A method and assembly for forming an occlusion within a vascular cavity. The assembly includes a catheter having an elongate shaft comprising a metallic tubular member extending from a proximal portion to a distal portion of the catheter, a delivery wire including an occlusion member detachably coupled thereto, and a power supply for providing an electrical current to initiate electrolysis at a sacrificial link between the delivery wire and the occlusion member in order to decouple the occlusion member from the delivery wire. The invention also includes a method of positioning and disposing an occlusion member within a vascular cavity using electrolysis, wherein a distal portion of the metallic tubular member serves as a first electrode and the sacrificial link serves as a second electrode. Thus, both the first electrode and the second electrode may be intravenously located proximate a vascular cavity. |
