Abstract
An anti-suture looping device for prosthetic polycuspid heart valves is provided. The device comprises a frame or body portion that is attached to the heart valve assembly and a vaned insert portion that can project beyond the cusps of the heart valve. The insert portion can slide within the body portion between a retracted position where the vanes do not project beyond the free ends of the cusps of the valve and a forward position where the vanes pass between the cusps of the valve, extend beyond, and protect the cusps from interference or damage by any suture loops that may catch on the cusps when the heart valve assembly is secured into place.
