Medication 'Robot' Fits Inside Tooth

IntelliDrug is an IST Program project to develop a device for controlled drug delivery that is the size of a tooth (it may be as large as several molars). The IntelliDrug device would be implanted in the mouth of a patient, where it could provide regular, measured doses of medication.

The IntelliDrug micro-system will consist of the following elements:

• a medication release mechanism
• built-in microprocessor for decision-making and dosage program
• micro-sensors capable of determining concentration of selected medications in the blood stream.
• micro-actuators to release standard quantities of medication
• a reservoir for selected medications
• Full dentition (chewing surface) maintained.

The IntelliDrug device will work with a remote control to inform the patient and physician if the drug container needs to be refilled. The medication from the device can either enter the oral cavity and mix with saliva to be swallowed by the patient, or can be administered directly into the patient's bloodstream via the "root" of the tooth.

The IntelliDrug system reminds me of the gas-dispensing tooth from Frank Herbert's 1965 novel Dune. The situation in the novel is complicated; suffice it to say that Dr. Yueh has prepared a means of dispensing a poison gas from an exact duplicate of a tooth.

That peg tooth I put in your mouth after the tumble at Narcal--that tooth must be replaced, in a moment, I'll render you unconscious and replace that tooth." He opened his hand, stared at something in it. "An exact duplicate, its core shaped most exquisitely like a nerve. It'll escape the usual detectors, even a fast scanning. But if you bite down hard on it, the cover crushes.

Not quite the same, since Herbert's idea is obviously for a single-use sytem. But it's still a drug-dispensing tooth.

Take a look at these other medical inventions with a science fiction connection:

• Snake-like Robots For Throat Surgery Doc Ock-Style
  The snakelike robots are highly maneuverable - they can form tight S-curves and have six degrees of freedom.
• World's First Artificial Human Liver Grown In Lab
  Unlike other efforts to grow liver cells, this new technique allows researchers to actually duplicate the structure of the organ.
• PixelOptics SuperVision Optimizes Your Sight
  PixelOptics believes that their SuperVision system can improve anyone's sight to better than 20/20 vision.
