Patent ID: 8597323

Claim:
An implant delivery system comprising: a delivery pusher; an implant device detachably connected to the delivery pusher by a tether having a distal end connected to a proximal end of the implant device, wherein the tether is substantially non-tensioned when connecting the implant device to the delivery pusher; and an electrical heating element comprising: an electric coil having a heat-generating zone, the coil being operable to achieve a temperature in the heat-generating zone that is sufficient to sever the tether; the coil configured coaxially about at least a portion of the tether; the electric coil comprising: a plurality of windings, at least one which is wound in a reverse direction over the other windings to form a coil region having two winding layers; wherein heat generated by the heating element severs the tether at a point near the distal end of the tether.
