Abstract

A method and system for treatment of body strictures restores luminal diameter to normal range. The stricture is dilated, stretching its lumen to a desired diameter, collagen is exuded near existing tissue of the stricture and absorbed or adhered to the tissue, making a collagen-enhanced tissue stricture. Energy is emitted to ablate or harden the collagen-enhanced tissue. Treatment may be repeated, creating a hollow, cylindrical supported frame of layers of hardened collagen. Pressure from exuded collagen or from one or more expansion balloons dilates the stricture. The stricture is isolated by balloons at either or both ends of the stricture, isolating the stricture and confining the collagen. Collagen adheres to a stent, preferably tack-welded onto the stricture, which supports the stricture until the stent is absorbed into that tissue.
