Abstract

A minivalve for delivering one of a control solution or a drug solution to a point of interest in a freely moving animal. The minivalve is portable by the freely moving animal, such as a mouse, rat, or primate, on its head without interfering with its behavior. The minivalve having an input for a control solution and an input for a drug solution and further having a common output for outputting either of the control solution or drug solution to an input of a microdialysis probe implanted at a point of interest in the animal. Also provided are systems for delivering one of a control solution or a drug solution to a point of interest in the animal. The system comprises the minivalve, a drug ejection device such as a microdialysis probe or injection cannula implanted at the point of interest in the small animal, and a microelectrode placed adjacent to the drug ejection device. The minivalve is designed to be easily modified to be actuated with a gas or liquid, to be used in larger animals and in humans, to be mounted on body parts other than the head, to be used for drug delivery into other body organs than the brain, and to be integrated into various industrial/scientific instruments.
