摘要： A prosthetic mitral valve includes an anchor assembly, an annular strut frame, and a plurality of replacement leaflets secured to the annular strut frame. The anchor assembly includes a ventricular anchor, an atrial anchor, and a central portion therebetween. The annular strut frame is disposed radially within the anchor assembly. An atrial end of the annular strut frame is attached to the anchor assembly such that a ventricular end of the annular strut frame is spaced away from the anchor assembly.

摘要： A prosthetic mitral valve includes a proximal anchor, a distal anchor, and a central portion therebetween. The proximal and distal anchors each include a first outer frame and a second outer frame. The first outer frame includes a plurality of first arcs joined together, and the second outer frame includes a plurality of second arcs joined together. The plurality of first arcs are out of phase relative to the plurality of second arcs.

摘要： The present invention comprises a novel and safer mechanism of deployment using a self-positioning, self-centering, and self-anchoring method. To embody the present invention, a disk-based valve apparatus allowing the repositioning and retrieval of the implantable valve while working on a dysfunctional valve structure is disclosed. The disk-based valve apparatus may comprise one or more disks, either proximal or distal, a valve-housing component and a valve component. The one or more disks may be either proximal or distal, may be either connected to each other or disconnected from each other and may either be symmetrical or have different shapes and dimensions. The disk-based valve apparatus may be self anchoring, such as anchored by pressure from the one or more disk, or may be anchored using any anchoring.

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： A delivery guidewire for navigating a catheter in the heart to deliver a valve prosthesis. The delivery guidewire comprising an elongated core, an outer sleeve disposed on the elongated core, and a coil disposed on a distal portion of the elongated core. The delivery guidewire having a first section having a generally uniform diameter and a second section having a tapering section. A distal portion of the second section of the delivery guidewire comprises a pigtail shape atraumatic tip which can remain in the left ventricle.
