Systems and methods for inhibiting premature embolic implant deployment

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 plurality of pull wire portions that each extend 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 plurality of pull wire portions are 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 plurality of pull wire portions against the support coil inner tube.
