A port ( 100 ) for a catheter assembly ( 200 ), including a body ( 102 ) and a cover ( 150 ) and having a distal discharge port ( 116 ) for connection to an implanted catheter assembly. Within the body is a longitudinal U-shaped channel ( 120 ) extending to a proximal body wall ( 104 ) from the distal body wall ( 106 ) along a longitudinal axis parallel to the axis of the discharge port ( 116 ). The channel has a rounded bottom ( 122 ) and is also rounded at the channel ends ( 126,124 ) at the distal and proximal body walls. The cover ( 150 ) provides for penetration by a syringe needle and seals upon needle withdrawal, with the cover having an inside surface ( 152 ) that is concave and rounded between the distal and proximal ends and also longitudinally, being generally smoothed into the channel sides and ends. The port has no inner sharp edges or corners and eliminates blood clotting and unwanted growth sites.
