Document Type and Number:
Japanese Patent JPH10500039
Kind Code:
A
Abstract:
An assembly tool for a bioprosthetic heart valve is disclosed. The tool assembles a valve having an inner and a spreadable outer stent, and includes a spreading ring with an elevated lip to hold the spread outer stent, an expander having fingers which contact the outer stent base to spread it apart, and a plunger 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 protects the tissue wrapped on the inner stent from abrasion during insertion.
