Abstract

Official abstract text for this publication.

A graft is used to interconnect two vessels, such as an artery and a vein for hemodialysis. The graft includes a body having first and second ends, and a wall to define a passageway formed in the body. The wall includes a plurality of tubular layers, such as a first layer and one or more second layers disposed radially inward relative to the first layer. Each second layer has first and second ends that can be enclosable. The second layer is removable from the graft body from within the passageway of the graft body after clot formation. A grasper can be used to attach with at least one of the ends of the second layer. In response to withdrawal of the grasper, the corresponding end of the second layer gathers radially inward away from a layer adjacent to the second layer.
