Evaluation of polymer flock and metal alloy intra-tubal device in pigtail monkeys.
Two intratubal devices, one covered with a flock made from ethylene vinyl acetate and the other constructed of titanium-aluminum-vanadium alloy with an etched surface were evaluated after being placed in the Fallopian tubes of pigtail monkeys. In some instances, the devices were medicated with 10% silver nitrate or 50% quinacrine hydrochloride. The microflock device anchored in the tube mechanically, but there is no evidence that either the polymeric or metal alloy device formed an actual attachment with Fallopian tube epithelium. It is suggested that a mechanical design approach to ITDs might be more productive than one which assumes a tissue-device bond.
