Heart valve sealing devices and delivery devices therefor

An implantable prosthetic device includes a coaption portion, paddles, and clasps. The paddles are moveable from a closed position to an open position. The clasps are also moveable from an open position to a closed position. The implantable prosthetic device can be used to repair a native valve, such as a native mitral valve. Other embodiments are also described.

LEAFLET SUPPORT
20220047388 · 2022-02-17 ·

A leaflet support for use with a native valve of a heart of a subject includes a frame that defines an array of adjoining cells, as well as an aperture between an upstream side and a downstream side of the frame. When placed against an annulus of the heart, the frame facilitates blood flow, via the cells, between the upstream side and the downstream side. The leaflet support further includes a barrier that is impermeable to blood flow, and that is coupled to the frame in a manner that obstructs blood flow through the aperture. The leaflet support further includes ventricular legs, that each extend radially outward and upstream, toward the frame. Other embodiments are also described.

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.

Modular stem extension

The modular stem component may include a shaft portion, a head, and a sleeve. The shaft portion is configured for receipt within the intramedullary canal of a bone and the head is configured to receive another component of a modular prosthetic system, such as a femoral neck, thereon. In one exemplary embodiment, the head extends radially around at least a portion of the stem and includes a rib defining a flange extending therefrom. The sleeve, which is formed as an independent part of the modular stem component and is made at least partially of a highly porous biomaterial, includes opposing ends and has a bore extending therethrough. The bore is configured to facilitate sliding receipt of the sleeve on the head.

Multi-walled placeholder

A placeholder for vertebrae or vertebral discs includes a tubular body, which along its jacket surface has a plurality of breakthroughs or openings for over-growth with adjacent tissue. The placeholder includes at least a second tubular body provided with a plurality of breakthroughs and openings at least partially inside the first tubular body. The first and second tubular bodies can have different cross-sectional shapes, can be are arranged inside one another by press fit or force fit or can be connected to each other via connecting pins and arranged side by side to one another in the first body.

Non-axisymmetric aortic valve devices

The present disclosure provides aortic valve prosthetic devices that are constructed in a non-axisymmetric shape, or are expandable to a non-axisymmetric shape for improved results in the repair of defective aortic valves. The devices can be surgically implanted, or they can be implanted percutaneously through an insertion catheter. The expandable devices can be self-expanding or expanded by an inflatable balloon to a non-axisymmetric cross-section geometry.

Tubular graft

A tubular graft comprising an internal helical formation which imparts helical flow on fluid passing through the tubular graft. One end of the tubular graft is tapered from an inner base to an outer tip.

Method of crimping stent on catheter delivery assembly

A method of crimping a stent is disclosed. The stent includes a minimum crimped diameter such that in the minimum crimped diameter, a pair of stent rings, between which marker support structures reside, do not make contact with the marker support structures. The crimped profile of the stent of the present invention can be as small as the crimped profile of a same stent but without the maker support structures.

Protuberant aneurysm bridging device deployment method

An aneurysm bridging device can be placed in the neurovasculature of a patient by advancing the aneurysm bridging device in a small-diameter configuration a delivery catheter to a target region within the neurovasculature and securing the distal region of the aneurysm bridging device to the neurovasculature. While the distal region of the aneurysm bridging device is secured to the neurovasculature, the proximal region of the aneurysm bridging device can be advanced to permit the aneurysm bridging device to expand from the small-diameter configuration and to deform and twist in a central region of the aneurysm bridging device. The proximal region of the aneurysm bridging device can be secured within the neurovasculature to maintain the central region of the aneurysm bridging device in a deformed state.
