发明名称 ASSEMBLY TOOLING FOR AN AUTOLOGOUS TISSUE HEART VALVE
摘要 <p>An assembly tool (10) for a bioprosthetic heart valve is disclosed. The tool assembles a valve having an inner and a spreadable outer stent (5), and includes a spreading ring (20) with an elevated lip (26) to hold the spread outer stent, an expander having fingers (46) which contact the outer stent base (6) to spread it apart, and a plunger (24) to spread the fingers of the outer stent. An assembly mandrel having indexing rails allows the insertion of the inner stent into the spread outer stent while maintaining the correct rotational positioning of both stents. A shedding cap (56) protects the tissue wrapped on the inner stent from abrasion during insertion.</p>
