摘要： A prosthetic mitral valve includes an anchor assembly, a 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 ventricular anchor and the atrial anchor are configured to flare radially outwards relative to the central portion. The annular strut frame is disposed radially within the anchor assembly and is attached to the anchor assembly. The central portion is configured to align with a native valve orifice and the ventricular anchor and the atrial anchor are configured to compress native cardiac tissue therebetween.

摘要： A delivery device includes a central elongate structure including an annular member at the distal end, a sheath, a plurality of tethers extending through the central elongate structure, a handle, and a control on the handle. The handle is connected to the elongate structure, the sheath, and the plurality of tethers. The control is configured to move the sheath proximally and distally over the central elongate structure. The annular member includes a plurality of pockets extending radially therearound. Each tether includes a feature on a distal end thereof configured to fit within a pocket of the plurality of pockets to hold the tethers in place.

摘要： An intravascular device delivery system has an elongated member with a flexible hypotube. The hypotube can be rotationally keyed to a steerable catheter. The flexible hypotube includes one or more cuts to allow bending of the flexible hypotube within a first plane. The steerable catheter is steerable to bend the flexible hypotube within the first plane, and longitudinally movable relative to the flexible hypotube to allow distal movement of the steerable catheter relative to a distal end of the flexible hypotube.

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.

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.
