Abstract: A prosthetic heart valve has a plurality of valve leaflets that control directional flow of blood through a heart and a stent structure having a plurality of commissure posts supporting the valve leaflets. The stent structure has a covering over the plurality of commissure posts and has a sewing ring at an inflow end of the stent structure. Each of the plurality of commissure posts has a tip and a suture loop is attached to the covering at a location adjacent to or on the tip of the commissure post. Each suture loop provides a passage for a suture to pass through between the covering and the suture loop.

Abstract: Systems, apparatuses, and methods disclosed herein may be directed to clips for medical implementation, including clips for a portion of a heart. The clips may be configured to close the portion of the heart, to reduce blood flow therethrough as well as passage of clots or other undesired materials. In examples, the clips may be configured to close the left atrial appendage (LAA). The closure of the LAA may reduce the possibility of stroke or other maladies stemming from fluid flow with the LAA. In examples, the clips may be positioned exterior of the LAA, to extend over an outer surface of the LAA for closure.
