Optimized sensor geometry for an implantable glucose sensor

A wholly implantable sensor adapted to measure a concentration of an analyte in a bodily fluid, comprising:

• a wholly implantable body comprising a sensing region adapted for transport of analytes between the sensor and the bodily fluid, wherein the sensing region is located on a curved portion of a first major surface of said body, wherein the body further comprises a second major surface, wherein the sensing region is situated at a position on said first major surface offset from a center point of said first major surface, wherein the sensor is a subcutaneous sensor suitable for implantation in a soft tissue of a body, and wherein said first surface comprises a porous material thereon for supporting tissue ingrowth.

An implantable sensor adapted to measure a concentration of an analyte in a bodily fluid, comprising:

• a body having a first major surface and, opposite thereto, a second major surface, wherein the first major surface is generally planar, slightly convex, and has rounded edges, with a sensor region located on the first major surface that is spaced away from the rounded edges and offset from a center point of said first major surface, wherein the first major surface is sufficiently convex that when a foreign body capsule forms around the sensor, contractile forces are exerted thereby generally uniformly towards the sensing region, and wherein the sensor is a subcutaneous sensor suitable for implantation in a soft tissue of a body.
