BALLOON CATHETER FOR PHOTODYNAMIC THERAPY

摘要

A balloon catheter has a treatment window which is defined by a reflective coating on each end of the baloon. The catheter has a fibre optic diffusion tip that is longer than the window. The catheter has a clear central channel into which a fibre optic probe can be inserted and an outer sleeve for inflating the balloon near its distal end. The balloon may be of high density polyurethane and the coating of titanium dioxide, silver, gold or aluminium.
