Resecting coagulated tissue

Abstract

Abstract This invention is an apparatus and method for quickly and efficiently removing coagulated tissue within a body lumen without affecting the normal, healthy, untreated tissue, to minimize post-operative complications such as bleeding and edema formation. In one aspect, the apparatus features a surgical resection brush assembly (10), including an elongated catheter (18) sized and constructed for delivery through an extended body lumen to a site that has been affected by heat treatment. The assembly (10) further includes a brush formation (12) at the distal end of the elongated catheter (18). The brush formation (12) includes a bristle structure of sufficient stiffness to resect and remove the bodily matter affected by heat treatment without substantially damaging healthy tissue, when the brush formation is actuated relative to the occluded site.
