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.

Abstract: A vascular closure system for sealing an opening in a blood vessel may include an introducer sheath extending through the opening, the introducer sheath having a lumen extending through the introducer sheath, wherein partial withdrawal of the introducer sheath from the opening everts tissue of the blood vessel at the opening, and a shaping sheath slidably disposed over the introducer sheath, the shaping sheath having a split distal portion configured to engage the everted tissue.

Abstract: A support structure for a heart valve implant may include an expandable metallic scaffold configured to be actuated between a delivery configuration and a deployed configuration, and a seal member formed from a polymeric material, the seal member being disposed about the expandable scaffold, wherein a first portion of the seal member immediately adjacent the expandable scaffold is directly attached to the expandable scaffold and a second portion of the seal member immediately adjacent the expandable scaffold is unattached to the expandable scaffold.
