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.
Appareil et procédé d'élimination rapide de tissus coagulés d'un orifice corporel sans affecter les tissus normaux et sains non traités, ce qui réduit les complications postopératoires telles que les saignements et les oedèmes. Dans l'une de ses variantes, l'appareil comporte une brosse chirurgicale de résection (10) comprenant un cathéter allongé (18), dimensionné et conçu pour accéder à travers une ouverture corporelle allongée à un site ayant été soumis à un traitement thermique. L'ensemble (10) comprend par ailleurs une brosse (12) située à l'extrémité distale du cathéter allongé (18), et qui comporte une structure de soies d'une dureté suffisante pour assurer la résection et l'élimination des matières corporelles soumise au traitement thermique sans pratiquement causer de dommages aux tissus sains lorsque la brosse est en mouvement par rapport au site occlu.
