Patent ID: 8376995

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, said vasoocclusive coil including a loop attached at the proximal end of the coil; a connector fiber configured to be fixedly attached to an elongated pusher member, said connector fiber forming a connector fiber loop extending through said loop attached at said proximal end of said coil, wherein said connector fiber can be severed by heating of the connector fiber; a stretch resistant member forming a stretch resistant loop extending throughout the length of said lumen of said vasoocclusive coil, said stretch resistant loop having a first end and a second end, said first end of said stretch resistant loop being fixedly attached to the distal end of said vasoocclusive coil, and said second end of said stretch resistant loop extending through said connector fiber loop; 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.
