SYSTEMS AND METHODS FOR SEPARATING NATIVE HEART VALVE LEAFLETS ATTACHED TOGETHER BY A FIXATION DEVICE

Systems and methods for separating native heart valve leaflets attached together by a fixation device. The system has elongate shaft including a proximal end portion, a distal end portion and a longitudinal axis extending therebetween. The elongate shaft is configured for transvascular delivery of the distal end portion to a native heart valve. A balloon is disposed at the distal end portion of the elongate shaft, and the balloon is inflatable from a collapsed condition to an inflated condition. At least one snare lumen extends along at least a portion of the balloon, the at least one snare lumen having an exit port defined therein. A snare is deployable through the exit port from a delivery position within the at least one snare lumen to an extended position extending beyond the exit port. The snare in the extended position is configured to capture the fixation device.

Annular augmentation device for cardiac valve repair
11491009 · 2022-11-08 · ·

The present disclosure relates to repair devices for repair of regurgitant mitral valves. A repair device includes a body having a perimeter defining an upper side and a lower side. An annular groove is disposed along a posterior section of the perimeter of the device and is configured to receive posterior rim tissue of a mitral valve annulus. First and second anchors extend from the body in an anterior direction. The first and second anchors are configured to engage with respective commissures of the mitral valve to assist in securing the repair device in position. The repair device is structured to minimize or eliminate imparting or transmitting radially outward forces along an anterior section so as to avoid imparting forces to the septum to avoid hindering the function of the aortic valve and the left ventricular outflow tract.

DEVICE, SYSTEM, AND METHOD FOR TRANSCATHETER TREATMENT OF VALVULAR REGURGITATION WITH SECONDARY ANCHORS
20230040410 · 2023-02-09 ·

The invention relates to a device for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation assistance element for implantation across the valve; a system including the coaptation assistance element and anchors for implantation; a system including the coaptation assistance element and delivery catheter; and a method for transcatheter implantation of a coaptation element across a heart valve.

Prosthetic valve with natural blood flow

A prosthetic valve may be formed to direct flow out of the outflow orifice toward a posterior portion of a heart wall. The prosthetic valve includes an expandable frame which may be covered with a cover that is suturelessly attached to the frame. The prosthetic valve may also include an outflow orifice size which is controlled. Methods of using these devices are also disclosed.

System for mitral valve repair and replacement

Systems for mitral valve repair are disclosed where one or more mitral valve interventional devices may be advanced intravascularly into the heart of a patient and deployed upon or along the mitral valve to stabilize the valve leaflets. The interventional device may also facilitate the placement or anchoring of a prosthetic mitral valve implant. The interventional device may generally comprise a distal set of arms pivotably and/or rotating coupled to a proximal set of arms which are also pivotably and/or rotating coupled. The distal set of arms may be advanced past the catheter opening to a subannular position (e.g., below the mitral valve) and reconfigured from a low-profile delivery configuration to a deployed securement configuration. The proximal arm members may then be deployed such that the distal and proximal arm members may grip the leaflets between the two sets of arms to stabilize the leaflets.

Mitral valve with free edge support

A transcatheter stent-valve having replacement leaflets that are attached along their free edges. The stent-valve frame has supports that extend distally of the replacement leaflets to two fastening sites. The replacement leaflets are attached along a leaflet base forming a linear attachment to the stent-valve frame. The free edges of the leaflets have cords attached; the cords attach the free edges of the leaflets to the fastening sites located on the supports. The stent-valve can be a single component stent-valve or it can be a second component of a dual component stent-valve.

APPARATUS AND METHODS FOR CLAMPING A MITRAL VALVE
20230029712 · 2023-02-02 ·

An apparatus for repairing or replacing a mitral valve and a method of using same are disclosed. The apparatus has an atrial band securable to a ring-shaped ventricular band. The ventricular band has an anterior band and a posterior band connectable to the anterior band. The atrial and anterior bands each have a pair of apertures. Each of the apertures is positioned proximate to a respective terminal end of the bands. The apertures of the atrial and anterior bands are arranged to align with one another when their inner surfaces engage. Means are provided to secure the atrial band to the anterior band. When delivered and implanted, the apparatus is arranged to extend across the commissures of the heart, with atrial and anterior bands arranged to press against the atrial and ventricular surfaces of the mitral valve leaflets respectively.

Systems and methods for heart valve therapy

Prosthetic heart valves described herein can be deployed using a transcatheter delivery system and technique to interface and anchor in cooperation with the anatomical structures of a native heart valve. Some embodiments of prosthetic valves described herein include an anchor portion that couples to the anatomy near a native valve, and a valve portion that is mateable with the anchor portion. In some such embodiments, the anchor portion and/or the deployment system includes one or more prosthetic elements that temporarily augment or replace the sealing function of the native valve leaflets.

Ringless web for repair of heart valves

A ringless web is configured to repair heart valve function in patients suffering from degenerative mitral valve regurgitation (DMR) or functional mitral valve regurgitation (FMR). In accordance with various embodiments, a ringless web can be anchored at one or more locations below the valve plane in the ventricle, such as at a papillary muscle, and one or more locations above the valve plane, such as in the valve annulus. A tensioning mechanism connecting the ringless web to one or more of the anchors can be used to adjust a tension of the web such that web restrains the leaflet to prevent prolapse by restricting leaflet motion to the coaptation zone and/or promotes natural coaptation of the valve leaflets.
