Abstract
A delivery system for delivering, adjusting, and/or recapturing a stent-valve includes an inner shaft and an expandable stent-valve coupled to the inner shaft. The stent-valve has an upper portion, a lower portion, and a valve. The delivery system also includes a distal sheath disposed over at least the lower portion, a proximal sheath disposed over at least the upper portion, and at least one cinching member coupled to the stent-valve and extending through one of the inner shaft, the distal sheath, or the proximal sheath. The upper and lower portions of the stent-valve are configured to move to an expanded configuration when the proximal and distal sheaths are withdrawn, respectively. After at least a portion of the stent-valve has been moved to the expanded configuration, the at least one cinching member is configured to at least partially radially compress at least a portion of the stent-valve.
