A valve repair device includes a first paddle, a second paddle, a spacer, a first gripping member, and a second gripping member. The first paddle and the second paddle are configured to move between a closed position and an open position. The spacer is disposed between the first paddle and the second paddle. The first gripping member is disposed between the first paddle and the spacer. The second gripping member is disposed between the second paddle and the spacer. The first paddle and the first gripping member are configured to capture a first native valve leaflet. The second paddle and the second gripping member are configured to capture a second native valve leaflet.

Native valve repair devices and procedures

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 clasps include a fixed arm and a plurality of movable arms. The implantable prosthetic device can be used to repair a native valve, such as a native mitral valve.

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.

An device for treating a native valve includes a sealing element and an anchoring element. The sealing element is made from a braided mesh material. The sealing element is dimensioned to be deployed in an annulus of a native valve of a heart at a position between native valve leaflets to contact the native valve leaflets during ventricular systole to create a seal to prevent regurgitation of blood from the left ventricle to the left atrium. The sealing element is configured to both be radially expanded and radially reduced while at the position between the native valve leaflets. The anchoring element is adapted for deployment in the heart, the anchoring element coupled to the sealing element and configured to support the sealing element at the desired position between native valve leaflets.

A valve repair system for repairing a native valve of a patient includes a catheter and a valve repair device. The valve repair device is disposed in the catheter. The valve repair device comprises a compressible spacer and a pair of paddles. The pair of paddles are moveable between an open position and a closed position. The valve repair device can transition to a compressed configuration with the compressible spacer between the pair of paddles in the closed position.

A septal closure and port device for implantation in the atrial septum of a patient's heart includes an expandable frame with a central portion defining a lumen, and first and second opposing end portions. The frame can expand and contract between a compressed, tubular configuration for delivery through the patient's vasculature and an expanded configuration in which the first and second end portions extend radially outwardly from the opposite ends of the central portion. The device can also have a valve member supported on the frame and positioned to block at least the flow of blood from the left atrium to the right atrium through the lumen of the frame. The valve member permits a medical instrument to be inserted through the lumen and into the left atrium, for performing a subsequent medical procedure in the left side of the heart.

Trans-septal closure and port device

A system for implanting a repair device onto a native valve of a natural heart to repairing the native valve of a patient during a non-open-heart procedure. The system includes a pair of paddles and a pair of gripping members. The paddles are moveable between an open position and a closed position. The gripping members can have different configurations for effective attachment and release from the native valve of the patient.

Stent

A valve repair delivery handle includes a housing, an actuation control mechanism, and a clasp control mechanism. The actuation control mechanism includes a knob and an actuation tube. The knob is rotatably coupled to the housing. The actuation tube is coupled to the knob such that rotation of the knob in a first direction moves the actuation tube distally relative to the housing and rotation of the knob in a second direction moves the actuation tube proximally relative to the housing. The clasp control mechanism is coupled to the housing.

Valve repair delivery handle

A coronary artery check valve includes a stent configured to attach to an inner wall of a coronary artery of a living subject, and a tapered helical coil coupled to the stent and configured to regulate blood flow in the coronary artery. The coronary artery check valve is configured to prevent retrograde flow of the coronary blood supply during diastole by closing during systole of the heart when the tapered helical coil compresses longitudinally, and opening when the tapered helical coil expands longitudinally to permit blood flow into the coronary artery when a coronary pressure of the living subject drops below diastolic blood pressure.

Coronary artery check valve

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.

A valve repair device for repairing a native valve of a patient. The valve repair device includes a compressible spacer element, a pair of paddles, and a pair of gripping members. The pair of paddles are coupled to the spacer element. The pair of gripping members are disposed between the pair of paddles. The paddles and the gripping members are configured to attach to leaflets of a heart valve.

A valve repair devices and systems for repairing a native valve of a patient include a spacer, a pair of paddles, and a pair of moveable clasp arms. The pair of moveable clasp arms are disposed between the pair of paddles and the spacer. The moveable clasp arms are configured to attach to leaflets of a heart valve. The spacer, the pair of paddles, and the moveable clasp arms are configured such that, when attached to the leaflets, the moveable clasp arms are located between the spacer and first portions of the leaflet, while second portions of the leaflet engage the spacer.

A valve repair device for repairing a native valve of a patient includes a spacer element, a pair of paddles, and a pair of gripping members. The pair of paddles is coupled to the spacer element. The pair of gripping members is disposed between the pair of paddles. The paddles and the gripping members are configured to attach to leaflets of a heart valve. The spacer element extends past side edges of the gripping members, extends past side edges of the paddles, or extends past the side edges of both the gripping members and the paddles.

An expandable docking station frame includes a waist portion, a sealing portion connected to the waist portion, and a retaining portion connected to the sealing portion. The sealing portion is expandable radially outward of the waist portion to provide a seal against a first location of an inner surface of a circulatory system at a deployed position over a range of sizes of expansion. The retaining portion is expandable radially outward to engage a second location of the inner surface of the circulatory system at the deployed position, to retain the docking station at the deployed position in the circulatory system. When the expandable docking station frame is in an expanded and unconstrained state, the sealing portion and the retaining portion are joined by a concave profile portion radially inward of each of a first outermost diameter of the sealing portion and a second outermost diameter of the retaining portion.
