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, 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;
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 a graft component having a proximal end and a distal end, a proximal stent at the proximal end of the graft component and a distal stent at the distal end of the graft component, wherein the proximal stent is radially constrained from within the stent graft by the distal capture portion and 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.

12. A method of deploying a stent graft from a stent graft delivery system to thereby implant the stent graft intravascularly within a patient, comprising the steps of:
-
a) releasing a proximal stent at a proximal end of a stent graft from a distal capture portion of a nose cone assembly fixed to a distal end of a guidewire catheter of a delivery system, while the stent graft is positioned at a treatment site within a blood vessel of a patient, the distal capture portion being moveable by proximal movement of the distal capture portion from a capture position to a release position; and b) releasing a distal stent at a distal end of the stent graft from a proximal capture portion of the delivery system, thereby deploying the stent graft from the delivery system and implanting the stent graft intravascularly within the patient. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. 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 capture position to a 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, wherein the proximal capture portion and the distal capture portion arcuate 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 secured to the distal capture portion and releasable by proximal movement of the distal capture portion from the capture position to the 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 capture position to the release position.
