Patent ID: 7473240

Claim:
A kit of parts adapted to establishing percutaneous vascular access to a patient during a fluid transfer procedure, said kit comprising: a valve port system for providing vascular access in a patient through a subcutaneous fluid flow conduit during a dialysis procedure; an extractable engagement member for percutaneous patient entry defined by a tubular body having a proximal end, a distal end and a tubular lumen therebetween, said distal end having a tapered bevel defining an opening thereat and a tapered protrusion proximate thereto defined upon an exterior surface of said tubular body, said protrusion having a generally parabolic profile; and a port member having a housing with a generally cylindrical valve rotatably positioned therein, said rotatable valve having an open end, a closed end and an orifice proximate said closed end, said body being rotatable about its central axis between an open position and a closed position; said valve further having a longitudinal groove defined along an interior surface thereof capable of being in registry with said engagement member protrusion, said groove coincident with said protrusion for intussusception of said protrusion therein such that rotation of said engagement member effects rotation of said valve between said open and closed positions.
