Abstract: Prosthetic heart valves may be delivered to a targeted native heart valve site via one or more delivery catheters. In some embodiments, the prosthetic heart valve includes structural features that securely anchor the prosthetic heart valve to the anatomy at the site of the native heart valve. Such structural features can provide robust migration resistance. In addition, the prosthetic heart valves can include structural features that improve sealing between the prosthetic valve and native valve anatomy to mitigate paravalvular leakage. In particular implementations, the prosthetic heart valves occupy a small delivery profile; thereby facilitating a smaller delivery catheter system for advancement to the heart. Some delivery catheter systems can include a curved inner catheter to facilitate deployment o the prosthetic heart valve to a native tricuspid valve site via a superior vena cave or inferior vena cave.

The opening can move relative to the perimeter region of the crimped adapter to accommodate positioning of a branch prosthesis extending through the crimped adaptor. The vascular prosthesis is implanted in a patient to thereby treat, for example, an arterial aneurysm that spans a region of an artery that includes at least one arterial branch.

Abstract: A prosthetic heart valve (e.g., a prosthetic aortic valve) is designed to be somewhat circumferentially collapsible and then re-expandable. The collapsed condition may be used for less invasive delivery of the valve into a patient. When the valve reaches the implant site in the patient, it re-expands to normal operating size, and also to engage surrounding tissue of the patient. The valve includes a stent portion and a ring portion that is substantially concentric with the stent portion but downstream from the stent portion in the direction of blood flow through the implanted valve. When the valve is implanted, the stent portion engages the patient's tissue at or near the native valve annulus, while the ring portion engages tissue downstream from the native valve site (e.g., the aorta).

Abstract: An integrated valve prosthesis includes an anchor stent, a tether component, and a valve component. The anchor stent includes a self-expanding tubular frame member configured to be deployed in the annulus of an aortic valve or the aorta. The valve component includes a valve frame and a prosthetic valve coupled to the valve frame, and is configured to be deployed within the anchor stent. The tether component includes a first end coupled to the anchor stent and a second end coupled to the valve frame. In the delivery configuration, the tether component extends in a first direction from the anchor stent to the valve component, and in the deployed configuration, the tether component extends in a second direction from the anchor stent to the valve component. The second direction is generally opposite the first direction. The tether component may set the location of the valve component relative to the anchor stent.

Clasps attached to the paddles include fixed arms and moveable arms operable to secure the device to the patient's native valve leaflets.

Abstract: Modularizable implants and stents made with bio-absorbable metal wire alloys (‘bio-metals’, e.g. magnesium and alloys), and methods for making such implants and stents. The stents or implants may include one or more wire-formed rings or comprise inter-connected cells that form nets that may serve as modules that are assembled mechanically into stents, without the need for certain manufacturing processes that may affect the durability and physical properties thereof. The wires may be formed into rings mechanically and held in place using joining cuffs, and/or adjacent wires may be secured to one other mechanically using joining cuffs to form nets which can be used as implants or formed into stents. The stents can include radiopaque portions, e.g. associated with one or more joining cuffs, to aid in the positioning and evaluation of stents in the body by serving as visual indicators of alignment and expansion that can be detected using X-rays.
