Abstract: Apparatuses and methods for generating therapeutic compressed acoustic waves (e.g., shock waves) with an improved acoustic wavefront. In the apparatuses, a housing is defined by a chamber and a shockwave outlet, the chamber is configured to be filed with liquid, a plurality of electrodes defining one or more spark gaps and an acoustic reflector can disposed in the chamber, and a pulse generation system configured to apply voltage pulses to the electrodes at a rate of between 10 Hz and 5 MHz. The improved acoustic wavefront is achieved via a free-form acoustic reflector and/or a stable spark gap location. The free-form acoustic reflector is designed according to a disclosed method including iterating reflector shape using spline interpolation based on defined variables. Additionally, a stable spark gap location is achieved via a single servomotor that adjusts both electrodes simultaneously.

Abstract: Embodiments of the present disclosure are directed to methods of inducing therapeutic adipose tissue inflammation using high frequency pressure waves (e.g. high frequency shockwaves) wherein the inflammation results in a reduction in the volume of subcutaneous adipose tissue. Embodiments include applying electrohydraulic generated shockwaves at a rate of between 10 Hz and 1000 Hz to reduce the appearance of cellulite or the volume of subcutaneous fat in a treatment area.

Abstract: Apparatuses and methods for selectively providing laser induced optical breakdown (LIOB) of absorptive targets in biological media. For example, LIOB may be used as part of tissue therapy, such as cosmetic therapy associated with tattoo removal. In some implementation, a system for selectively providing LIOB includes a field generator configured to generate a field and to apply the field through a portion of a biological medium. The system also includes a light source configured to deliver laser light to the portion of the biological medium during application of the field. Application of the field to the biological medium induces movement of free electrons within the portion of the biological medium which may reduce or slow the formation of vacuoles in the biological medium responsive to the laser light.

Abstract: Apparatuses, capacitor arrays, and methods for generating therapeutic compressed acoustic waves (e.g., shock waves). In the apparatuses and at least some of the methods, a plurality of electrodes can disposed in a chamber that is defined by a housing and configured to be filled with liquid, and a plurality of capacitors can be electrically connected to the electrodes and can be carried by (e.g., physically coupled to) the housing.

Abstract: The present invention is designed to be fitted in the upper part of Roll Bars on small vehicles such as quad bikes, ATV's, ride-on mowers, and small tractors (“small vehicles”) to overcome the issue with striking overhanging objects. If the Roll Bar system including the present invention is struck when the vehicle is in forward motion, the present invention allows the upper portion of the Roll Bar to flex, either allowing it to pass under the object or providing a more gradual reduction in speed as opposed to an instant jolt, then returning to the original upright position.
