Abstract
A hydrogel delivery composition, including degradable microcapsules suspended in a degradable thermo-responsive hydrogel. The hydrogel is thermo-responsive at a physiological temperature and changes after application to a more solid state due to body temperatures. The composition includes one or more treatment agents to be released over time as the composition degrades. The composition can be varied to modify the structure and/or release of the treatment agent.
