Patent ID: 8376996

Claim:
A stretch resistant therapeutic device for release and deployment within a patient's vasculature from an elongated pusher member, comprising: a vasoocclusive coil having a proximal end and a distal end, said vasoocclusive coil defining a lumen between said proximal and distal ends, and said vasoocclusive coil including a displaced coil segment at the proximal end of the vasoocclusive coil; a severable member configured to be connected to an elongated pusher member, said severable member forming a loop extending through said displaced coil segment; and 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 detachably mounted at the second end to said severable member to allow for placement of the vasoocclusive coil within the patient's vasculature.
