ABSTRACT:
A method for the insertion of an indwelling catheter into the subclavian vein of a patient is described herein, which includes making a first incision in the subclavian area and a second incision at a location between the sternum and the nipple. A hollow catheter having a tapered distal end is inserted into the second incision and subcutaneously tunneled to and through the first incision. A second hollow catheter, preferably a pacemaker lead introducer with a tear away sheath, is inserted through the first incision and into the subclavian vein. The indwelling catheter is passed through the hollow catheter and the tear away sheath and into the subclavian vein down to a location in the right atrium. The tear away sheath and the hollow catheter are thereafter removed and the first incision in the subclavian area is closed. A cap on the indwelling catheter exiting from the second incision is utilized to provide access to the catheter and therefore the vascular system.
