Prosthetic valve delivery system with independently-movable capsule portions
First Claim
1. A method of releasing a valve from a delivery capsule in a heart, the method comprising:
- advancing the delivery capsule into the heart, the delivery capsule comprising a distal capsule portion and a proximal capsule portion, wherein the distal capsule portion and the proximal capsule portion are held together to retain the valve between the distal capsule portion and proximal capsule portion during the advancement of the delivery capsule into the heart;
moving the distal capsule portion a first distance in the heart in a first direction to release ventricular anchoring legs of the valve from the delivery capsule;
moving the proximal capsule portion a second distance in a second direction in the heart, opposite the first direction, to release atrial anchoring arms of the valve from the delivery capsule; and
after the release of the ventricular anchoring legs and the atrial anchoring arms from the delivery capsule, moving the distal capsule portion a third distance in the first direction in the heart to release an annular valve body of the valve from the delivery capsule.

Abstract
Embodiments of the present disclosure are directed to prosthetic valves and methods of use thereof. In one implementation, a method of releasing a valve from a delivery capsule in a heart may be provided. The method may include moving a distal capsule portion of the delivery capsule a first distance in the heart in a first direction. Such movement may release ventricular anchoring legs of the valve from the capsule, The method may also include moving a proximal capsule portion of the delivery capsule a second distance in a second direction in the heart. The first direction may be opposite the second direction. Such movement may release atrial anchoring arms of the valve from the capsule. The method may also include moving the distal capsule portion a third distance in the first direction in the heart, to thereby release an annular valve body of the valve from the capsule.

20. A method of releasing a valve from a delivery capsule in a heart, the method comprising:
-
moving a distal capsule portion of the delivery capsule a first distance in the heart in a first direction to release ventricular anchoring legs of the valve from the delivery capsule; moving a proximal capsule portion of the delivery capsule a second distance in a second direction in the heart, opposite the first direction, to release atrial anchoring arms of the valve from the delivery capsule; and moving the distal capsule portion a third distance in the first direction in the heart to release an annular valve body of the valve from the delivery capsule, wherein release of the ventricular anchoring legs from the delivery capsule occurs after release of the atrial anchoring arms from the delivery capsule.
