Abstract

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.

Claims

1. A port for transmitting a fluid to a conduit, comprising:

an elongated body having;

a proximal end;

a distal end having a discharge port extending exterior from the body for connection to a conduit; and

a channel extending between the proximal and distal ends, wherein the channel is in fluid communication with the exterior of the body through the discharge port;

and

a cover fixedly connected to the body and extending over the channel such that the channel is wholly contained within the body and the cover,

the body and the cover having inside surfaces being generally rounded and smooth and free of sharp edges and corners.

2. The port according to claim 1, wherein the body is constructed from a metal.

3. The port according to claim 1, wherein the cover is constructed from a polymer and is self-sealing to permit needle insertion and to seal upon needle withdrawal.

4. The port according to claim 1, wherein the cover further comprises at least one support strut extending therethrough.

5. The port according to claim 1, wherein the channel comprises a generally concave shape.

6. The port according to claim 1, wherein the cover comprises a generally convex shape.

7. The port according to claim 1, wherein the body is adapted to be secured to a patient.
