ARTERIAL AND VENOUS ANCHOR DEVICES FORMING AN ANASTOMOTIC CONNECTOR AND SYSTEM FOR DELIVERY

摘要

An arterial anchor device and a venous anchor device operably coupled by graft material to form an anastomotic convector is provided. The arterial anchor device comprises a generally tubular main body including a distal end and a proximal end, the distal end defining a plurality of flanges integrally formed with the tubular main body and being movable from a first loaded position to a second expanded position. The venous anchor device includes a tubular main body having a metal frame structure and including a distal end and a proximal end, the distal end including a plurality of barbs thereon wherein said distal end has an outer diameter greater than the proximal end. The arterial anchor device and venous devices are fluidly connected by a graft to form an anastomotic connector.

主权项

1. An arterial anchor device for use in an anastomotic connector comprising:
a generally tubular main body comprising a metal frame-like structure comprising a plurality of struts and connectors and including a distal end, a mid-portion, and a proximal end; and a plurality of flanges integrally formed with the main body at a distal end thereof, said flanges movable between a loaded position and an expanded position, wherein said distal end comprises a variable cutting pattern such that the struts and connectors at the distal end are closer together than the struts and connectors at the mid-portion and proximal end.
