[0001] All or a portion of a surface of an implantable sensor is covered with a biocompatible coating formed at least partially of a biomaterial matrix having properties that promote a substantially even growth of tissue cells over the surface of the coating. Additional materials, such as growth factors, agents that recruit endogenous stem cells, and cell adhesion motif arginine, glycine, aspartic acid may be included in the coating. Autologous cells may be added to the coating prior to implantation. The sensor surface may also be textured, by etching or abrading, in order to promote even tissue growth. Alternatively, the sensor surface may be covered with a coating having properties that inhibit the growth of tissue. These coatings may include a biomaterial, a biomaterial matrix having a drug, such as a sirolimus or a steroid, an active component, or a self assembled monolayer. |
