Stent and stent-graft designs
First Claim
1. A stent for use in a medical procedure, the stent comprising:
- a series of proximal apices disposed at a proximal end of the stent;
a series of distal apices disposed at a distal end of the stent;
a plurality of strut segments disposed between each proximal apex and each distal apex, where the strut segments enable expansion of the stent from a compressed state to a deployed state, and where adjacent strut segments are joined at a transition region between the proximal and distal apices;
an imaging bore formed in the transition region; and
a first suture bore formed in the transition region and disposed distal to the imaging bore, the first suture bore adapted to receive a suture for coupling a portion of the transition region to a graft material,where a distal region of the stent, including the series of distal apices and a distal portion of the transition region including the first suture bore, overlaps with the graft material,where a proximal region of the stent, including the series of proximal apices and a proximal portion of the transition region including at least one barb, is disposed proximally beyond the graft material, andwhere the imaging bore is disposed at the location corresponding to an endpoint of a proximal edge of the graft material.

Abstract
The present embodiments provide stents and stent-grafts for use in medical procedures. In one embodiment, a stent comprises a series of proximal apices, a series of distal apices, and at least one imaging element. A distal region of the stent, including the series of distal apices and a first suture bore, overlaps with the graft material, while a proximal region of the stent, including the series of proximal apices and at least one barb, is disposed proximally beyond the graft material. In an alternative embodiment, a stent-graft comprises a graft, a first stent and a second stent, in which a series of proximal apices of the first stent are each disposed distal to the proximal end of the graft, and a series of proximal apices of the second stent are each disposed proximally beyond the proximal end of the graft.

8. A stent for use in a medical procedure, the stent comprising:
-
a series of proximal apices disposed at a proximal end of the stent; a series of distal apices disposed at a distal end of the stent; at least one imaging element disposed between the series of proximal apices and the series of distal apices; and a first suture bore disposed in a surface of the stent at a location distal to the imaging element, the first suture bore adapted to receive a suture for coupling a portion of the stent to a graft material, where a distal region of the stent, including the series of distal apices and the first suture bore, overlaps with the graft material, where a proximal region of the stent, including the series of proximal apices and at least one barb, is disposed proximally beyond the graft material, where the distal region of the stent that overlaps with the graft material comprises between about 20 to about 45 percent of the longitudinal length of the stent, while the proximal region that is disposed distally beyond the graft material comprises between about 55 to about 80 percent of the longitudinal length of the stent. - View Dependent Claims (9, 10)
