Self-retaining single insertion double catheter assembly and method for making double catheter systems
First Claim
1. A self-retaining double catheter assembly, comprising:
- a first catheter having an exterior surface, an interior surface defining a first lumen extending longitudinally through the first catheter, a proximal portion for placement within a first subcutaneous area, and a distal portion for placement within an area to be catheterized, a distal end of the distal portion of the first catheter having a first opening therethrough;
a second catheter having an exterior surface, an interior surface defining a second lumen extending longitudinally through the second catheter, a proximaI portion for placement within a second subcutaneous area, and a distal portion for placement within an area to be catheterized, a distal end of the distal portion of the second catheter having a second opening therethrough; and
a retaining sleeve positioned around a portion of the exterior surface of the first catheter located proximal to the distal portion of the first catheter and around a portion of the exterior surface of the second catheter located proximal to the distal portion of the second catheter, wherein the portions of the exterior surfaces of the first and second catheters within the retaining sleeve are in a juxtaposed relationship and the first and second catheters are affixed within the retaining sleeve, the retaining sleeve being positioned such that when the distal portions of the first and second catheters are within an area to be catheterized and the proximal portions of the first and second catheters are within first and second subcutaneous areas, the retaining sleeve is outside the area to be catheterized and distal to first and second subcutaneous areas and the assembly is subcutaneously secured in place by the retaining sleeve.

Abstract
A self-retaining catheter assembly is provided which includes a first and second catheter and a retaining sleeve. The first and second catheters each have an exterior surface and an interior surface defining a lumen which extends longitudinally through the catheter. The first catheter has a proximal portion which is for placement within a first subcutaneous area, and the second catheter has a proximal portion which is for placement within a second subcutaneous area. The first and second catheters also each have distal portions for placement within an area to be catheterized. The retaining sleeve is positioned around a portion of the exterior surfaces of the catheters which is located proximal to the distal portions of the catheters. The portions of the exterior surfaces of the catheters within the retaining sleeve are in a juxtaposed relationship and the retaining sleeve is positioned such that when the distal portions of the first and second catheters are within the area to be catheterized, the retaining sleeve is outside the area to be catheterized and distal to the first and second subcutaneous areas, and the assembly is secured in place.

16. In a double catheter system comprising a first catheter having a first lumen extending longitudinally therethrough, and a second catheter having a second lumen extending longitudinally therethrough, a distal portion of the first catheter and a distal portion of the second catheter being configured to be placed within an area to be catheterized, a proximal portion of the first catheter being configured to be placed within a first subcutaneous area, and a proximal portion of the second catheter being configured to be placed within a second subcutaneous area, the improvement comprising:
a retaining sleeve positioned around and fixed to a portion of the first catheter and a portion of the second catheter such that the portion of the first catheter within the retaining sleeve is juxtaposed to the portion of the second catheter within the sleeve, wherein the retaining sleeve is positioned such that when the distal portions of the first and second catheters are within an area to be catheterized and the proximal portions of the first and second catheters are within first and second subcutaneous areas respectively, the retaining sleeve is located outside the area to be catheterized and distal to the first and second subcutaneous areas and the first and second catheters are subcutaneously secured in place by the retaining sleeve.
- 17. A method for making a double catheter system self-retaining, wherein the system comprises a first catheter having an exterior surface, a distal portion for insertion into an area to be catheterized, a proximal portion for placement in a first subcutaneous area, and a first lumen extending longitudinally through the first catheter, and a second catheter having an exterior surface, a distal portion for insertion into an area to be catheterized, a proximal portion for placement in a second subcutaneous area, and a second lumen extending longitudinally through the second catheter, the method comprising positioning and fixing a portion of the exterior surface of the first catheter and a portion of the exterior surface of the second catheter in a juxtaposed relationship within a retaining sleeve, wherein upon insertion of the distal portions of the first and second catheters into an area to be catheterized and placement of the proximal portions of the first and second catheters in first and second subcutaneous areas, the retaining sleeve is outside the area to be catheterized and distal to the first and second subcutaneous areas and the first and second catheters are subcutaneously secured in place by the retaining sleeve.
