OPTIMIZED SENSOR GEOMETRY FOR AN IMPLANTABLE GLUCOSE SENSOR
First Claim
1. An implantable sensor for use in measuring a concentration of an analyte in a bodily fluid, the sensor comprising:
- a substantially cylindrical body comprising a sensing region and adapted for transport of at least one analyte from a bodily fluid to the sensing region, wherein the substantially cylindrical body is defined by a curved lateral surface and two ends, and wherein the sensing region is located on the curved lateral surface such that when a foreign body capsule forms around the sensor in vivo, a contractile force is exerted by the foreign body capsule toward the sensing region.

Abstract
An implantable sensor for use in measuring a concentration of an analyte such as glucose in a bodily fluid, including a body with 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 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. The body is partially or entirely curved, partially or entirely covered with an anchoring material for supporting tissue ingrowth, and designed for subcutaneous tissue implantation. The geometric design, including curvature, shape, and other factors minimize chronic inflammatory response at the sensing region and contribute to improved performance of the sensor in vivo.
