Abstract: The present invention generally relates to systems and methods for stimulating tissue using focused energy. In certain embodiments, the invention provides a system for stimulating tissue that includes a first energy source, a second energy source, and a focusing element that focuses at least the first or second energy source so that the first and second energy sources target the same region of tissue such that the combined effect stimulates the tissue.

Abstract: The invention generally relates to apparatuses and methods for stimulating and monitoring biological tissue. In certain aspects, the invention provides a system for stimulating and monitoring tissue, the system including a first energy source, a second energy source, and an imaging device, in which the system is configured such that the first and second energy sources target the same region of tissue and the combined effect of the first and second energy sources stimulates the region of tissue.

Abstract: An apparatus for generating focused currents in biological tissue is provided. The apparatus comprises an electric source capable of generating an electric field across a region of tissue and means for altering the permittivity of the tissue relative to the electric field, whereby a displacement current is generated. The means for altering the permittivity may be a chemical source, optical source, mechanical source, thermal source, or electromagnetic source.

Abstract: The invention generally relates to methods for treating osteoarthritis. In certain embodiments, methods of the invention involve providing stimulation to a subject's central nervous system to modulate a signal sent to or from the subject's joint, thereby treating osteoarthritis.

Abstract: An apparatus for interfacing between tissues being stimulated is provided. The apparatus includes an electric source capable of generating an applied electric field across a region of tissue and/or a means for altering at least one electromagnetic characteristic of the region of tissue relative to the applied electric field and an interface component, such interface component creating an interface between the region of tissue and the applied electric field or the means for altering at least one electromagnetic characteristic of the region of tissue.
