Patent ID: 8909339

Claim:
An implantable device to be placed within a blood vessel, comprising: a plurality of conduits configured to allow a part of blood in the blood vessel to flow through the conduits; a plurality of chambers located between said plurality of conduits and configured to collect one or more ingredient of said blood, wherein each of said plurality of chambers is a pillar structure and comprises: a flexible substrate; a first electrode directly disposed on and in contact with the flexible substrate; a film directly disposed on and in contact with the first electrode; and a second electrode directly disposed on and in contact with the film, the film being sandwiched between the first electrode and the second electrode, wherein a combination of the flexible substrate, the first electrode, the film and the second electrode is rolled up as the pillar structure, the second electrode is an outermost layer of the pillar structure surrounding the flexible substrate, the first electrode and the film, and is a porous structure thereby increasing an amount of glucose flowing therethrough, and each of said plurality of chambers is configured to use glucose in said blood to generate a current flowing between the first electrode and the second electrode so as to generate an electric power; and a control unit analyzing said one or more ingredient of said blood collected by said plurality of chambers.
