Paper Abstract

A simple sealing technique for medical hollow fibers to protect the inner surface from debris or water scattered from targets is proposed. Hollow fibers are sealed with a film of fluorocarbon polymer that was selected from other polymers due to the low absorption and high mechanical strength. The transmission loss of the 20 mm-thick sealing film was 0.2 dB for Er:YAG laser light and the maximum energy density that is capable for the film was 47 J/cm2. We found no damage on the film after a continuous laser-delivery test and a radiation test in running water.
