## Abstract

A device for retaining a supra pubic catheter having a moveable retainer axially moveable along the catheter.

## Claims

### Claim 1

A method of inserting a supra pubic catheter, the method comprising the steps of:
providing the supra pubic catheter having a proximal end and a distal end, the distal end having an inflatable balloon, and the proximal end having a retainer that frictionally engages the catheter;
surgically creating a stomal tunnel in a pelvic wall through to the bladder;
inserting the distal end of the catheter having the balloon through the stomal tunnel and into the bladder;
inflating the balloon such that the distal end of the catheter is maintained in the bladder; and
sliding the retainer along the catheter towards the pelvic wall such that the balloon is secured against the bladder to prevent leakage within the stomal tunnel and movement of the balloon relative to the bladder.

### Claim 2 (depends on 1)

The method of claim 1, wherein the retainer includes a hole for co-axially receiving the catheter.

### Claim 3 (depends on 2)

The method of claim 2, wherein the retainer includes a plurality of internal rings in the hole such that the rings aid in the retainer frictionally engaging the catheter.

### Claim 4 (depends on 1)

The method of claim 1, wherein the retainer includes a wall adapted to abut the pelvic wall.
