Abstract

A venous access port (100,100A) having a port body (102), a septum (104), a chamber (112,112A) and a discharge port (108) with a passageway (110) extending therethrough outwardly from the chamber. The central region of the chamber (112,112A) is elevated with respect to the periphery of the chamber floor adjacent the chamber side wall and may be convex or conical, with the chamber floor periphery defining a vortex flow path (116,116A).

Claims

1. A venous access port comprising:

a port body having a discharge port, and a needle-penetrable septum affixed thereto, together defining a chamber therebetween in fluid communication with a passageway through the discharge port,

the chamber having a chamber side wall and a chamber floor wherein the central region of the chamber floor is elevated with respect to the peripheral region of the chamber floor.

2. The venous access port of claim 1 wherein the chamber floor is convex in the central region.

3. The venous access port of claim 1 wherein the chamber floor is conical upwardly to an apex and has relatively flat sloping side surfaces extending to the chamber floor periphery.

4. The venous access port of claim 3 wherein the periphery of the chamber floor is radiused to join the chamber side wall.

5. The venous access port of claim 1 wherein the chamber floor has no level portion of substantial size.
