Abstract

Cardiac valve repair devices with coaptation members and multiple clip mechanisms and associated systems and methods are disclosed herein. A cardiac valve repair device configured in accordance with embodiments of the present technology can include, for example, an optional fixation member configured to engage tissue within a left atrium proximate to a native mitral valve, a coaptation member depending from the fixation member, and a plurality of clip mechanisms extending from a downstream portion of the coaptation member. The coaptation member can be positioned between the native leaflets and at least partially fill a space between the native leaflets. A first clip mechanism can engage a first portion of one of the native leaflets, and a second clip mechanism can engage another portion of the same native leaflet or an opposing native leaflet.
