A deployment device (100) for deploying an expandable endoluminal prosthesis (200) within a body vessel may include an elongate member extending longitudinally along at least a portion of a length of the deployment device (100). The deployment device (100) may include at least one engagement member coupled to the elongate member and extending outwardly from the elongate member. The deployment device (200) 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 (200), whereby the circumferential trigger wire is removable from between the engagement member and the elongate member.
