Abstract

A pump system for the delivery of liquid chemical and biological agents by diffusion from a prepackaged replaceable container into tissue by means of a combination of pressure waves including a base pressure. The pump system comprising a pump having a plurality of pistons driven by actuators, controlled by an electronic controller, at a certain repetition frequency and certain waveforms (up-ramp, peak and downramp) in combination with other signals of acoustic (sonic or ultrasonic) frequencies. The pump system also comprising a cap, in fluid communication with the pump via tubing and pressed against the tissue. The container being placed between the tissue and a membrane within the cap which transmits the pressure waveforms and acts as a piston pushing the agent out of the container and into the tissue. The cap also being capable of transmitting laser pulses to generate heat shock waves in the tissue aiding in the diffusion process in combination with the pressure variations.
