First Claim
Patent Images
1. An implantable sensor for sensing the presence of an analyte in a vessel, comprising:
- at least two substantially tubular support structures directly connected to one another, for anchoring the sensor in the vessel, each support structure having a side wall with a luminal side facing toward the center of the vessel and an abluminal side facing toward the wall of the vessel;
a sensor housing carried by the support structures, the housing having a streamlined exterior configuration to minimize blood flow turbulence and located between two support structures;
a power supply and electrical circuitry in the housing; and
a sensing surface exposed to the exterior of the housing;
wherein the sensing surface is positioned on the radially inwardly most portion of the luminal side of the housing.

Abstract
A sensor is disclosed, for implantation within a blood vessel to monitor an analyte in blood. In one embodiment, the analyte is glucose. A signal indicative of glucose level is transmitted to an external receiver. The signal may also be used to drive an internal or externally worn insulin pump. Methods are also disclosed.
