Abstract: The present disclosure is directed to devices for, and method of, priming the tumor microenvironment with pressure pulses to enhance the efficacy of anticancer therapeutic agents, in a subject in need thereof. Further, increased response of solid tumors locally exposed to stress waves to systemically administered therapeutic agents, is disclosed. The pressure-pulse tumor-priming device comprises: a pulsed laser system (1), a light guide (2) to direct laser pulses to one or more light-to-pressure transducers (3), the one or more light-to-pressure transducers absorbing laser pulses from the pulsed laser system and generating pressure pulses, a tumor-positioning support structure (4) configured to couple one or more light-to-pressure transducers with a solid tumor (5), and a control system (6) to limit the exposure of the solid tumor to the pressure pulses. Anticancer therapeutic agents may be administered before, after or during the priming of solid tumors with pressure pulses.

Abstract: This invention refers to a device capable of rapidly and efficiently converting the energy in a laser pulse into a high-impulse broadband pressure wave and to its applications in the transient permeabilization of a biological membrane, including the outer layers of the skin, without causing damage or discomfort. A method to deliver drugs and biologically active compounds to or through the skin, or biological barriers, with this device is also disclosed.
