1. A blood glucose detector for implantation within a blood vessel, comprising:a support, having a first side for contacting the wall of the vessel and a second side for facing radially inwardly toward the center of the vessel, wherein the support comprises an enlargeable frame and an expandable tubular body; and a sensor carried by the support and having a sensing surface thereon, wherein the sensing surface is spaced radially inwardly from the first side by a distance of at least about 0.2 mm, such that the velocity of blood in the vessel inhibits obstruction of the sensing surface; and a tubular sheath on the tubular body, wherein the sheath is on the radially inwardly facing surface of the tubular body.
