The present embodiments provide a medical device for implantation in a patient comprising a stent and a valve. The stent comprises a proximal region comprising a cylindrical shape having a first outer diameter in an expanded state, and a distal region comprising a cylindrical shape having a second outer diameter in the expanded state. The second outer diameter is greater than the first outer diameter. A proximal region of the valve is at least partially positioned within the proximal region of the stent, and the distal region of the valve is at least partially positioned within one of tapered and distal regions of the stent. When implanted, the proximal region of the stent and the proximal region of the valve are aligned with a native valve, and the distal region of the valve is distally spaced-apart from the native valve.

Stent structures for use with valve replacements

A stent for use in a medical procedure having opposing sets of curved apices, where the curved section of one set of apices has a radius of curvature that is greater than the curved section of the other set of apices. One or more such stents may be attached to a graft material for use in endovascular treatment of, for example, aneurysm, thoracic dissection, or other body vessel condition.

Low profile non-symmetrical stent

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.

The present embodiments provide a medical device for implantation in a patient-comprising a stent and a valve. The stent comprises a proximal region comprising a cylindrical shape having a first outer diameter in an expanded state, and a distal region comprising a cylindrical shape having a second outer diameter in the expanded state. The second outer diameter is greater than the first outer diameter. A proximal region of the valve is at least partially positioned within the proximal region of the stent, and the distal region of the valve is at least partially positioned within one of tapered and distal regions of the stent. When implanted, the proximal region of the stent and the proximal region of the valve are aligned with a native valve, and the distal region of the valve is distally spaced-apart from the native valve.

A device for delivering and deploying a radially expandable prosthesis is disclosed and comprises a proximal prosthesis release mechanism having a first resistance and a distal prosthesis release mechanism having a second resistance. The device further comprises an actuation mechanism for actuating the distal and proximal release mechanisms in a single coordinated movement and a biasing compensator for regulating the relationship between the first resistance and the second resistance. Additional aspects of the invention include devices and methods for delivering and deploying a radially expandable prosthesis.

Split sheath deployment system

The technology described herein relates to a stent graft and a method of making the stent wherein the stent comprises interconnected struts and is connected to the graft material by applying at least one band of polymer so as to cover at least a portion of at least some of the struts. A stent supported area is created by the stent's attachment to the graft material and the at least one band of polymer is applied so as to leave the majority of the stent supported area uncovered by the at least one band of polymer.

Stent attachment for endovascular aneurysm repair

An aortic stent-graft may include a tubular graft extending from a proximal end to a distal end, the graft comprising a proximal sealing portion and an intermediate portion, wherein a proximal end of the intermediate portion abuts the distal end of the proximal sealing portion. At least one sealing stent may be attached to the proximal sealing portion. A first fenestration window is disposed in the intermediate portion. The first fenestration window has a length determined by the equation L=1.23*D&#x2212;24 millimeters, where L is the length of the first fenestration window. D is between about 24 millimeters and 45 millimeters.
