Retaining mechanisms for prosthetic valves

Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve assembly. In embodiments, a prosthetic heart valve assembly, including a self-expandable support structure and a self-expanding heart valve, are advanced through the aortic arch of a patient using a delivery system. The support structure, which includes a plurality leaflet retaining arms, is at least partially expanded and positioned on or adjacent to the outflow side of the aortic valve. The prosthetic heart valve is positioned in the aortic valve. The prosthetic heart valve is expanded while it is within an interior of the support structure and while the support structure is positioned on or adjacent to the outflow side of the aortic valve, thereby causing one or more native leaflets of the aortic valve to be frictionally secured between the arms of the support structure and the expanded prosthetic heart valve.

VALVE DELIVERY SYSTEM INCLUDING FORESHORTENING COMPENSATOR FOR IMPROVED POSITIONING ACCURACY
20230210661 · 2023-07-06 ·

A system including a self-expanding prosthesis configured to foreshorten during deployment thereof and a delivery device configured to percutaneously deliver the self-expanding prosthesis. The delivery device includes a handle having an actuator thereon, an outer sheath including a proximal end coupled to the handle and a pusher shaft slidingly disposed within the outer sheath. The pusher shaft has a proximal end coupled to the handle and a distal end configured to releasably couple to the self-expanding prosthesis such that the self-expanding prosthesis axially moves therewith. The inner shaft has a distal portion of the inner shaft that is configured to receive a self-expanding prosthesis thereon. The outer sheath and the pusher shaft are configured to simultaneously move in opposing axial directions via actuation of the actuator on the handle to compensate for the foreshortening of the self-expanding prosthesis during deployment.

Annuloplasty device

An annuloplasty device is disclosed comprising first and second support rings being configured to be arranged as a coil in a first configuration around an axial direction, wherein the first and second support rings are configured to be arranged on opposite sides of native heart valve leaflets of a heart valve, wherein the first and second support rings are separated with a first pitch distance in the axial direction, in the first configuration, wherein the first and second support rings are configured to assume a contracted state having a second pitch distance in the axial direction being shorter than the first pitch distance, and wherein the first and second support rings are configured to be transferable between the first configuration and the contracted state to pinch the heart valve leaflets. A method of repairing a defective heart valve is also disclosed.

Prosthetic heart valve and delivery apparatus

A delivery assembly includes a prosthetic device, a catheter shaft, a release wire, a first line, and a second line. The prosthetic device has a first arm and a second arm. The release wire extends through the catheter shaft. The first line includes a first loop. The first line extends from the catheter shaft, through the first arm of the prosthetic device, and to the release wire, where the release wire extends through the first loop. The second line includes a second loop. The second line extends from the catheter shaft, through the second arm of the prosthetic device, and to the release wire, where the release wire extends through the second loop.

Clip-secured implant for heart valve
11690712 · 2023-07-04 · ·

An implant includes a primary structural element, and two clips coupled to the primary structural element, on opposite lateral sides of the primary structural element from each other, each of the clips having a first clip element and a second clip element. The implant is transluminally advanced to a heart valve of a subject. The implant is coupled to leaflets of the valve (i) by, for each of the clips, closing the clip around a central part of a respective leaflet of the valve by causing deflection between the first clip element and the second clip element, thereby sandwiching the central part of the respective leaflet between the first clip element and the second clip element, and (ii) such that the leaflets form a double orifice configuration, with the primary structural element disposed between the central parts of the leaflets. Other embodiments are also described.

PROSTHETIC HEART VALVE LEAFLET COMMISSURE ASSEMBLIES AND METHODS

A prosthetic heart valve and associated methods for assembling a prosthetic heart valve including a plurality of leaflets is disclosed. As one example, a prosthetic heart valve includes a frame; a plurality of commissure support elements, each connected the frame and including two axially-extending members spaced apart from one another to form a window; and a plurality of leaflets, each leaflet comprising a body and two opposing commissure tabs, each commissure tab arranged adjacent to another commissure tab to form a pair of commissure tabs that are disposed in a commissure support element to form a commissure. Each commissure tab includes a series of overlapping layers that include a first set of two overlapping layers that extends through the window and a second set of two overlapping layers that extends away from the first set of two overlapping layers and over an outer side of a corresponding axially-extending member.

DELIVERY APPARATUS HAVING NOSECONE WITH A BALL JOINT
20220409410 · 2022-12-29 ·

A delivery apparatus for an implantable medical device includes a handle, a shaft having a proximal end portion and a distal end portion, the proximal end portion being coupled to the handle, and a nosecone coupled to the distal end portion of the shaft. The nosecone includes a proximal end portion and a distal end portion pivotably coupled to the proximal end portion.

Surgical delivery device and method of use

A delivery device for a stented heart valve includes a handle, an elongate shaft extending from a distal end of the handle, and a conical housing having a proximal end coupled to the elongate shaft and an open distal end, the conical housing having a conical lumen therein with a first internal diameter adjacent to the proximal end of the conical housing and a larger second internal diameter adjacent to the open distal end of the conical housing.

Annulus plane catheter
11534574 · 2022-12-27 ·

A coaxial multilumen annulus plane catheter, including an outer pigtail catheter enclosing one or two additional lumens, each housing either a slidable shaped wire or a second pigtail catheter shaped to fit into a wide range of annulus diameters and/or depths. In embodiments, the device may include a catheter delivery handle with thumb/finger-actuated sliders that extend or retract the shaped wires and are sized to enable side-to-side or radial motion, imparting a torque to the pre-shaped wires which translates the length of the wires to enable individually controlled rotation or sweep of each wire to accommodate different annulus diameters. The delivery handle includes hemostasis controls and flush ports. In other embodiments, a handle is obviated by direct lumen axial and rotational control at a proximal end.
