Claim 7:
8. A detachment system for delivering an implantable medical device to a target location of a body vessel, the system comprising:
a pull wire extending through a tubular body of the detachment system; and
a loop wire looped over the pull wire at a distal end of the loop wire, wherein the pull wire comprises a slack section positioned proximal to a loop opening in the loop wire, the slack section being effective to inhibit premature detachment of the implantable medical device by inhibiting movement of 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 comprise a lower degree of elasticity than the section of stretchable material.
