Claim 0:
1. A detachment system for delivering an implantable medical device to a target location of a body vessel, the system comprising:
a tubular body comprising a lumen extending therethrough and a compressed distal tube;
a loop wire comprising a first end affixed to the tubular body and comprising a loop opening positioned proximate a distal end of the compressed distal tube; and
a pull wire extending through the lumen and through the loop opening, wherein the pull wire comprises a slack section positioned within the lumen enabling a proximal end of the pull wire to translate proximally and distally independently from a distal end of the pull wire when the detachment system is traversing a microcatheter;
wherein the slack section is a section of stretchable material positioned along a length of the pull wire proximal to a location wherein the loop wire contacts the pull wire;
wherein the pull wire is defined by a proximal rigid section and a distal rigid section and the section of stretchable material is positioned between the proximal rigid section and the distal rigid section, wherein the proximal rigid section and the distal rigid section has a lower degree of elasticity than the section of stretchable material.
