Abstract
A system for implanting a heart valve includes a radially self-expandable tubular body having a preformed groove disposed at an outer surface of the tubular body, and a valve disposed within the tubular body. The preformed groove extends at least partially around the tubular body, and has a circumferential opening facing radially outward. A trapping member is configured to be disposed within the preformed groove on the outer surface of the tubular body and form at least a partial loop around the tubular body. The circumferential opening of the preformed groove is relatively larger when an outflow end of the tubular body has been deployed from a catheter and an inflow end of the tubular body is disposed within the catheter, and the circumferential opening of the preformed groove is relatively smaller when both the outflow end and the inflow end are fully deployed from the catheter.
