The new improved silastic band for ligation of fallopian tubes

Twelve different sizes of elastic bands were tried in animal experimentation for tubal sterilization. Reversible sterilization was not successful in any of the animals after removal of the various-sized bands. A new elastic Silastic band is reported which is larger and wider than those previously described. Over a 4-year period, no serious complications have been reported and extremely low pregnancy rates have been achieved by utilizing the new, wider bands and our applicators for human sterilization.
