International ClassesA61M 035/00A61B 017/20 AbstractLow frequency ultrasonic pressure waves of high intensity are applied to the skin to cause cavitation. A therapeutic agent may be applied to the skin in a predetermined amount prior to the application of the pressure waves. The therapeutic agent may also be applied to the skin subsequent to the application of the pressure waves. Ultrasonic pressure waves of high frequency which do not cause cavitation may be applied to the skin after delivery of a therapeutic agent. The depth of penetration of the agent may be controlled by varying the burst width of electrical signals applied to a piezoelectric transducer. A housing surrounds the transducer and a sleeve may be provided to define with the housing a predetermined controlled volume chamber for holding a measured amount of agent. An ultrasonic power supply includes means for generating both low and high ultrasonic frequency electric signals, and a switch alternatively connects the high and low frequency signals to the transducer.Field of SearchMEANS FOR INTRODUCING OR REMOVING MATERIAL FROM BODY FOR THERAPEUTIC PURPOSES (E.G., MEDICATING, IRRIGATING, ASPIRATING, ETC.)Infrared, visible light, ultraviolet, X-ray or electrical energy applied to body (e.g., iontophoresis, etc.) With tubular injection means inserted into body With means for cutting, scarifying, or vibrating (e.g., ultrasonic, etc.) tissue CONTROLLED RELEASE THERAPEUTIC DEVICE OR SYSTEM Fluent treating material held in reservoir in hand-supported applicator Having means for varying, regulating, indicating, or limiting injection pressure or aspirating suction Treating material forced into or out of body by self-acting fluid pressure, motor-driven, or mechanical energy storing means (e.g., pressure infusion or aspiration, etc.) LIGHT, THERMAL, AND ELECTRICAL APPLICATION Electrical therapeutic systems Combined with nonelectrical therapy Energy source outside generator body Pulse signal Ultrasonic | |
