A prosthetic valve including a wire frame having a generally tubular body portion, an interior area, a longitudinal axis, a first end comprising a plurality of crowns, and a second end comprising a greater number of crowns than the first end. The wire frame includes a plurality of adjacent rows of modified diamond-shaped structures extending between the first and second ends. The prosthetic valve further includes a valve structure that includes a plurality of leaflets and that is attached within the interior area of the wire frame.

Stents for prosthetic heart valves

A system and method for restoring (e.g., replacing) a defective heart valve of a patient. A delivery system is manipulated to percutaneously deliver and implant a stented prosthetic heart valve to a native heart valve. A post-dilatation balloon is percutaneously delivered to the implantation site, and a compliant segment thereof is arranged within a region of the implanted prosthesis. The balloon is inflated such that the compliant segment expands and contacts the prosthesis, expanding a remodeling region of the prosthesis to a remodeled state. With these and related techniques, remodeling of an implanted, stented prosthetic heart valve to better match the native valve shape is possible, providing many benefits such as reducing the risk of paravalvular leaks.

Transcatheter prosthetic heart valve post-dilatation remodeling devices and methods

A method of forming an electrospun prosthetic valve includes utilizing a rotatable and angularly adjustable prosthetic valve mold. The prosthetic valve mold is set to a first angle. The prosthetic valve mold is rotated at a first rotational velocity and a first layer of electrospun fibers is deposited on the prosthetic valve mold. The prosthetic valve mold is stopped and a frame is positioned over the first layer. The prosthetic valve mold is set to a second angle. The prosthetic valve mold is rotated at a second velocity and a second layer of electrospun fibers is deposited on an outer surface of the first layer and an outer surface of the frame.

Prosthetic heart valve devices with tethered anchors and associated systems and methods are disclosed herein. A heart valve device configured in accordance with embodiments of the present technology can include, for example, a valve support for carrying a prosthetic valve. The valve support can be configured to be implanted at an annulus of a native mitral valve. The device can further include at least one elongated flexible member extending from the valve support in a ventricular direction, and an anchor coupled to the valve support via the elongated flexible member. The anchor can be shaped to wrap around an exterior area of an apical portion of the heart. In addition, the anchor can inhibit retrograde migration of the valve support.

Prosthetic heart valve devices with tethered anchors and associated systems and methods

A system for treating a vascular condition includes a conduit having an inner wall and at least one locking member positioned within the inner wall of the conduit. The system also includes a stented valve positioned in contact with the locking member within the inner wall of the conduit. A method for treating a vascular condition includes inserting a conduit with a stented valve into a target region of a vessel, positioning a contact portion of the stented valve against a locking portion of the conduit and preventing migration of the stented valve within the conduit based on the positioning.

Valved conduit designed for subsequent catheter delivered valve therapy

The present invention is a device for delivering a self-expanding stent. The device has an inner shaft and an outer shaft moveable with respect to the inner shaft. The self expanding stent is received on the inner shaft adjacent its distal end. A tapered tip is located on the inner shaft distal end and it forms a smooth transition from the delivery device to the guide wire extending therethrough. A handle allows the practitioner to deploy the stent single handedly. The stent may have its segments in a first radial configuration for deliver of the stent or the stent may have a plurality of segments in a first radial configuration and a plurality of second segments in a second radial position.

Stent delivery system

A method of texturing polycrystalline iridium includes the steps of cold/warm working of the polycrystalline iridium at equal to or below its re-crystallization temperature to break up the polycrystalline structure such that the orientation favors one direction (i.e. the &#x3c;110&#x3e; direction), and re-crystallizing the iridium such that a majority of grains are aligned in the preferred direction. The textured polycrystalline material is then used in vascular devices such as stents.
