Patent ID: 8029467

Claim:
An apparatus for release and deployment of a stretch resistant therapeutic device within a patient's vasculature, comprising: a vasoocclusive coil having a proximal end and a distal end, said vasoocclusive coil defining a lumen having a length between said proximal and distal ends; an elongated pusher member having a distal end adjacent to said proximal end of said vasoocclusive coil; a connector fiber detachably mounting the vasoocclusive coil to the pusher member for placement of the vasoocclusive coil within the vasculature, wherein said connector fiber can be severed by heating of the connector fiber; a loop attached at the proximal end of the coil, said loop detachably connected to said connector fiber at the distal end of the pusher member; a stretch resistant member extending throughout the length of said lumen of said vasoocclusive coil, said stretch resistant member having a first end and a second end, said first end of said stretch resistant member being fixedly attached to the distal end of said vasoocclusive coil, and said second end of said stretch resistant member being detachably connected to said connector fiber; and an electrical resistance heater wire disposed adjacent to said connector fiber, said electrical resistance wire being connected to a control unit for heating and thereby severing said connector fiber.
