Patent ID: 7572246

Claim:
A stretch resistant therapeutic device for release and deployment within a patient's vasculature, comprising: a vasoocclusive coil having a proximal end and a distal end, said vasoocclusive coil defining a lumen between said proximal and distal ends; a stretch resistant member extending through said lumen of said vasoocclusive coil, said stretch resistant member having first and second ends, said stretch resistant member being fixedly attached at the first end to said vasoocclusive coil and permanently bonded at the second end to an elongated pusher member to allow for placement of the vasoocclusive coil within the patient's vasculature; and means for severing said stretch resistant member disposed adjacent to said stretch resistant member to cause the stretch resistant member to release the vasoocclusive coil for deploying the vasoocclusive coil from the pusher member when a desired placement of the vasoocclusive coil within the vasculature is achieved.
