Abstract

An applicator for gripping a urinary catheter. The applicator includes a body having a proximal end, a distal end and a lumen extending therethrough for receiving a catheter. The body includes at least one projection disposed within the lumen which contacts the catheter shaft to resist movement of the body along the catheter shaft.

First claim

The invention claimed is:

1. A urinary catheter assembly, comprising:
a catheter package having a cavity;
a urinary catheter disposed within the cavity, the catheter including a catheter shaft having a proximal insertion end portion and a distal end portion and a drainage member associated with the distal end portion of the catheter shaft;
an applicator for gripping the catheter located within the cavity, the applicator including
a body having a proximal end and a distal end;
a lumen extending through the proximal and distal ends of the body, the lumen having a proximal end opening and a distal end opening, the shaft of the catheter received within and extending through the lumen, the body being located distal of the proximal insertion end portion of the catheter, wherein a proximal end of the drainage member is located within the distal end of the body to releaseably attach the applicator to the drainage member, and the body being movable proximally and distally along the catheter; and
a plurality of projections disposed within the lumen and in constant contact with the catheter shaft as the body is moved proximally and distally along the catheter and the plurality of projections resisting free movement of the body along the catheter shaft.

2. The assembly of claim 1 wherein at least a portion of the body is elastically deformable and deforms to contact the catheter shaft for grasping the catheter.

3. The assembly of claim 1 wherein the plurality of projections comprise petals.

4. The assembly of claim 3 wherein the petals are separated by slits.

5. The assembly of claim 1 wherein the plurality of projections have a generally rounded shape.

6. The assembly of claim 1 wherein the plurality of projections is located in the proximal end opening.

7. The assembly of claim 1 wherein the plurality of projections is located in the distal end opening.

8. The assembly of claim 1 wherein the plurality of projections is located in both the proximal end opening and the distal end opening.

9. The assembly of claim 1 wherein the plurality of projections is located distal of the proximal end opening and proximal of the distal end opening.

10. The assembly of claim 1 wherein the body is configured to be releasably attached to a drainage member attached to the catheter shaft.

11. The assembly of claim 10 wherein the distal end opening is configured to receive the proximal end of the drainage member.

12. The assembly of claim 11 wherein the lumen has a first diameter and the distal opening has a second diameter that is larger than the first diameter.

13. The assembly of claim 1 wherein the plurality of projections extend substantially the length of the lumen.

14. The assembly of claim 1 wherein the body includes a gripping surface.

15. The assembly of claim 1 wherein the plurality of projections are in constant contact with the catheter shaft when the catheter shaft is received within the lumen.
