Abstract

A composite catheter stabilizing device, a catheter assembly including such a stabilizing device and a device for removing a catheter assembly are provided. The stabilizing device includes a cuff having a first and second edge which is configured to be positioned around a catheter. The device further includes a first and second end piece. The first and second end pieces have internal surfaces defining tubular openings which extend through the end pieces. The first and second end pieces are tapered from first sides which abut the edges of the cuff to second sides and the second sides of the end pieces are configured for receiving a catheter in facing engagement. The device for removing a catheter assembly includes a handle and a head having an external gripping surface which is sized for inserting into a lumen of a catheter assembly having a tissue ingrowth cuff for gripping an internal surface of the catheter assembly within the cuff and dislodging the cuff from surrounding tissue.

Claims

1. A catheter assembly, comprising:

(a) a catheter having an external surface and at least one lumen extending therethrough; and

(b) a catheter stabilizing device, comprising

(i) a cuff having a first edge and a second edge, the cuff adhered to the external surface of the catheter;

(ii) a first end piece having an external surface and an internal surface configured to conform to the external surface of the catheter in facing engagement and being permanently affixed to the external surface of the catheter, the external surface of the first end piece being tapered from a first side abutting the first edge of the cuff to a second side; and

(iii) a second end piece having an external surface and an internal surface configured to conform to the external surface of the catheter in facing engagement and being permanently affixed to the external surface of the catheter, the external surface of the second end piece being tapered from a first side abutting the second edge of the cuff to a second side.

2. The catheter assembly according to claim 1, wherein the cuff is adhered to the external surface of the catheter by an adhesive.

3. The catheter assembly according to claim 1, wherein the first and second end pieces comprise a heat moldable material and are molded onto the external surface
