Valve repair systems and clips attachable to one or more leaflets of a heart valve. The systems and clips can have center member, first and second clipping arms, and a tubular member. The first and second clipping arms are movable between an open position and a closed position. The clipping arms including respective first end portions coupled together and respective second end portions extendable axially and radially outward. The tubular member is disposed about the first end portion of the center member and first end portions of the first and second clipping arms. Axial motion of the tubular member relative to the center member or axial motion of the center member relative to the tubular member causes corresponding movement of the clipping arms between the open and closed positions. Other implementations are also disclosed.

Percutaneous clip for repairing a heart valve

This application relates to methods, systems, and apparatus for replacing native heart valves with prosthetic heart valves and treating valvular insufficiency. In a representative embodiment, a support frame configured to be implanted in a heart valve comprises a main body formed by formed by a plurality of inner members forming an inner clover and a plurality of outer members forming an outer clover. The support frame can include gaps located between inner members of the plurality of inner members and outer members of the plurality of outer members. The inner clover can be radially inside the outer clover, and the outer clover can have larger dimensions than the inner clover. The support frames herein can be radially expandable and collapsible.

Valvular insufficiency repair device and method

Anchor devices and methods used to secure a prosthetic valve to a native valve annulus are described. The anchor device can be a separate expandable element from the prosthetic valve that is first advanced to the annulus and deployed, after which an expandable prosthetic valve is advanced to within the annulus and deployed. The combination of the two elements can apply a clamping force to the valve leaflets which holds the prosthetic valve in place. The anchor device can have a lower or ventricular portion and an upper or atrial portion. The anchor device can include one or more leaflet clamping portions. One, two, or more upstanding vertical posts between the clamping portions can extend upward at the valve commissures and support the upper portion, which can include one or more structures for leak prevention.

Valve anchor and installation method

This application relates to methods, systems, and apparatus for replacing native heart valves with prosthetic heart valves and treating valvular insufficiency. In some implementations, a heart valve leaflet clipping mechanism includes a delivery apparatus and clipping arms. The clipping arms are coupled to the delivery apparatus. The clipping arms are movable between an open position and a closed position. The two clipping arms are biased to the closed position. The delivery apparatus is configured to hold the clipping arms in the open position. The delivery apparatus is configured to allow the clipping arms to move to the closed position to engage native heart valve leaflet tissue.

In one representative embodiment, an implantable prosthetic device comprises a spacer body portion configured to be disposed between native leaflets of a heart, and an anchor portion configured to secure the native leaflets against the spacer body portion. The prosthetic device can be movable between multiple configurations. The spacer body can be configured to extend radially outwardly as the spacer body extends away from the distal end toward the proximal end. A delivery apparatus can have a first shaft and a second shaft, wherein movement of the first shaft relative to the second shaft moves the anchor portion relative to the spacer body.

Heart valve sealing devices and delivery devices therefor

A tissue anchor includes a driver head associated with a proximal portion of the tissue anchor, a pointed tip portion associated with a distal portion of the tissue anchor, a tissue-engagement portion disposed between the driver head and the pointed tip portion, and a cover configured to cover at least a portion of the tissue-engagement portion.

Corkscrew tissue anchor

An anchoring system comprises a first anchoring device comprising a first attachment mechanism and a plugging device and a second anchoring device comprising a second attachment mechanism, each of the first anchoring device and the second anchoring device being configured to enter a tissue wall at a proximal side of the tissue wall, the first anchoring device being configured to exit the tissue wall through a first hole on a distal side of the tissue wall, the second anchoring device being configured to exit the tissue wall at a second hole on the distal side of the tissue wall, the first attachment mechanism configured to attach to the second attachment mechanism outside of the distal side of the tissue wall, and the plugging device configured to cover the first hole and fit between at least a portion of the first anchoring device and the distal side of the tissue wall.

Pledgeted tissue anchor

Pinch devices and access systems that can be used to secure a prosthetic heart valve to a heart valve annulus and to treat valvular insufficiency. A pinch device can be a separate expandable element from the prosthetic heart valve that is first advanced to the annulus and deployed, after which an expandable prosthetic heart valve can be advanced to within the annulus and deployed. The two elements can clamp/pinch the heart valve leaflets to hold the prosthetic heart valve in place. The pinch device can have a flexible, expandable annular frame. A combined delivery system can deliver the pinch device and prosthetic heart valve with just a single access point and aid more accurate coaxial deployment. The pinch device can be mounted near distal end of an access sheath, and a catheter for delivering the prosthetic heart valve can be passed through a lumen of the same access sheath.

Heart valve pinch devices and delivery systems

In one representative embodiment, an implantable prosthetic device comprises a spacer body portion configured to be disposed between native leaflets of a heart, and an anchor portion configured to secure the native leaflets against the spacer body portion. The prosthetic device can be movable between multiple configurations. The spacer body can be made from braided, self-expandable metallic thread. A delivery apparatus can have a first shaft and a second shaft, wherein movement of the first shaft relative to the second shaft moves the anchor portion relative to the spacer body.

Valve repair systems and clips for attachment to one or more leaflets of a heart valve. The clip can include an elongated member configured to be positioned between two leaflets of the heart valve. The elongated member can have a first portion and a second portion that extends from the first portion. A width of the second portion can be greater than the width of the first portion. A pair of arms can be coupled to the first portion and extend toward the second portion. The pair of arms can extend radially away from the elongated member as the pair of arms extend away from the first portion toward the second portion when the arms are in an open position. And the pair of arms can be moveable from the open position to a closed position to pinch each leaflet between one of the arms and the elongated member.

An improved holder and storage system for a tissue-type prosthetic mitral heart valve that constricts the commissure posts of the valve and prevents suture looping. A rod axially movable relative to the holder tensions lengths of attachment sutures that extend between the commissure post tips to create a tent and flex the tips inward, thus helping to prevent looping of any of an array of pre-implanted sutures around the leading tips during delivery of the valve. The holder has a safety mechanism that prevents valve delivery before the rod is deployed. One embodiment automatically deploys the rod upon opening a storage jar. One embodiment permits a delivery handle to directly deploy the rod, while another uses a separate worm screw and coupling. A holder clip that attaches to a packaging sleeve may be formed of flexible members meshed together from which the heart valve and holder are easily pulled free to eliminate a step of decoupling the clip from the sleeve.

Mitral heart valve storage and handling system

A device for crimping a radially expandable and collapsible prosthetic valve comprises a crimping loop having a first end portion, a second end portion, and a loop portion extending between the first and second end portions and defining an opening configured to receive the prosthetic valve. The crimping loop is movable between a first state in which the opening has a first diameter and a second state in which the opening has a second diameter smaller than the first diameter such that when the prosthetic valve is positioned within the loop portion, movement of the crimping loop from the first state to the second state is effective to reduce a diameter of the prosthetic valve. A method for crimping a prosthetic valve comprises reducing a diameter of an opening of a crimping loop, thereby radially compressing an at least partially expanded prosthetic valve disposed within the opening.
