First Claim
1. A prosthetic heart valve comprising;
- a biological valve assembly;
a frame coupled to the biological valve assembly;
the frame comprising;
a first commissural post;
a second commissural post; and
a control arm attached to the first commissural post and the second commissural post;

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.

15. A method of implanting a prosthetic heart valve, the method comprising:
-
placing a prosthetic heart valve at least partially in a heart of a subject, wherein the prosthetic heart valve comprises a valve assembly, a frame, and two or more commissural posts coupled to the frame, the posts being arranged circumferentially around a central longitudinal axis of the valve assembly, and the frame is configured to assume a collapsed state and an expanded state, and a control arm attached to two different commissural posts, and the control arm having a positional marker, and wherein placing the prosthetic heart valve in a heart of a subject comprises placing the prosthetic heart valve in a vicinity of a native heart valve having native commissures, while the commissural posts are in the collapsed state, generating a fluoroscopic image of the native commissures and the prosthetic heart valve; determining whether one post of the prosthetic heart valve is aligned with one native commissure and determining the position of the positional marker relative to the native heart valve; and rotating the prosthetic heart valve to correct a rotational alignment of the prosthetic heart valve with the native commissure, wherein the posts are in the expanded state after the prosthetic heart valve is rotated. - View Dependent Claims (16, 17)
