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.
