Circumferential trigger wire for deploying an endoluminal prosthesis

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 at least one circumferential trigger wire aperture in the trigger wire guide;
• an expandable endoluminal prosthesis positioned on the deployment device;
• 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 circumferential trigger wire aperture and exiting the trigger wire guide and at least partially encircling the prosthesis, the circumferential trigger wire engaged by the axial trigger wire and restraining at least a portion of the prosthesis in a compressed configuration.
