Abstract

The invention relates to 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 or edema formation. For example, in an aspect, the invention features a surgical resecting brush assembly. The assembly includes an elongated catheter sized and constructed for delivery through an extended body lumen to a site that is occluded with body matter that has been effected by heat treatment and a brush formation near the distal end of the catheter. The brush formation includes a bristle structure of sufficient stiffness to resect and remove the effected bodily matter without substantially damaging adjacent healthy tissue when the brush formation is actuated relative to the occluded site.
