ANCHORED MOUNTING RING

摘要

A mounting ring for a ventricular assist device or other device used in the heart includes a plate adapted to be secured to the exterior of the heart by rigid anchors such as hook, pin, or screw. When hooks are used, they can be pivotally mounted to the plate so that the hooks can rotate from retracted positions to advanced positions. A tool can be included in a mounting ring kit to move the hooks from their retracted positions to their advanced positions so that the hooks secure the plate to the heart. Preferably, all of the hooks are advanced simultaneously. The VAD or other device is then secured to the plate. The plate can be mounted to the heart in less time than required to install a traditional mounting ring by suturing to the heart.

主权项

1. A mounting ring kit comprising:
a plate having a proximal side, a distal side adapted to be placed against an exterior surface of a heart and an opening extending through the plate from the proximal side to the distal side; a plurality of passageways extending through the plate from the proximal side to the distal side; a plurality of rigid anchors disposed at least partially within the plurality of passageways; wherein the plurality of rigid anchors are movable from a retracted position towards an advanced position in which the plurality of rigid anchors project from the distal side of the plate.
