Abstract

A method of extracting a catheter assembly with an extracting device. The catheter includes a tissue ingrowth cuff that is grown into a subcutaneous location. The extracting device includes a handle and a head having an external gripping surface which is sized for inserting into a lumen of the catheter assembly for gripping an internal surface of the catheter assembly within the tissue ingrowth cuff and dislodging the cuff from surrounding tissue.

Claims

1. A method for removing a catheter assembly having a catheter stabilizing device including a tissue ingrowth cuff ingrown into a subcutaneous location by use of a device having a handle and a head having an external gripping surface, comprising the steps of:

(a) inserting the head of the device into a proximal end of a lumen extending through the catheter assembly;

(b) inserting the head further into the lumen by pushing the handle of the device until a distal end of the head is substantially longitudinally aligned with a distal end of the catheter stabilizing device; and

(c) pulling the handle, to dislodge the tissue ingrowth cuff and to remove the catheter assembly from the subcutaneous location.

2. The method according to claim 1, wherein when the external gripping surface of the head is threaded, step (b) further comprises rotating the handle while inserting the head such that the head is screwed into the lumen.
