ABSTRACT:
A split tipped catheter for cavitary entrance has a conical distal tip with a bore sized to receive an introducer needle. The conical tip wall is split on one side, permitting the wall to be opened by a spreading tool to clip the tip over the introducer. A fascial knife carries a blade with its tip protruding from the distal end of a backing plate, and a clip on the backing plate also engages the introducer needle for precisely incising the fascia in advance of the catheter.
