Abstract: A prosthesis for placement within a native heart valve preferably includes an expandable frame having locking tabs disposed along a proximal end. A plurality of distal anchors is disposed along a distal end of the frame. Each distal anchor is provided with a cushion cover. An outer fabric member surrounds the frame and may extend outwardly from the frame in an expanded condition for providing an improved seal in the region of a native annulus. A valve body is positioned within an interior of the expandable from for allowing blood flow in only one direction. In preferred embodiments, the cushions are positioned over enlarged head portions of the distal anchors for further reducing trauma on surrounding tissue.

Abstract: A method of assembling a prosthetic heart valve includes providing a collapsible and expandable stent having an annulus section and an aortic section. The annulus section has a first diameter in a relaxed condition and a second diameter less than the first diameter in a collapsed condition. A constraint is applied to the stent to constrain the annulus section to a predetermined diameter between the first and second diameters. Applying a cuff and/or a plurality of leaflets to the stent in the constrained condition enables less material to be used. The resultant prosthetic valve is therefore able to be collapsed to a smaller diameter for introduction into a patient.

Abstract: A system includes a stent positionable within a coronary vein. The stent includes a valve and a stent body coupled to the valve and arranged to transition between a collapsed state and an expanded state. The system includes an intravascular reperfusion therapy device with a sensor and a catheter with a lumen shaped to receive the stent. The intravascular reperfusion therapy device delivers reperfusion therapy to a myocardium of a heart. The system includes a processor circuit that receives physiological data from the sensor, determines a progression of the reperfusion therapy, controls a configuration of the valve and/or the expansion state of the stent such that back pressure is controlled. With the stent in the expanded state, the stent body contacts a wall of the coronary vein and the valve obstructs blood flow in a first direction to generate the back pressure in an opposite, second direction.

Abstract: An implantable prosthetic device including a radially expandable and compressible frame having an inflow end portion and an outflow end portion. The frame including an actuator mechanism having a first frame member with a first inner bore and a second frame member with a second inner bore, the first and second frame members being spaced apart axially from one another, an actuator extending through the first and second inner bores, and a compressible cover member disposed over a portion of the actuator extending between the first and second frame members. Rotation of the actuator in a first direction causes the first and second frame members to move axially toward one another to expand the frame.

Abstract: A prosthetic device, such as a prosthetic heart valve, can include a radially compressible and expandable frame and a screw actuator that is coupled to the frame and configured to be rotated to radially expand the frame from a radially compressed state to a first radially expanded state. The frame includes an over-expansion structure that is configured to allow relative sliding movement between the screw actuator and the frame in a longitudinal direction to permit the frame to radially expand from the first radially expanded state to a second radially expanded state when an external expansion force applied to the prosthetic heart valve exceeds a predetermined force.

Abstract: Novel tools and techniques are provided for implementing protection of at least one tissue layer of a medical device or implant during crimping of the medical device or implant. In various embodiments, an implant tissue protection tool may include an outer portion configured to surround one or more outer segments of at least one tissue layer of a medical device to be implanted into a body of a subject and at least one protrusion (which may be affixed to a surface of the outer portion) configured to minimize or prevent occurrence (or likelihood of occurrence) of the at least one tissue layer (in some cases, leaflet material, or the like) of the medical device passing through at least one opening defined by a frame structure of the medical device during crimping of the medical device by a crimping device in preparation for implantation into the body of the subject.

Abstract: A prosthetic valve is provided that includes a tubular valve body and a plurality of prosthetic leaflets disposed within a lumen of the valve body. The valve body includes struts arranged in a cellular structure defined by first and second circumferential rows of four-sided closed cells. Each of the four-sided closed cells is defined by some of the struts, which are shaped so as to collectively define the following four sides: a left upstream side, a right upstream side, a left downstream side, and a right downstream side. The struts are joined at four corners of the four-side closed cell. Each of the four sides of each of the four-sided closed cells is double-strutted. Other embodiments are also described.

Abstract: The present invention provides a modular prosthetic valve device having two or more device modules for percutaneous delivery unassembled at or near the valve implantation site and assembly at least in part using a self-assembly member, and a system and method of folding, delivering and assembling the device. The device modules may include a support structure and a valve module. The valve module has an unassembled, folded delivery configuration, and an unfolded, assembled (via the self-assembly member) working configuration. The valve module may be a single-piece leaflets substructure or a plurality of valve sections. The self-assembly member has a delivery configuration and may be reverted to a preset configuration for valve module assembly. The unassembled valve module may be rolled along its circumferential axis towards its height to a folded diameter equivalent to one rolled leaflet, providing a percutaneous valve device having a smaller delivery diameter than pre-assembled valve devices.
