Vascular access system for extracorporeal treatment of blood
First Claim
1. An implantable vascular access device including a port comprising:
- (a) a biocompatible housing having an internal open-faced chamber extending along a reference axis and defined by a sidewall forming a lateral boundary and being concave in the direction of said axis, and a bottom wall;
(b) a septum affixed to said housing and spanning the periphery of the open face of said chamber,said septum including a biocompatible, self-resealing, penetrable material; and
(c) a cannula attached at a first end thereof to said housing and extending laterally therefrom, and having a second end thereof adapted to receive a catheter,said cannula further having internal walls defining a channel extending from said first end, along a channel axis from a point on said lateral boundary of, and in communication with, said chamber, to said second end, wherein the transition between said lateral boundary of said chamber and said internal walls of said canula is smooth.

Abstract
Disclosed are implantable, vascular access ports and vascular access systems including such ports. These ports include a biocompatible housing having at least one internal open-faced chamber extending along a reference axis, and defined by a concave sidewall and a bottom wall. The concave sidewall is concave in the direction of the axis and forms a lateral sidewall for the chamber. The port further includes a septum of biocompatible, self-resealing, penetrable material affixed to the housing and spanning the periphery of the open face of the chamber. A cannula is attached at a first end to the housing and extends laterally from that end. Its second end is adapted to receive a catheter. The cannula further includes internal walls defining a channel extending from the first end, along a channel axis from a point on the lateral boundary of, and in communication with, the chamber to the second end.
