Abstract

A device for removing a catheter assembly having a catheter stabilizing device from a subcutaneous location in a patient is disclosed. The device includes a handle having a proximal end and a distal end. A head is attached to the distal end of the handle. The head has an external gripping surface. The head is sized for insertion 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 having a catheter stabilizing device including a tissue ingrowth cuff;

a device for removing the catheter stabilizing device from a subcutaneous location comprising;

(a) a handle having a proximal end, a distal end;

(b) a head attached to the distal end of the handle, the head having an external gripping surface, wherein the head is sized for inserting into a lumen of the catheter assembly having the tissue ingrowth cuff for gripping an internal surface of the catheter assembly within the cuff and dislodging the cuff from surrounding tissue.

2. The device according to claim 1, wherein the head further comprises a tapered end for more easily inserting the head into the lumen of the catheter assembly.

3. The device according to claim 1, wherein the handle and the head comprise a material selected from the group consisting of metal and plastic.

4. The device according to claim 1, wherein the external gripping surface of the head is threaded for screwing into the lumen of the catheter.

5. The device according to claim 1, wherein the head has a cross-sectional diameter which is greater than a cross-sectional diameter of the handle, wherein the diameters are measured in a plane perpendicular to the longitudinal axis of the device.
