Patent ID: 7794422

Claim:
A catheter port assembly comprising: a catheter having a proximal catheter portion concluding in a proximal catheter end and being adapted for implantation into vasculature of a patient and subcutaneous tunneling of the proximal portion; and a port body having an open distal end, an open proximal port end and a longitudinal channel extending therethrough between the open distal end and the open proximal port end, the open proximal port end being adapted to be mechanically releasably coupled to an extracorporeal device; the port body further comprising a valve enclosed therein and disposed along the longitudinal channel; wherein the valve is adapted to restrict flow in at least one direction; wherein the distal end is adapted to be connected to the proximal end of the subcutaneously tunneled proximal catheter portion; wherein the distal end is further adapted to be at least partially inserted into an exit of the subcutaneous tunnel of the patient after being connected to the catheter; and wherein the proximal port end is externally exposed at the exit to be coupled to the extracorporeal device.
