Dual capture device for stent graft delivery system and method for capturing a stent graft
First Claim
1. A delivery system for delivering and deploying a stent graft having distal and proximal stents, comprising:
- a) a guidewire catheter having a proximal end and a distal end, and defining an interior extending along a longitudinal axis;
b) a nose cone assembly at the distal end of the guidewire catheter, the nose cone assembly including a nose cone and a distal capture portion proximal to the nose cone, the distal capture portion being movable from a distal capture position to a distal release position by proximal movement of the distal capture portion;
c) a proximal capture portion along the longitudinal axis and proximal to the distal capture portion of the nose cone assembly; and
d) a stent graft including,i) a graft component having a proximal end and a distal end,ii) a proximal stent having proximal apices at the proximal end of the graft component, andiii) a distal stent having distal apices at the distal end of the graft component,wherein the proximal stent is secured to the distal capture portion and releasable by proximal movement relative to the stent graft of the distal capture portion from the distal capture position to the distal release position, and wherein the distal stent is releasably secured to the proximal capture portion.

Abstract
A delivery system for delivering and deploying stents with proximal and distal apices includes a guidewire catheter, a nose cone assembly, a proximal capture portion and a stent graft with proximal and distal stents. The nose cone assembly is at the distal end of the guidewire catheter and includes a nose cone and a distal capture portion. The proximal capture portion is proximal to the distal capture portion of the nose cone assembly. The proximal stent is releasably secured to the distal capture portion and the distal stent is releasably secured to the proximal capture portion. The stent graft can be deployed by releasing the proximal stent and the distal stent from proximal and distal capture portions of the delivery system.

10. A delivery system for delivering and deploying a stent graft having distal and proximal stents, comprising:
-
a) a curved guidewire catheter having a proximal end and a distal end, and defining an interior extending along a longitudinal axis; b) a nose cone assembly at the distal end of the guidewire catheter, the nose cone assembly including a nose cone and a distal capture portion proximal to the nose cone, the distal capture portion being movable from a distal capture position to a distal release position by proximal movement of the distal capture portion; c) a proximal capture portion along the longitudinal axis and proximal to the distal capture portion of the nose cone assembly, the proximal capture portion being movable from a proximal capture position to a proximal release position, and wherein the proximal capture portion and the distal capture portion arcuate actuate independently; and d) a stent graft including, i) a graft component having a proximal end and a distal end, ii) a proximal stent having proximal apices at the proximal end of the graft component, and iii) a distal stent having distal apices at the distal end of the graft component, wherein the proximal stent is releasably secured to the distal capture portion and releasable by proximal movement relative to the stent graft of the distal capture portion from the distal capture position to the distal release position, and wherein the distal stent is releasably secured to the proximal capture portion and is releasable from the proximal capture portion by proximal movement of the proximal capture portion from the proximal capture position to the proximal release position. - View Dependent Claims (11, 12, 13, 14, 15)
