摘要： This invention relates to the design and function of a compressible valve replacement prosthesis, collared or uncollared, which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed focuses on the deployment of a device via a minimally invasive fashion and by way of example considers a minimally invasive surgical procedure preferably utilizing the intercostal or subxyphoid space for valve introduction. In order to accomplish this, the valve is formed in such a manner that it can be compressed to fit within a delivery system and secondarily ejected from the delivery system into the annulus of a target valve such as a mitral valve or tricuspid valve.

摘要： Apparatus and methods are described herein for use in the transvascular delivery and deployment of a prosthetic mitral valve. In some embodiments, a method includes inverting an outer frame of a prosthetic mitral valve when the valve is in a biased expanded configuration. After inverting the outer frame, the prosthetic mitral valve is inserted into a lumen of a delivery sheath such that the mitral valve is moved to a collapsed configuration. The distal end portion of the delivery sheath is inserted into a left atrium of a heart. The prosthetic mitral valve is moved distally out of the delivery sheath such that the inverted outer frame reverts and the prosthetic mitral valve assumes its biased expanded configuration. In some embodiments, actuation wires are used to assist in the reversion of the outer frame. The prosthetic mitral valve is then positioned within a mitral annulus of the heart.

摘要： A prosthetic heart valve includes a self-expanding wire frame body, a valve disposed in the body, a leaflet clip coupled to the body, and a control element operably coupled to the leaflet clip. The body has a proximal end and a distal end. The leaflet clip is configured to be transitioned between a first configuration in which the prosthetic valve can be inserted into a heart, and a second configuration in which the leaflet clip is disposed to capture a native valve leaflet between the leaflet clip and the wire frame body when the body is disposed in a native annulus of an atrioventricular valve of a heart. The control element extends from the leaflet clip through a ventricle of the heart and out a wall of the ventricle to allow a user to transition the leaflet clip from its first configuration to its second configuration.

摘要： This invention relates to the design and function of a single-tether compressible valve replacement prosthesis which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed combats the process of wear on anchoring tethers over time by using a plurality of stent-attached, centering tethers, which are themselves attached to a single anchoring tether, which extends through the ventricle and is anchored to a securing device located on the epicardium.
