Abstract

A responsive polymeric system including a responsive polymeric component capable of undergoing a transition that results in a sharp increase in viscosity in response to a triggering effected at a predetermined body site. The system includes a solid non-ceramic reinforcing component which reinforces the polymeric component, and an aqueous-based solvent wherein the viscosity of the responsive polymeric component increases by at least about 2 times upon exposure to a predetermined trigger.
