Abstract

A package or container for a catheter having a catheter tube with a proximal end provided with a catheter outlet and a distal opening at a distal end thereof. A gel receptacle is provided with a cavity for holding an amount of a lubricating agent, and the catheter tube extends therethrough. The gel receptacle is configured such that as the catheter is withdrawn from a stored position therein, a leading tip of the catheter is immersed in the lubricating agent, thus automatically coating the leading tip. The gel receptacle may be held within a rigid body or may be a standalone item packaged in a sterile bag solely with the catheter. A side wall of the gel receptacle is deformable so that as the catheter is withdrawn proximally the side wall is collapsed inward to displace the lubricating agent gel and coat an exterior surface of the catheter tube.

Claims

1. A catheter package comprising:

an outer container defining an inner space;

a catheter received in the inner space of the outer container, 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,

a gel receptacle provided in the inner space of the outer container, the gel receptacle defining a cavity therein containing a lubricating agent gel, the gel receptacle having a distal opening at a distal end with an inner diameter corresponding to a catheter diameter, and a proximal opening at a proximal end with an inner diameter larger than the catheter tube, wherein in a stored position the catheter extends through the gel receptacle with the distal tip of the catheter tube positioned distal to the gel receptacle and the catheter outlet positioned proximal to the gel receptacle, and wherein a side wall of the gel receptacle is made of a deformable material and configured to collapse inward on the catheter tube; and

wherein a side wall of the gel receptacle is molded to have a collapsed relaxed state such that withdrawing the catheter proximally from its stored position in the gel receptacle permits the side wall to collapse inward and displaces the lubricating agent gel in the receptacle and coats an exterior surface of the catheter tube with the lubricating agent gel.

2. The catheter package of claim 1, wherein the deformable material is silicone rubber.

3. The catheter package of claim 1, wherein the outer container has a rigid main body and the gel receptacle is held in an inner space of the main body, wherein the main body has diametrically-opposed apertures that expose the side wall of the gel receptacle such that a user may manually collapse the side wall inward.

4. The catheter package of claim 1, wherein the side wall has at least one inward projection which extends inward into contact with the catheter tube.

5. The catheter package of claim 4, wherein there are at least two opposed inward projections which extend inward into contact with opposite side of the catheter tube and hold the side wall away from the catheter tube to create a volume within the gel receptacle for receiving the lubricating agent gel.

6. The catheter package of claim 5, wherein the side wall and inward projections extend substantially the entire length of the gel receptacle.

7. The catheter package of claim 5, wherein the side wall and inward projections extend along less than half of the length of the gel receptacle.

8. The catheter package of claim 5, wherein the side wall and inward projections are formed adjacent the distal end of the gel receptacle and the side wall comprises a series of circumferentially spaced concave portions and the inward projections comprise radial fins attached thereto.

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

10. The catheter package of claim 1, wherein the outer container comprises a flexible, sterile bag and the catheter and gel receptacle are the only items within the bag.

11. A catheter package comprising:

an outer container defining an inner space;

a catheter received in the inner space of the outer container, 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,

a gel receptacle provided in the inner space of the outer container, the gel receptacle defining a cavity therein containing a lubricating agent gel, the gel receptacle having a distal opening at a distal end with an inner diameter corresponding to a catheter diameter, and a proximal opening at a proximal end with an inner diameter larger than the catheter tube, wherein in a stored position the catheter extends through the gel receptacle with the distal tip of the catheter tube positioned distal to the gel receptacle and the catheter outlet positioned proximal to the gel receptacle, and wherein a side wall of the gel receptacle is made of a deformable material and molded to have a collapsed relaxed state such that such that withdrawal of the catheter proximally from its stored position permits the side wall to collapse inward and displace the lubricating agent gel in the receptacle onto an exterior surface of the catheter tube, and wherein there are at least two opposed inward projections which extend inward into contact with opposite side of the catheter tube and hold the side wall away from the catheter tube to create a volume within the gel receptacle for receiving the lubricating agent gel.

12. The catheter package of claim 11, wherein the deformable material is silicone rubber.

13. The catheter package of claim 11, wherein the outer container has a rigid main body and the gel receptacle is held in an inner space of the main body.

14. The catheter package of claim 11, wherein the gel receptacle has a cylindrical proximal end and a cylindrical distal end flanking an indented section formed by opposed flat walls that extend along a proximal-to-distal axis substantially the whole length of the gel receptacle.

15. The catheter package of claim 14, wherein the inward projections extend inward from the opposed flat walls and projections from one wall are offset from projections from the opposed wall.

16. The catheter package of claim 11, wherein the side wall and inward projections extend substantially the entire length of the gel receptacle.

17. The catheter package of claim 11, wherein the side wall and inward projections extend along less than half of the length of the gel receptacle.

18. The catheter package of claim 11, wherein the side wall and inward projections are formed adjacent the distal end of the gel receptacle and the side wall comprises a series of circumferentially spaced concave portions and the inward projections comprise radial fins attached thereto.

19. The catheter package of claim 11, wherein the outer container comprises a flexible, sterile bag and the catheter and gel receptacle are the only items within the bag.
