Fluid delivery system
First Claim
1. A fluid delivery system adapted to be implanted in a body of a patient for delivering treatment fluid to the patient, said delivery system including a fluid-containing sack positioned in the body, said fluid-containing sack is responsive to internal pressure changes resulting from the breathing pattern of the patient, a fluid delivery conduit having a proximal end communicating with the sack and a distal end adapted to communicate with a desired region of the body, said delivery conduit adapted to direct the treatment fluid out of the delivery system into the desired region in response to the breathing pattern of the patient and in repetitive dosages over a sustained period of time, and a one-way valve, said fluid delivery conduit communicating with said sack through said one-way valve.
