20220313438 · 2022-10-06 ·

An adhesive-applicator, and an implant that includes a wall formed from a porous fabric, are transcatheterally advanced to a heart of a subject. While a nozzle of the adhesive-applicator is disposed within an interior of the implant, the external surface of the wall is adhered to tissue of the heart by using the adhesive-applicator to apply an adhesive via the nozzle to the interior, such that a portion of the adhesive passes through the porous fabric of the wall to the external surface. Other embodiments are also described.

Apparatus and method for guide-wire based advancement of an adjustable implant

A tissue-engaging element has a distal portion configured to engage a portion of tissue of the heart. A guide member is reversibly coupled to the tissue-engaging element. An elongate implant has a distal end and a proximal end, at least the distal end being slidably coupled to the guide member. A tool is slidable along the guide member distally toward the tissue-engaging element while (i) the tool is coupled to at least the distal end of the elongate implant, and (ii) the guide member is coupled to the tissue-engaging element, such that sliding of the tool along the guide member distally toward the tissue-engaging element while (i) the tool is coupled to at least the distal end of the elongate implant, and (ii) the guide member is coupled to the tissue-engaging element, slides at least the distal end of the elongate implant toward the tissue-engaging element.

Prosthetic heart valve devices, prosthetic mitral valves and associated systems and methods

Prosthetic heart valve devices for percutaneous replacement of native heart valves and associated systems and method are disclosed herein. A prosthetic heart valve device configured in accordance with a particular embodiment of the present technology can include an anchoring member having an upstream portion configured to engage with tissue on or near the annulus of the native heart valve and to deform in a non-circular shape to conform to the tissue. The device can also include a mechanically isolated valve support coupled to the anchoring member and configured to support a prosthetic valve. The device can further include an atrial extension member extending radially outward from the upstream portion of the anchoring member and which is deformable without substantially deforming the anchoring member. In some embodiments, the upstream portion of the anchoring member and the extension member may be deformed while the valve support remains sufficiently stable.

Methods of assembling valved aortic conduits

A valved conduit including a bioprosthetic aortic heart valve connected to a tubular conduit graft forming an ascending aorta. The conduit graft may attach to the heart valve in a manner that facilitates a redo operation in which the valve is replaced with another valve. A sewing ring may be pre-attached to the inflow end of the graft, and then the valve connected to a delivery holder advanced into the graft and secured to the sewing ring. Dry bioprosthetic valves coupled with conduit grafts sealed with a bioresorbable medium can be stored with the delivery holder.

DEVICE, SYSTEM, AND METHOD FOR TRANSCATHETER TREATMENT OF VALVULAR REGURGITATION

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.

Implantable device having rounded struts and method of manufacture

An implant includes a frame comprising a tubular body formed by a plurality of interconnected struts that are manufactured to reduce stresses and strains resulting from component interaction during chronic use. At least a portion of a longitudinal corner of one or more struts of the frame may be chamfered, rounded, or otherwise modified to distribute stresses experienced at the strut corner throughout the strut body. Chamfering and/or rounding corners along at least a portion of a strut of the frame may reduce stresses on the frame caused by interactions between the frame and other components of the implant. The implant may be manufactured by cutting (e.g., laser cutting) a plurality of struts from a tubular metal alloy, polymer, or the like forming the tubular body, and softening at least a portion of an edge of the strut by cutting, grinding, and/or micro-blasting the edges of the corner.

SYSTEMS AND METHODS FOR RESHAPING A HEART VALVE

The present disclosure includes a device for reshaping a heart valve. The device may include a central ring about a central axis and a plurality of arms coupled to the central ring, each of the arms coupled to the central ring at a pivot point at a first end of the arm, the arm comprising an attachment feature at a second point along the arm, the pivot point configured to allow movement of the arm about the pivot point through a plane extending radially from the central axis through the arm. Additionally, the plurality of arms may be contractable and may be extendable such that the hooks extend beyond a dilated heart valve. The present disclosure also includes associated methods and systems.

Two Component Mitral Valve System Methods
20230200993 · 2023-06-29 ·

A method for transcatheter delivery to a native heart valve needing replacement. A first component is attached to the native annulus upstream of the native leaflets maintaining native leaflet function, and is held to the native annulus by barbs that are activated by a torus balloon after the first component is fully expanded. The torus balloon can be implanted along with the support frame. A limiting cable restricts further expansion of the first component and holds a second component that contains the replacement leaflets.

HEART VALVE STENTS ADAPTED FOR POST-IMPLANT EXPANSION

A prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be reshaped into an expanded form in order to receive and/or support an expandable prosthetic heart valve therein is disclosed, together with methods of using same. The prosthetic heart valve may be configured to have a generally rigid and/or expansion-resistant configuration when initially implanted to replace a native valve (or other prosthetic heart valve), but to assume a generally expanded form when subjected to an outward force such as that provided by a dilation balloon or other mechanical expander.

Valve replacement using rotational anchors

Features for a heart valve device are described. The device may include a frame with anchors configured to secure the device to tissue. The frame may include a flared end or skirt for additional securement of the implanted device. The device may include a seal such as a barrier and/or cuff for preventing leakage. The device may contract for endovascular delivery of the device to the heart and expand for securement within the heart, such as the within the native mitral valve annulus. The device may include a replacement valve. The valve may have leaflets configured to re-direct blood flow along a primary flow axis.
