Abstract
Disclosed are apparatus and methods for aiding thrombosis through the application of electric potential. In one embodiment, a hollow prosthesis is placed within a patient at a treatment site, such as at an aneurysm. The outer surface of a prosthesis is given a positive charge. The positive charge on the outer surface attracts negatively charged components of blood, thus facilitating the repair of perigraft flow. In another embodiment, a conductive wire is used to pierce a graft and enter an aneurysm sac. The wire is positively electrically charged to aid in thrombosis, thus facilitating the repair of perigraft flow.
