Abstract
A fluid delivery system that is implantable in the body for delivering treatment fluids to a person. The delivery system includes a fluid-containing sack positioned in the body which is responsive to internal pressure changes resulting from the breathing pattern of the person. The delivery system also includes a fluid delivery conduit which communicates with the sack through a one-way valve. The conduit is provided for directing treatment fluid out of the delivery system in response to the breathing pattern of a patient and delivering the treatment fluid to a desired region of the person's body in repetitive dosages over a sustained period of time.
