1. A subcutaneous vascular access device designed for repeated access to a native body vessel comprising:
a lumen and a housing, said lumen extending between said housing located at a lumen proximal end and a lumen distal end configured to be attached to an anastomosis junction with a blood vessel, said anastomosis junction being located at a the lumen distal end, wherein said lumen is configured to be in fluid communication with the native body vessel and said housing,
wherein fluid flow through said lumen is selectively sealed by a clamp,
wherein said housing comprises at least one funnel shaped needle receptor, a hollow spherical chamber, and at least one clamp actuator that is mechanically linked to said clamp and is arranged to selectively actuate said clamp,
wherein said at least one funnel shaped needle receptor is selectively in fluid communication with said hollow spherical chamber and said at least one funnel shaped needle receptor is arranged coaxially on an axis that intersects said hollow spherical chamber at a point that is tangential to said hollow spherical chamber such that said tangential intersection is arranged to provide a non-stagnating flow path, and further,
wherein said lumen is in fluid communication with said hollow spherical chamber.
