Abstract:
1. An embolization delivery system used by a physician to deliver an embolization coil into the vasculature of a patient; the embolization delivery system comprising: a delivery catheter inserted into the vasculature of the patient; a delivery tube having a proximal end and a distal end, the delivery tube selected as one from the group of a catheter and a wire guide, the distal end of the delivery tube capable of being inserted into the delivery catheter; a connector having a proximal portion and a distal portion; the proximal portion being disposed around and permanently coupled to the distal end of the delivery tube; a detachable embolization coil having a distal end and a proximal end; the proximal end of the coil being disposed within the distal portion of the connector and held in place by compressive forces exerted by the connector; and a release mechanism for detaching the embolization coil, the mechanism comprising a wire having a first end, a middle portion, and a second end, the first end being coupled to the distal end of the delivery tube, the middle portion being in contact with the distal portion of the connector and the proximal end of the coil; the wire positioned so that its second end may be manipulated in a predetermined manner by the physician through the proximal end of the delivery catheter; wherein manipulation of the second end of the wire causes the middle portion to split part of the connector, thereby, reducing the compressive forces exerted by the connector onto the embolization coil and allowing the coil to detach from the embolization delivery system.
