Circumferential trigger wire for deploying an endoluminal prosthesis

摘要

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.

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.
