Heart Valve Delivery Device

原文（中国語）

A delivery system for a heart prosthesis includes a tubular loading member with a notch passing through its wall at a distal edge, and a prosthesis retention member positioned within the tubular loading member. The prosthesis retention member has multiple prosthesis retention areas shaped to engage prosthesis engagement portions of a heart prosthesis. The tubular loading member and the prosthesis retention member are longitudinally and rotationally movable relative to each other. The notch has multiple rotational positions that completely expose one of the prosthesis retention areas while covering the remaining areas. This delivery system allows for precise positioning and secure retention of the heart prosthesis during implantation.
