1. A membrane for use with an implantable analyte sensor comprising:

  • a first layer comprising a biocompatible polymer composition that is;

    impermeable to immunoglobulins; and

    permeable to oxygen, glucose and lactate; and

    a second layer coupled to the first layer, the second layer comprising a plurality of pores disposed therein and wherein at least one of the plurality of pores disposed in the second layer contains functionalized poly(dimethyl siloxane), functionalized poly(dimethyl siloxane) copolymer or a mixture of functionalized poly(dimethyl siloxane) and functionalized poly(dimethyl siloxane) copolymer of the second layer,wherein the membrane is more permeable to oxygen than glucose and/or lactate.
