

13. The method of claim 11, wherein the gel receptacle is generally tubular and the distal and proximal openings are offset from each other relative to a longitudinal axis through the gel receptacle so that the catheter must form a curve through the gel receptacle.

14. The method of claim 12, wherein the distal opening is formed in a side wall of the gel receptacle and the proximal opening is formed in an end wall of the gel receptacle.

15. The method of claim 12, wherein both the distal and proximal openings are formed in end walls of the gel receptacle.

16. The method of claim 15, wherein both the distal and proximal openings are positioned at opposite lateral sides of the longitudinal axis.

17. The method of claim 11, wherein the gel receptacle is shaped so as to form an inward bulge on one side which extends into a straight line path for the catheter tube extending between the distal and proximal openings so as to deform the catheter tube through the gel receptacle.

18. The method of claim 17, wherein the gel receptacle is generally tubular.

19. The method of claim 17, wherein the gel receptacle is serpentine shaped.

20. The method of claim 11, wherein the gel receptacle includes a spring finger which extends into a straight line path for the catheter tube extending between the distal and proximal openings so as to bias and deform the catheter tube through the gel receptacle.
