Abstract: A surgical system for performing an endoscopic submucosal dissection includes first and second surgical clips each having first and second jaw members for grasping tissue therebetween. The first surgical clip includes a resilient member attached to one of the jaw members and configured to bow outwardly to engage tissue. The jaw members of the first surgical clip each has a pointed tip and each of the jaw members of the second surgical clip has a blunt distal tip.

Abstract: This invention discloses a valved stent for implantation at a dysfunctional or diseased atrioventricular valvular annulus. The valved stent is expandable from a collapsed shape to an expanded shape for minimally invasive delivery and has a low profile at the atrial or superior aspect to achieve improved hemodynamics and offers the capability to fabricate replacement valves having large diameters, The invention also includes a delivery apparatus uniquely designed for implantation of the valved stent and offering the potential for controlled and precise placement of the valved stent at the atrioventricular annulus. The invention also includes methods for use of the above devices and for treating diseased atrioventricular valves.
