Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Embodiments of a heart shape preserving anchor are disclosed herein. The heart shape preserving anchor can include a frame having one or more wings extending from a lower end of the frame. The frame can be sized and shaped to distribute forces over a large surface area thereby reducing pressures applied on the heart. The anchor can include a tether for coupling to a prosthesis, such as a replacement heart valve prosthesis. In some embodiments, the anchor can include a tether adjustment mechanism which can be wirelessly operated to adjust a length of the tether relative to the frame.

Abstract: 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.

Abstract: A prosthetic heart valve assembly includes a self-expandable stent having an inlet end and an outlet end and a passageway extending therethrough. The stent includes a plurality of rows of prongs on the outer surface of the stent. A valve portion comprising a plurality of leaflets is positioned within the passageway for permitting blood to flow through the passageway from the inlet end to the outlet end while blocking flow in the opposite direction. The stent further includes a flared upper portion shaped for placement along a supra-annular surface of an annulus for preventing downward migration of the prosthetic valve assembly into a ventricle. Each of the prongs has a tip pointing toward the inlet end for penetrating surrounding tissue and preventing upward migration of the prosthetic heart valve assembly toward an atrium.

Abstract: Prosthetic valve systems for replacing a native valve exhibiting regurgitation include a support structure and a transcatheter heart valve (THV) that is separate from the support structure. The support structure can be configured to be positioned such that it extends annularly around the native valve leaflets. After the support structure is deployed around the native valve leaflets, the THV can be expanded within the support structure such that the native valve leaflets are engaged between the support structure and the THV.
