  • Novel reverse thermo-sensitive block copolymers
    Publication number: 20080063620
    Abstract: The invention provides a responsive polymeric system, comprising: a polymeric responsive component capable of undergoing a transition that results in a sharp increase in viscosity in response to a change in temperature at a predetermined body site; wherein the polymeric component comprises hydrophilic and hydrophobic segments covalently bound within the polymer component, by at least one chain extender or coupling agent, having at least 2 functional groups; wherein the hydrophilic and hydrophobic segments do not display Reverse Thermal Gelation behavior of their own at clinically relevant temperatures and; wherein the viscosity of the polymeric component increases by at least about 2 times upon exposure to a predetermined trigger.
    Type: Application
    Filed: November 6, 2007
    Publication date: March 13, 2008
    Inventors: Daniel Cohn, Alejandro Sosnik, Michael Kheyfetz
