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

A method of implanting a prosthetic heart valve assembly includes advancing a delivery catheter through a vein and toward a native heart valve. The prosthetic heart valve assembly is deployed from a lumen of the delivery catheter, allowing the prosthetic heart valve assembly to self-expand from a compressed state to a functional size within an annulus of the native heart valve with a flared upper portion of the stent located in an atrium against a supra-annular surface of the annulus of the native heart valve. An elongate anchoring member is attached to a septum of a ventricle at a location below the annulus. The flared upper portion contacts a supra-annular surface of the native heart valve for preventing downward migration of the prosthetic heart valve assembly toward the ventricle and the elongate anchoring member prevents upward migration of the prosthetic heart valve assembly toward the atrium.

Method of implanting a prosthetic heart valve assembly

Devices and methods of treating conditions cause or exacerbated by excessive fluid pressures or retentions, such as pulmonary hypertension, that involves shunting excessive fluid pressure from one bodily chamber or vessel to another bodily chamber or vessel.

Methods and technology for creating connections and shunts between vessels and chambers of biologic structures

A stretch-measurement probe includes an elongate outer sleeve, expansion feature associated with a distal portion of the outer sleeve, and an elongate inner rod disposed at least partially within the outer sleeve. The expansion feature is configured to allow a longitudinal distance between a proximal end of the outer sleeve and the distal end of the outer sleeve to be varied.

Atrial stretch measurement for atrial fibrillation prevention

A method treating a deficient native mitral valve includes advancing the distal end portion of a delivery catheter into a heart, wherein the delivery catheter contains a support band stretched into a linear form, wherein the support band comprises a shape-memory material, and then ejecting the support band from the distal end portion of the delivery catheter such that the support band transitions from the linear form to a curved shape extending around native leaflets of the native mitral valve.

Methods for treating a deficient native mitral valve

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.

A prosthetic heart valve assembly includes a self-expandable stent having a flared upper portion, a lower portion, and an intermediate portion extending from the upper portion to the lower portion. The stent includes upwardly bent hooks extending from an outer surface of the stent, which are adapted to engage native leaflet tissue. The stent further includes an elongate anchoring member extending from the lower portion of the stent, which is adapted to be secured to a ventricle wall via a prong portion. When deployed within the native heart valve, the flared upper portion contacts a supra-annular surface of the native heart valve for preventing downward migration of the prosthetic heart valve assembly toward the ventricle and the upwardly bent hooks and the elongate anchoring member prevent upward migration of the prosthetic heart valve assembly toward an atrium.

Prosthetic heart valve assembly

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

Prosthetic valve systems for treating a native valve exhibiting regurgitation can include a support structure in which a separate prosthetic heart valve can be placed. A method for implant a prosthetic valve system can include advancing a first catheter delivery sheath through an introducer sheath and into a left ventricle of a patient's heart, deploying at least a portion of a support structure from the first catheter delivery sheath and positioning the support structure around native leaflets of the patient's native mitral valve, positioning a prosthetic heart valve in a radially collapsed configuration within the patient's native mitral valve, and expanding the prosthetic heart valve from the radially collapsed configuration to a radially expanded configuration, wherein the prosthetic heart valve contacts the native leaflets from within the patient's native mitral valve and is separated from the support structure by the native leaflets.

Retaining mechanisms for prosthetic valves

A method of reducing regurgitation between native leaflets of an atrioventricular heart valve includes advancing a delivery catheter through a sheath, wherein the delivery catheter has a valve leaflet coaptation element mounted over a distal end portion. The coaptation element is positioned within the heart valve and is permitted to radially expand from a compressed configuration to an enlarged configuration for filling a gap between the native leaflets of the heart valve. After deployment, the position of the coaptation element is fixed relative to the heart valve, thereby reducing regurgitation between the native leaflets of the heart valve and improving heart function.

Methods for reducing cardiac valve regurgitation

Methods and devices that prevent stasis in the LAA by either increasing the flow through the LAA or by closing off or sealing the LAA. Increasing the flow is accomplished through shunts, flow diverters, agitators, or by increasing the size of the ostium. Closing off the LAA is accomplished using seals or by cinching the LAA.

Left atrial appendage stasis reduction

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.

Devices and systems for docking a heart valve

Prosthetic heart valves are described. Prosthetic heart valves can include radially expandable and compressible inner and outer metal frames. The inner frame can be disposed within a lumen of the outer frame and can be coupled to the outer frame. An outflow end of the inner frame can be coupled to and/or located at an outflow end of the outer frame. An end portion of the inner frame can be spaced radially inwardly from an inner surface of the outer frame, such that a radial gap exists between the inner surface of the outer frame and an outer surface of the inner frame. Prosthetic heart valves can further include a plurality of leaflets disposed within and supported by the inner frame, such as by commissure posts of the inner frame.

Prosthetic heart valve having an inner frame and an outer frame

An expandable stent for implantation in a right ventricular outflow tract includes a frame having a waist portion that expands to a deployed size having a first diameter, first and second sealing portions extending in opposite directions from the waist portion and expanding radially outward of the waist portion. The first and second sealing portions are sized to seal against first and second portions of the inner surface of the right ventricular outflow tract at the deployed position over a range of sizes of expansion larger than the first diameter. A band is secured to the waist portion of the frame, restricting expansion of the waist portion substantially beyond the first diameter, such that the waist portion is configured to be spaced apart from the inner surface of the right ventricular outflow tract at the deployed position.
