Expandable heart valve coaptation device

Abstract:

In one embodiment, an expandable positioning device for improving the coaptation of heart valve leaflets is provided. The expandable positioning device can include one or more expandable members. A first expandable member extends below a leaflet in order to reposition the leaflet to improve coaptation with another leaflet. A second expandable member extends above a leaflet in order to secure the expandable delivery device at the implantation site. The expandable positioning device can include a neck that is inserted through the leaflet on which the device is implanted. The expandable positioning device can include a coupling member to releasably couple the device to a delivery device. One or more sealing members can be included in the expandable positioning device to maintain a desired level of expansion of the one or more expandable members.
