ABSTRACT:
A device and method for precise placement of a medical instrument for fluid delivery at, or withdrawal of fluid from, a predetermined location in a body is disclosed. A sensor, such as a proximity detector or electrically conductible circuitry, is implanted into the body adjacent to a predetermined location, which location preferably has an implanted reservoir thereat, for sensing the position of a medical instrument having an open end portion inserted into the reservoir to enable delivery of medicament into the reservoir or, in the alternative, to remove fluid from the reservoir. A signal indicative at least of a sensed desired positioning of the instrument is generated and used to assure that the instrument has been properly positioned, with additional circuitry also being provided to enable location of the implanted reservoir for positioning of the instrument prior to insertion into the body.
