1. An implantable sensor for use in measuring a concentration of an analyte in a bodily fluid, the sensor comprising:

  • a sensor body comprising a sensing region adapted for transport of an analyte thereto, and a porous biointerface material that covers at least a portion of the sensing region, wherein the porous biointerface material covering the portion of the sensing region supports tissue ingrowth, wherein the sensing region is located on a curved portion of the body such that when a foreign body capsule forms around the sensor, a contractile force is exerted by the foreign body capsule toward the sensing region, wherein the body comprises a first surface on which the sensing region is located and a second surface, and wherein said first surface comprises an anchoring material thereon for supporting tissue ingrowth and wherein said second surface is located opposite said first surface, and wherein said second surface is substantially smooth and comprises a biocompatible material that is non-adhesive to tissues.
