1. An implant delivery device, comprising:
a delivery pusher including a lumen;
an implant detachably connected to the delivery pusher by a tether having a distal end connected to a proximal end of the implant;
an electrical heating element comprised of a coil having a double winding layer;
a fiber optic cable extending through at least a portion of the lumen of the delivery pusher;
a light source in communication with the fiber optic cable;
wherein, in an energized configuration, the fiber optic cable transmits light energy from the light source to the electrical heating element such that the electrical heating element heats and severs the tether.
