Abstract
A biodegradable biodelivery device is disclosed. The biodelivery device is formed from a polymer comprising the reaction product of a polyol and a polyacid. When exposed to water, the polymer degrades through hydrolysis. Of particular advantage, the polymer can be formed so as to be elastic and flexible. In one embodiment, the polymer is formed into a vaginal insert. As the polymer degrades, the polymer releases acid to a vaginal environment for decreasing the pH of the environment.
