Abstract:
1. An apparatus for release and deployment of a stretch resistant therapeutic device within a patient's vasculature, comprising: an elongated flexible tubular catheter having a frustoconically shaped distal tip; a vasoocclusive coil having a proximal end and a distal end, said vasoocclusive coil defining a lumen between said proximal and distal ends; and a stretch resistant member having a proximal end and a distal end, said stretch resistant member extending through said lumen of said vasoocclusive coil, said stretch resistant member being fixedly attached at said distal end of said stretch resistant member to said distal end of said vasoocclusive coil and not fixedly attached at said proximal end of said stretch resistant member to said vasoocclusive coil, and said stretch resistant member being configured to be mechanically releasably mounted to the distal end of said distal tip of said elongated flexible tubular catheter by a tubular distal tip mounted to an outer surface of said frustoconically shaped distal tip of said elongated flexible tubular catheter, said tubular distal tip having a frustoconical shape and formed of a yieldable material configured to releasably hold the proximal end of said stretch resistant member to allow for placement of the vasoocclusive coil within the patient's vasculature.
