摘要: Various stents and stent-graft systems for treatment of medical conditions are disclosed. In one embodiment, an exemplary stent-graft system may be used for endovascular treatment of a thoracic aortic aneurysm. The stent-graft system may comprise proximal and distal components, each comprising a graft having proximal and distal ends, where upon deployment the proximal and distal components at least partially overlap with one another to provide a fluid passageway therebetween. The proximal component may comprise a proximal stent having a plurality of proximal and distal apices connected by a plurality of generally straight portions, where a radius of curvature of at least one of the proximal apices may be greater than the radius of curvature of at least one of the distal apices. The distal component may comprise a proximal z-stent coupled to the graft, where the proximal end of the graft comprises at least scallop formed therein that generally follows the shape of the proximal z-stent. Further, the distal component may comprise at least one z-stent stent coupled to the distal end of the graft and extending distally therefrom that reduces proximal migration of the distal component.

摘要: The present examples provide a stent for use in a medical procedure that comprises at least one apex having first and second generally straight portions and a curved portion disposed between the first and second straight portions. The curved portion may comprise at least one region having a cross-sectional area that is less than a cross-sectional area of the first and second straight portions, which may facilitate compression of the stent and insertion of the stent into smaller vessels. The stent may be used alone, or in conjunction with a stent-graft, and may comprise one or more barbs configured to engage an inner wall of a vessel or duct.

摘要: A stent graft for use in a medical procedure to treat a dissection of a patient's ascending thoracic aorta. The stent graft includes bare alignment stents at least at a proximal end, and often with a stent at both ends, each stent having opposing sets of curved apices, where the curved section of one broader set of apices has a radius of curvature that is greater than the curved section of the other narrower set of apices. The proximal stent is flared in a manner such that its broad apices occupy a larger circumference around the stent than do its narrower apices, where this flared feature provides for anchoring engagement near the aortic root in a manner not interfering with the coronary arteries or the aortic valve.

摘要: A hybrid stent (100) includes at least one resilient ring (105) comprising a superelastic wire (102) formed in a sinusoidal pattern of alternating crests (110) and troughs (115) about a circumference of the ring (105). A plurality of malleable cannula segments (120) overlie the superelastic wire at the crests and troughs. Each of the cannula segments (120) includes a bend (125) and has an inner diameter sized to allow relative motion between the wire (102) and the cannula segment (120). The hybrid stent (100) may also include a plurality of gaps (130), where each gap (130) is defined by a spacing between opposing cannula segments (120). Deformation of the malleable cannula segments (120) dominates a response of the stent to substantially uniform radial forces, and deformation of the resilient ring (105) dominates a response of the stent to radially nonuniform crushing forces.
