Claim 17:
18. An implant delivery system comprising:
a delivery pusher including a heater on a distal portion of the delivery pusher;
an embolic coil detachably connected to the delivery pusher;
a monofilament passing through a lumen of the embolic coil and a lumen of the heater;
wherein the monofilament is wrapped around at least one wind of the embolic coil at a first location, wrapped around at least one wind of the embolic coil at a second location, and attached at a third location to the delivery pusher at a location proximal of the heater;
wherein an attachment of the monofilament at the second location isolates different tensions between a proximal portion of the monofilament and a distal portion of the monofilament, and so as to improve breakage upon activation of the monofilament and to resist stretching of the embolic coil.
