Abstract
A method of delivering a therapeutic agent by providing a cross-linked polymer encapsulating the therapeutic agent to a site in a patient. The degradation rate of the cross-linked polymer is correlated with a local concentration of an indicator, and the therapeutic agent is released as the cross-linked polymer degrades.
