Device for covering hole in heart wall has retention and/or guide part holding membrane body in elongate shape during insertion before release to provide covering surface for hole in heart wall

摘要

The device has an elongate retention and/or guide part (5) for supporting a soft membrane body (6), secured to the elongate retention and/or guide part at 2 spaced fixing points (7,8), a resetting force acting on the membrane body so that it shortens to provide a covering surface for a hole in the heart wall, upon release of one of the fixing points. A flexible elastic reinforcement (9), e.g. a wire, can be provided around the peripheral edge of the membrane body.
