A catalyst is disclosed for the polymerization and co-polymerization of olefins with functionalized monomers. The device includes an attachment mechanism for direct attachment to the catheter at a location proximal to a treatment device positioned on the catheter, the attachment mechanism having a proximal end, a distal end, and a longitudinal axis extending from the proximal end to the distal end. The method may include using the apparatus to subject the tissue near the body passageway to a plurality of energy treatment cycles.
