1. A delivery member for delivering an implantable medical device to a target location of a body vessel, the delivery member comprising:
a body comprising a lumen extending therethrough, a compressed distal portion, and a support coil inner tube;
a pull wire extending through the lumen, the pull wire comprising a pull wire portion that extends radially to abut a sidewall of the support coil inner tube thereby providing frictional resistance against the support coil inner tube;
wherein the pull wire is positioned to secure the implantable medical device to the delivery member,
wherein the pull wire portion is effective to inhibit premature detachment of the implantable medical device by inhibiting proximal translation of the pull wire due to the frictional resistance provided by the pull wire portion against the support coil inner tube;
wherein the pull wire comprises a slack length at a proximal end of the pull wire and a straight portion distal of and approximate the slack length,
wherein a distal end of the pull wire comprises a straight portion, and
wherein the pull wire portion is proximal of and approximate the straight portion of the distal end of the pull wire.
