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.

Methods and sensor delivery devices for monitoring a fluid pressure within a vascular structure, the devices including an elongated sheath sized for sliding along a guidewire, a sensor assembly including a fiber optic sensor, a housing surrounding the sensor, a first cavity between the distal end of the sensor and a distal aperture of the housing, a filler extending from at least the distal end of the housing distally and tapering inward toward the outer surface of the sheath, a second cavity in the filler with an opening at the outer surface of the filler and adjoining the distal aperture of the housing, and an optical fiber. The sensor delivery device may also include an outer layer that partially covers the second cavity with an aperture over the opening of the second cavity.

Fiber optic sensor assembly for sensor delivery device

The present embodiments provide a stent for use in a medical procedure that comprises a series of proximal apices disposed at a proximal end of the stent and a series of distal apices disposed at a distal end of the stent. A trigger wire is adapted to be coupled to at least one of the proximal apices to restrain a proximal end of the stent during delivery. In a first embodiment, a first proximal apex comprises a bore for receiving the trigger wire, and a second proximal apex, disposed adjacent to the first proximal apex, comprises at least one barb. The trigger wire therefore is only coupled to selected ones of the proximal apices. In an alternative embodiment, a first proximal apex comprises a first bore and a second, adjacent proximal apex comprises a second bore, such that a single trigger wire may be disposed through the first and second bores to restrain the first and second proximal apices during delivery.

Stent designs for use with one or more trigger wires

The present embodiments provide an endoluminal prosthesis, such as a stent-graft, having a relatively low delivery profile. In one embodiment, the prosthesis comprises a membrane, and at least one stent having contracted and expanded states, where the stent is coupled to the membrane and maintains patency in the expanded state. The prosthesis further may comprise selectively oriented axial and/or circumferential fibers arranged at predetermined locations along the length and circumference of the prosthesis. An increased population density of the circumferential and/or axial fibers may be provided in areas in which the at least one stent portion is attached to the membrane, or in areas of higher physiological loads imposed upon the endoluminal prosthesis. Selectively orienting axial fibers and circumferential fibers at predetermined locations along the length and circumference of the prosthesis, but not continuously along the entire prosthesis, significantly reduces delivery profile due to the reduction in graft material.

Medical prostheses having bundled and non-bundled regions

The present embodiments provide a stent for use in a medical procedure that comprises a series of proximal apices disposed at a proximal end of the stent and a series of distal apices disposed at a distal end of the stent. In a first embodiment, a first proximal apex comprises a bore for receiving a trigger wire, and a second proximal apex, disposed adjacent to the first proximal apex, comprises at least one barb. In an alternative embodiment, a first proximal apex comprises a first bore and a second, adjacent proximal apex comprises a second bore, such that a single trigger wire may be disposed through the first and second bores to restrain the first and second proximal apices during delivery.

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.

Medical device delivery system and deployment method

A stent graft () for treating Type-A dissections in the ascending aorta () is provided with a plurality of diameter-reducing suture loops (-) operable to constrain the stent graft during deployment thereof in a patient's aorta. The diameter-reducing loops (-) allow the stent graft () to be partially deployed, in such a manner that its location can be precisely adjusted in the patient's lumen. In this manner, the stent graft can be placed just by the coronary arteries () with confidence that these will not be blocked. The stent graft () is also provided with proximal and distal bare stents () for anchoring purposes.

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.
