Abstract
A vasoocclusive coil is reinforced with a stretch resistant member to improve safety during retraction of the coil. The stretch resistant member is fixedly attached at one end to the vasoocclusive coil, and the other end of the stretch resistant member is detachably mounted to an elongated pusher member to allow for placement and release of the vasoocclusive coil within the patient's vasculature.
Claims14
An apparatus for release and deployment of a stretch resistant therapeutic device 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;
- a stretch resistant member extending through said lumen of said vasoocclusive coil, said stretch resistant member having a distal end fixedly attached to said distal end of said vasoocclusive coil, and said stretch resistant member having a proximal end looped around and encircling said proximal end of said vasoocclusive coil;
- and
- a severable member detachably connected to said proximal end of said vasoocclusive coil configured to detachably mount said vasoocclusive coil to a distal end of an elongated pusher member to allow for placement of the vasoocclusive coil within the patient's vasculature.
