Abstract: An outer sheath for use with a medical device delivery system includes a tubular member defined by a circumferential wall and having a distal end, a proximal end, and a lumen extending therebetween along a central longitudinal axis of the tubular member. The tubular has a distal region that is configured to shift between an enlarged configuration and a collapsed configuration. The distal region also includes at least one compression element configured to automatically radially collapse the distal region when the lumen of the distal region is empty.

Abstract: A heart valve remodeling device may include a delivery device including an inner shaft slidably disposed over a guidewire and an outer shaft slidably disposed over the inner shaft, and a braided stent fixedly attached to the inner shaft and the outer shaft. The braided stent may be translatable between an elongated configuration and a deployed configuration by movement of the inner shaft relative to the outer shaft. The braided stent may include a valve having two or more leaflets disposed within the braided stent. Adjacent leaflets of the two or more leaflets may form longitudinally-oriented commissures proximate a perimeter of the valve, the commissures being fixedly secured to the braided stent along their length.
