Vascular access port

摘要

An implantable infusion port comprising a non planar septum, a fluid reservoir of a substantially spherical shape, inlet means to access the reservoir, and optimized outlet means from the reservoir. The present invention provides for a reservoir that precludes angular junctions between portions of the reservoir which can lead to eddies, countercurrents, and stagnation, thereby creating a more laminar and efficient flow pattern within the reservoir.

主权项

1. An improved vascular access port comprising: a) a rigid reservoir base having a partial hemispherical interior bottom surface; b) outlet means; and c) an elastomeric, needle penetrable, non-planar septum wherein the interior of the septum is partially hemispherical such that when the septum seals to the reservoir base forms a spherically shaped reservoir.
