摘要： A prosthetic device for replacing a deficient native aortic valve is disclosed, comprising: - a collapsible and expandable support stent formed of a shape memory alloy, - the support stent comprising a proximal stent portion (310) configured to expand to a first diameter and - an distal stent portion (320) configured to expand to a second diameter, the first diameter being smaller than the second diameter for preventing deformation of the mitral valve by over expansion and for providing a difference between the support stent and the openings of the coronary arteries; and - a collapsible and expandable valve assembly formed of natural tissue, whereby the valve assembly is attached to the support stent circumferentially along an inlet and sutured to the support stent along commissures for supporting the valve leaflets; wherein the first diameter of the support stent is sized for engagement with leaflets of the native aortic valve and the second diameter of the support stent is sized for engagement with the inner wall of the ascending aorta and wherein the stent is sized to avoid a contact with the inner wall of a left ventricle when implanted.

摘要： The present disclosure is directed to methods of manufacturing and passivating stents and other implantable medical devices including one or more attached radiopaque markers. In one embodiment, the method includes providing a metallic implantable medical device body without any radiopaque marker(s) attached thereto, primary electropolishing the device body without any markers attached thereto, attaching one or more radiopaque markers to the device body, and lightly electropolishing the device including device body and attached radiopaque markers. Light electropolishing removes no more than about 5 percent by weight of the device (i.e., the device body and attached marker(s)). Light electropolishing passivates the exposed surfaces of the device body and markers, while also providing electropolishing to the region of any welds where the radiopaque marker(s) attach to the device body.

摘要： A vertebral implant for fusing adjacent vertebrae or for replacing vertebral bodies is disclosed. The implant is a biocompatible metal, resorbable, or radiolucent implant conforming substantially in size and shape with an end plate of a vertebra. The implant preferably has a wedge-shaped profile to restore disc height and the natural curvature of the spine. The top and bottom surfaces of the implant have areas with a plurality of teeth to resist expulsion and provide initial stability and areas devoid of any protrusions to receive implantation instrumentation. The implant also has a stackability feature. The implant provides initial stability needed for fusion without stress shielding.

摘要： An endoluminal vascular repair system includes an aorta stent graft having a fenestration with a first reinforcement around the fenestration. The fenestration aligns with a branch vessel when deployed. A branch vessel stent graft has a flaring portion at a proximal end of the branch vessel prosthesis that has a second reinforcement around its circumference to engage the reinforcement around the fenestration, and a tubular portion. When deployed, the flaring portion retains the proximal end within the aorta stent graft, and the tubular portion extends through the fenestration and into the branch vessel.

摘要： A reinforcing and marker ring for a stent graft is disclosed. The reinforcing and marker ring comprises a plurality of turns of a substantially inextensible resilient wire in a circular shape and terminal ends at each end of the wire. The terminal ends each comprise a loop, each loop attachable to a stent graft having an opening or a fenestration so as to substantially lock a peripheral length of the circular shape. A marker winding is wound helically around the reinforcing wire, the marker winding being viewable on an image display system employing electromagnetic radiation so as to indicate the location of a periphery of the fenestration. The circular shape of the resilient wire, with the marker winding wound around it, is collapsible under radial pressure to form a squashed circular shape for loading into a delivery device, the squashed circular shape self-expandable back to a substantially circular shape upon release from the delivery device. The marker winding defines a curved passageway around the resilient wire of the reinforcing ring, the curved passageway having an internal diameter D, wherein the marker winding is helically wound with a pitch providing at least one winding per length D along the reinforcing wire of the reinforcing ring. The marker winding may be a radiopaque gold wire wound around a nitinol reinforcing wire.

摘要： Expandable elements having drug-delivery features and associated systems and methods are disclosed herein. In one embodiment, a drug-eluting stent includes a radially expandable cylindrical frame having a plurality of struts. The frame is transformable between a low-profile delivery state and an expanded deployed state. A plurality of drug-delivery features are carried by one of the struts and configured to deliver a drug to a treatment site within the patient or piercing through the tissue wall to break the constricting of the vessel wall inwardly. When the frame is in the expanded state within a body lumen of the patient, the drug-delivery features extend radially outwardly away from the strut and are configured to engage and, in some arrangements, pass through a wall of the body lumen.

摘要： A scaffold includes a marker connected to a strut. The marker is retained within the strut by a tongue-and-groove connection. The marker is attached to the strut by a process that includes pressing a non-circular marker into a rectangular hole of the scaffold strut. The strut sidewalls are restrained to produce the tongue and groove connection.

摘要： The present embodiments provide a stent (60) comprising a plurality of interconnected strut segments that enable expansion of the stent from a delivery state to a deployed state. A first strut segment and a second strut segment, of the plurality of strut segments, each comprise frontal surfaces facing radially inward in the deployed state and rear surfaces facing radially outward in the deployed state. The frontal surface of the first strut segment is at least partially stacked behind the rear surface of the second strut segment in the delivery state. A first barb (77) is coupled to at least a portion of the first strut segment. A sharpened tip of the first barb is aligned at least partially circumferentially behind at least one strut segment in the delivery state such that the sharpened tip is not radially exposed.
