摘要： A method of delivering a prosthetic mitral valve includes delivering a distal anchor from a delivery sheath such that the distal anchor self-expands inside a first heart chamber on a first side of the mitral valve annulus, pulling proximally on the distal anchor such that the distal anchor self-aligns within the mitral valve annulus and the distal anchor rests against tissue of the ventricular heart chamber, and delivering a proximal anchor from the delivery sheath to a second heart chamber on a second side of the mitral valve annulus such that the proximal anchor self-expands and moves towards the distal anchor to rest against tissue of the second heart chamber. The self-expansion of the proximal anchor captures tissue of the mitral valve annulus therebetween.

摘要： An implantable device for occluding a septal defect has interleaved frame sections that allow flexibility to conform to a variety of defect geometries and provide reliable occlusion during endothelialization. Left and right frames connect to opposite ends of a floating connection post. The device is resiliently deformable and is biased into a natural state wherein, in situ in a variety of defect geometries, the device applies a sandwiching force to the tissue surrounding the defect that is relatively uniform across its diameter, improving stability and promoting occlusion.
