Patent ID: 7452377

Claim:
A biomedical implant comprising a polymer that is cured from a composition comprising a random or block macromonomer of general formula: wherein L is a spacer group; Z is a crosslinkable group and the macromonomer contains at least one pendant Z; each R 1 is independently C 1 to C 6 alkyl or perfluorinated C 1 to C 6 alkyl; each R 2 is independently an R 1 or L-Z group; the molar percentage of: n is from 50 up to but not including 100%; m is from 0 to 10%; o is from 0 to 50%; p is from 0 to 2%, and o+p=0 when L or R 1 contain fluorine; q is from 0 to 2%; s is from 0 to 2%; the molecular weight of the macromonomer being more than 3,000; and wherein the macromonomer is curable in vivo and when polymerized to form the cured polymer, the polymer has a shear modulus as measured by a Micro Fourier Rheometer between 0.1 and 5 kPa.
