US 2019/0167429 A1 · 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.

Dependent claims

An expandable positioning device for repairing a heart valve, the expandable positioning device comprising:

a first expandable member having first and second axial ends and a first interior volume, the first expandable member configured to be implanted in a ventricle of a heart against an inferior surface of a native leaflet of a heart valve and expanded to reposition the native leaflet closer to an opposing native leaflet of the heart valve;
and
a second expandable member having first and second axial ends and a second interior volume, the second interior volume being fluidly sealed from the first interior volume when the expandable positioning device is implanted in the ventricle of the heart, the first axial end of the second expandable member disposed proximate the second axial end of the first expandable member, the second expandable member configured to be implanted in an atrium of the heart against a superior surface of the native leaflet and expanded to secure the positioning device on the native leaflet.
