Abstract: A self-expanding wire frame for a pre-configured compressible transcatheter prosthetic cardiovascular valve, a combined inner frame/outer frame support structure for a prosthetic valve, and methods for deploying such a valve for treatment of a patient in need thereof, are disclosed.

Abstract: A prosthetic heart valve includes a self-expanding wire frame body, a valve disposed in the body, a leaflet clip coupled to the body, and a control element operably coupled to the leaflet clip. The body has a proximal end and a distal end. The leaflet clip is configured to be transitioned between a first configuration in which the prosthetic valve can be inserted into a heart, and a second configuration in which the leaflet clip is disposed to capture a native valve leaflet between the leaflet clip and the wire frame body when the body is disposed in a native annulus of an atrioventricular valve of a heart. The control element extends from the leaflet clip through a ventricle of the heart and out a wall of the ventricle to allow a user to transition the leaflet clip from its first configuration to its second configuration.

Abstract: In some embodiments, a method for delivery and deployment of a prosthetic mitral valve into a heart includes inserting an introducer sheath having a prosthetic mitral valve disposed therein in a collapsed configuration into the left atrium of a patient's heart, through a gap between the native mitral valve leaflets, the left ventricle and apex of the heart. An epicardial pad device coupled to the prosthetic valve via a tether is moved distally out of the sheath. The introducer sheath is withdrawn into the left atrium of the heart. An inner delivery sheath is extended distally from within the introducer sheath and disposed within the left atrium. The prosthetic mitral valve is moved distally out of the inner delivery sheath and assumes a biased expanded configuration. The valve is positioned within the mitral annulus of the heart, and secured in place via the tether and epicardial pad device.

Abstract: In some embodiments, an apparatus includes a catheter assembly and a handle assembly that can be removably coupled to the catheter assembly. A valve holding tube defines a lumen configured to receive a prosthetic mitral valve in a compressed configuration and can be removably coupled to a distal end portion of the handle assembly. The valve holding tube can be received within a hub of the catheter assembly when coupled to the handle assembly. The actuator when actuated is configured to cause the tensioning unit to travel along a traveler strap of the catheter assembly moving the handle assembly distally such that a distal end of an elongate shaft of the handle assembly moves the prosthetic mitral valve distally out of the valve holding tube and out a distal end of the sheath such that the prosthetic mitral valve is free to move to a biased expanded configuration.

Abstract: A bioadhesive delivery catheter includes a manifold, a dual lumen tube, and a mixing member. The manifold includes a delivery device passage and an injection port. The tube is insertable into the delivery device passage and includes first and second lumens positioned side-by-side. The first lumen extends proximal of the second lumen within the delivery device passage, and the second lumen is in flow communication with the injection port. The mixing member is positioned between a proximal inlet of the injection port and the second lumen and is configured to help mix a bioadhesive material that is delivered through the injection port into the second lumen.

Abstract: Apparatus and methods are described herein for various embodiments of a prosthetic heart valve, delivery apparatus and delivery methods for delivering a prosthetic heart valve to a heart of a patient via a transapical or transvascular delivery approach. In some embodiments, a prosthetic heart valve includes an outer frame coupled to an inner frame and the outer frame is movable between a first configuration relative to the inner frame and a second inverted configuration relative to the inner frame. The valve can be delivered to a heart using an apparatus that includes a delivery sheath that defines a lumen that can receive the prosthetic heart valve therein when the outer frame is in the inverted configuration. Actuation wires are releasably coupled to the outer frame and can be used to help revert the outer frame after the valve is deployed outside of the delivery sheath and within the heart.

Abstract: The invention relates to a medical prosthesis, and in particular a tether platform for attaching to or mounting on the septomarginal trabecula of the right ventricle for securing and positioning heart valve repair devices, and in particular for securing a heart valve substitute comprising a pliant tubular conduit mounted on a resilient annular frame and tethered to a non-perforating anchor within the right ventricle of the heart, wherein the pliant tubular conduit is a reciprocating mechanical member that is compressed by pressurized working fluid within the ventricle during systole.

Abstract: Apparatus and methods are described herein for use in the transfemoral delivery and deployment of a prosthetic mitral valve. In some embodiments, a method includes inverting an outer frame of a prosthetic mitral valve when in a biased expanded configuration. After inverting the outer frame, the prosthetic mitral valve is inserted into a lumen of a delivery sheath such that the mitral valve is moved to a collapsed configuration. The delivery sheath is inserted into a femoral vein and moved through the femoral vein and a septum of a heart until a distal end of the delivery sheath is disposed in the left atrium of the heart. The prosthetic mitral valve is moved distally out of the delivery sheath such that the inverted outer frame reverts and the prosthetic mitral valve assumes its biased expanded configuration. The prosthetic mitral valve is then positioned within a mitral annulus of the heart.

Abstract: A prosthetic heart valve can include an outer frame coupled to an inner frame such that the outer frame can be moved between a first position and a second position in which the outer frame is inverted relative to the inner frame. The inner frame and the outer frame define between them an annular space, and a pocket closure can bound the annular space to form a pocket in which thrombus can form and be retained. The pocket closure can include a stretchable pocket covering that can move from a first position in which the pocket covering has a first length when the outer frame is in the first position relative to the inner frame and a second position in which the pocket covering has a second length greater than the first length when the outer frame is in the second position relative to the inner frame.
