摘要： Embodiments of the present disclosure include an implantable assembly for a native heart valve that includes a prosthetic heart valve and a braided support structure. The prosthetic valve includes a frame and prosthetic leaflets. The braided support structure has an inner braided layer and an outer braided layer. The outer braided layer is disposed over the inner braided layer. The outer braided layer is less porous to blood than the inner braided layer. The braided support structure defines a plurality of arms that are angularly spaced around the prosthetic heart valve such that each arm extends radially outwardly from the prosthetic heart valve. Other embodiments are also described.

摘要： In a representative embodiment, an implantable assembly for a native heart valve comprises a prosthetic heart valve and first and second inflatable bodies. The prosthetic heart valve can comprise a frame and prosthetic leaflets. The first inflatable body can comprise first and second end portions, wherein the first end portion is configured to be secured to tissue of the native heart valve at a first location, and the second end portion is configured to engage an outer surface of the prosthetic valve. The second inflatable body can comprise third and fourth end portions, wherein the third end portion is configured to be secured to tissue of the native heart valve at a second location, and the fourth end portion is configured to engage the outer surface of the prosthetic valve. The first and second inflatable bodies anchor the prosthetic valve within the annulus of the native heart valve.
