Leaflet capture and anchor deployment system

Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, a leaflet connector carried by a distal end of the catheter can be anchored to a superior surface of a mitral valve leaflet. A needle is axially advanceable through the leaflet connector and through the leaflet. A leaflet anchor having a leaflet suture can be advanced out of the needle to secure the mitral valve leaflet to the leaflet suture. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae.

Heart valve clamp

The application relates to a heart valve clamp, comprises a fixed arm mechanism, a clamping arm mechanism, and a driving mechanism. The fixed arm mechanism comprises a fixed arm body and at least two fixed arms, extending outward from the fixed arm body, and integrally formed with the fixed arm body. The clamping arm mechanism comprises a clamping arm body connected to a bottom of the fixed arm body, and at least two clamping arms extending outward from the clamping arm bodies and integrally formed with the clamping arm body; and the driving mechanism comprises a second driving assembly that drives the fixed arm and the clamping arm to open or close. The fixed arm mechanism and the clamping arm mechanism of the entire heart valve clamp respectively forms an integral form, which can avoid the risk of the fixed arm or the clamping arm being disengaged, the stability of the whole structure is better. The fixed arm and the clamping arm clamp the valve leaflets under three-dimensional ultrasound and angiography navigation, so that the regurgitation area is reduced, which is capable of treating mitral or tricuspid regurgitation while keeping heat beating.

METHOD AND DEVICE FOR MITRAL REPAIR INCLUDING PAPILLARY MUSCLE RELOCATION

A delivery catheter as disclosed herein may be configured in various embodiments to minimize the potential for entanglement between cardiac repair components such as between sutures and coupled anchors. In various embodiments this is achieved by separating an anchor translation channel from a suture translation channel while maintaining the coupling between the anchor and the suture.

The reinforcement member can include a suture with a plurality of apertures. Sutures with apertures can be utilized within or as reinforcement members, which can be attached to a prosthetic valve to reinforce the prosthetic valve.

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.

PROSTHETIC HEART VALVE LEAFLET ASSEMBLIES AND METHODS
20220409368 · 2022-12-29 ·

An assembly and associated method for a commissure of a prosthetic heart valve is disclosed. As one example, a method includes forming a plurality of commissures with the plurality of leaflets, wherein each commissure is formed by pairing a first commissure tab of a first leaflet with an adjacent, second commissure tab of a second leaflet, and coupling a support strip to the first and second commissure tabs via sutures forming stitches along the support strip, and, for each commissure, securing the commissure to a respective support of a frame by forming one or more suture loops around an external surface of the support strip and the respective support of the frame, the suture loops being formed by end portion extensions of the sutures.

TRANSCATHETER DELIVERABLE PROSTHETIC HEART VALVES AND METHODS OF DELIVERY

A prosthetic valve includes a frame and a flow control component. The frame has an aperture extending through the frame about a central axis. The flow control component is mounted within the aperture and is configured to permit blood flow in a first direction approximately parallel to the vertical axis from an inflow end to an outflow end of the flow control component and to block blood flow in a second direction, opposite the first direction. The frame has an expanded configuration with a first height along the central axis, a first lateral width along a lateral axis perpendicular to the central axis, and a first longitudinal length along a longitudinal axis perpendicular to the central axis and the lateral axis. The frame has a compressed configuration with a second height less than the first height and a second lateral width less than the first lateral width.

Stent graft having an internal bidirectional branch

A stent graft having an internal bidirectional branch formed from a tubular segment of graft material. The internal bidirectional branch extends within the lumen of the stent graft and proximally and distally from a lateral opening in the sidewall of the stent graft. The tubular segment from which the stent graft is made is partitioned into first and second sections along a length of the tubular segment to form the internal bidirectional branch. The lateral opening has a length and a width that may be greater than the diameter of the internal bidirectional branch and may be in the shape of a quadrilateral. The internal bidirectional branch and the stent graft are formed from a single piece of graft material.
