Abstract
A prosthetic heart valve device includes a valve support, a prosthetic valve assembly disposed within the valve support, and an anchoring member. The anchoring member includes a base attached to a first region of the valve support, a plurality of arm units projecting laterally outward from the base and inclined in a direction away from the first region in a deployed state, and a fixation structure extending from the arm units. Each arm unit includes a first portion coupled to the base and a second portion coupled to the fixation structure. The fixation structure includes a plurality of struts that define an annular engagement surface configured to press outwardly against a native annulus of a native heart valve. The first portion of each arm unit has a first flexibility greater that a second flexibility of the second portion of each arm unit.
