Valve positioning device
First Claim
1. A prosthetic heart valve comprising:
- a valve assembly;
an expandable annular frame coupled to the valve assembly, the frame configured to expand within a native valve annulus, the frame including at least three commissural posts, each commissural post being arranged around a central longitudinal axis of the prosthetic heart valve and being configured to align with a native commissure of a native heart valve; and
at least three control arms disposed circumferentially about the frame when the frame is in an expanded configuration, each control arm extending between a pair of commissural posts of the at least three commissural posts with a first end attached to one commissural post of the pair of commissural posts and a second end attached to the other commissural post of the pair of commissural posts, each control arm configured to hold a native valve leaflet, wherein each control arm extends radially outward from the frame between the pair of commissural posts,wherein one of the at least three control arms is an asymmetric control arm that forms an asymmetric shape between the first and second ends thereof and the asymmetric shape of the asymmetric control arm between the pair of commissural posts is asymmetric relative to the central longitudinal axis of the frame andwherein a positional marker is positioned on the asymmetric control arm between the pair of commissural posts, the positional marker positioned on the asymmetric control arm closer to one commissural post of the pair of commissural posts than to the other commissural post of the pair of commissural posts, andwherein the asymmetric shape of the asymmetric control arm differs from a shape of all other control arms of the at least three control arms of the prosthetic heart valve.

Abstract
Medical devices for positioning a valve in a subject'"'"'s body, such as a prosthetic heart valve in a subject'"'"'s heart, are disclosed. The prosthetic heart valve may include a valve assembly, a frame, and a control arm. The prosthetic heart valve may include a commissural post or multiple commissural posts. The prosthetic heart valve may include a positional marker on a control arm. The prosthetic heart valve may include multiple positional markers on one or more control arms. The positional markers can be shapes, characters, or other symbols. The positional markers may themselves be asymmetric. The positional markers may be placed in an asymmetric location on a control arm. The control arm may be asymmetrically shaped.
