Patent ID: 8475843

Claim:
An implantable or insertable medical device comprising a polymeric matrix, the polymeric matrix comprising a hydrophilic polymer having pendent groups comprising a reacted silyl ether group, the matrix formed from an aqueous composition comprising hydrophilic polymer having the formula: where R 1 comprises an organic side chain group selected from R 2 comprises an amine group; R 2S comprises a silyl ether group; R 10 is independently hydrogen, methyl, or ethyl; and wherein x, y, and z independently represent the amount of each monomer species present in the polymer in random, block, or alternating configuration, with x in the range of 85 mole % to 99 mole %, y in the range of 0 mole % to 14 mole %, and z in the range of 1 mole % to 15 mole %; and wherein the hydrophilic polymer is present at a concentration in the range of 0.1 mg/mL to 50 mg/mL in the aqueous composition.
