Abstract
Abstract A medical device is disclosed which includes a deformable electrode device. In one illustrative embodiment, the deformable electrode is in the form of a braided member, at least a portion of which is electrically conductive. The braided member is extended over an elongated inner member, such as a guide wire, catheter shaft, or the like. A proximal sheath is slidably extended over the inner member and is connected to the braided, electrically conductive member. The proximal sheath may be advanced distally to deform the braided member so that it defines a distally facing, ablative ring, and is operative to form an annular lesion.
