ARTERIOVENOUS FISTULA

摘要

A covered radially-expansible stent, capable of being advanced along a bodily lumen, and capable of performing as an arteriovenous shunt, and with a covering that stops short of one end of the stent at a line that slants to the longitudinal axis of the stent at an angle intermediate between 0° and 90°.
