Circumferential trigger wire for deploying an endoluminal prosthesis
First Claim
1. An expandable endoluminal prosthesis and deployment device for deploying the expandable endoluminal prosthesis within a body vessel, the deployment device comprising:
- an elongate member extending longitudinally along at least a portion of a length of the deployment device;
an expandable endoluminal prosthesis disposed about the elongate member and having an exterior circumference;
at least one axial trigger wire coupled to the elongate member and extending outwardly from the elongate member; and
a circumferential trigger wire extending out of a first circumferential trigger wire aperture of the elongate member, forming a single loop circumferentially around substantially the entire exterior circumference of the expandable endoluminal prosthesis and re-entering an axially spaced second circumferential trigger wire aperture in the elongate member, the single loop removably received under the axial trigger wire between the axial trigger wire and the elongate member;
wherein the circumferential trigger wire is manipulatable from a distal end of the deployment device, whereby the circumferential trigger wire is removable from between the axial trigger wire and the elongate member.

Abstract
A deployment device for deploying an expandable endoluminal prosthesis within a body vessel may include an elongate member extending longitudinally along at least a portion of a length of the deployment device. The deployment device may include at least one engagement member coupled to the elongate member and extending outwardly from the elongate member. The deployment device may include a circumferential trigger wire extending at least partially circumferentially around the elongate member and removably received between the engagement member and the elongate member. The circumferential trigger wire may be manipulatable from a distal end of the deployment device, whereby the circumferential trigger wire is removable from between the engagement member and the elongate member.

10. A system comprising:
-
a deployment device comprising a tubular trigger wire guide, at least one axial trigger wire aperture in the trigger wire guide, and first and second axially spaced circumferential trigger wire apertures in the trigger wire guide; an expandable endoluminal prosthesis positioned on the deployment device and having an exterior circumference; at least one axial trigger wire received within the trigger wire guide, the axial trigger wire extending through the axial trigger wire aperture and exiting the trigger wire guide; and a circumferential trigger wire received within the trigger wire guide, the circumferential trigger wire extending through the first circumferential trigger wire aperture and exiting the trigger wire guide and encircling the prosthesis substantially about the entire exterior circumference of the prosthesis forming a single loop and re-entering the trigger wire guide at the second circumferential trigger wire aperture, the single loop of the circumferential trigger wire passing beneath the axial trigger wire such that the circumferential trigger wire is engaged by the axial trigger wire and restrains at least a portion of the prosthesis in a compressed configuration. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method of deploying an expandable endoluminal prosthesis, the method comprising:
-
providing a deployment device comprising a tubular trigger wire guide, at least one axial trigger wire aperture in the trigger wire guide, an axial trigger wire received within the trigger wire guide and extending through the axial trigger wire aperture such that a curve of the axial trigger wire is disposed external of the trigger wire guide, a prosthesis disposed about the trigger wire guide having an exterior circumference, and a circumferential trigger wire exiting a first circumferential trigger wire aperture in the trigger wire guide, forming a single loop about substantially the entire exterior surface of the prosthesis and re-entering the trigger wire guide at an axially spaced second circumferential trigger wire aperture, the single loop passing beneath the axial trigger wire and manipulating the circumferential trigger wire from a distal end of the deployment device, and sliding the circumferential trigger wire out of engagement between the curve of the axial trigger wire and an outer surface of the trigger wire guide.
