An interferential current system for performing a therapeutic procedure includes a controller, a stimulation power supply and at least one sensor providing patient derived sensor feedback to the controller. The system also includes at least two electrodes disposed on an epidermis of the patient and arranged to supply transcutaneous electrical impulses to a therapeutic target area when supplied power by the stimulation power supply. The electrodes supply impulses at two different frequencies, giving rise to at least one beat impulse having an interference frequency. The controller generates a patient specific model based at least in part on the sensor feedback, the patient specific model indicative of at least one of: electrode placement appropriate for the transcutaneous electrical impulses to reach the therapeutic target area, appropriate magnitudes of the at least two different frequencies, appropriate magnitude of the interference frequency, and appropriate sweep frequencies.

A medical wound covering for controlling blood flow includes a flexible sheet for covering or surrounding the anatomical site of a wound, such as a surgical drape. The flexible sheet includes a plurality of electrodes electrically connectible to a stimulation power supply. Upon receipt of power from the stimulation power supply, the electrodes supply electrical impulses to the anatomical site of the wound in order to stem or arrest undesired bleeding. In some cases, the stimulation power supply is an interferential therapy power supply, and a pair of electrodes supplies electrical impulses at two different frequencies, the electrical impulses provided at two different frequencies giving rise to at least one beat impulse having an interference frequency. The beat impulse activates the sympathetic nerves to induce vasoconstriction in the local blood vessels. Alternatively, the beat impulse can be programmed to target the parasympathetic nerves if vasodilatation is desired.

An interferential current system for cardiac treatment of a patient, includes a controller, a stimulation power supply and a plurality of electrodes. The electrodes supply transcutaneous electrical impulses when supplied power by the stimulation power supply, the plurality of electrodes including at least two electrodes supplying transcutaneous electrical impulses at two different frequencies, the transcutaneous electrical impulses provided at two different frequencies giving rise to at least one beat impulse having an interference frequency. At least one sensor in communication with the controller provides data to the controller indicative of various cardiac pathologic conditions, including but not limited to, rhythm abnormalities, muscle wall contraction abnormalities, and ischemic heart disease abnormalities of the patient. At least one of a timing and an intensity of the transcutaneous electrical impulses is varied by the controller based at least in part upon the data indicative of the aforementioned cardiac pathologies of the patient.

When transducer arrays (i.e., arrays of electrode elements) are used to apply alternating electric fields to a subject's body, the subject may experience electrosensation. This electrosensation can be ameliorated by changing the way the voltage ramps up from zero to its peak when the AC voltage is first applied to any given transducer array, and also when the alternating electric field switches direction.

Provided herein are methods of generating a biologically effective unipolar nanosecond electric pulse by superposing two biologically ineffective bipolar nanosecond electric pulses and related aspects, such as electroporation and/or therapeutic applications of these methods to non-invasively target electrostimulation (ES) selectively to deep tissues and organs.

Ultrasound (US) apparatus and method for applying low energy US onto an internal tissue/organ, including a non-invasive US appliance used on a treatment region over the internal tissue/organ, and an electrical stimulation apparatus for simultaneously inducing interferential electrical stimulation. A controller controls parameters of the electrical stimulation apparatus and the US appliance, and dynamically changes at least one of the parameters, for maintaining the impedance of the body tissue in the treatment region within an impedance range. The US apparatus includes an impedance monitoring apparatus for continuously measuring, tracking, and monitoring impedance in the treatment region, wherein the controller dynamically changes at least one of the parameter in response to the impedance as monitored, for maintaining the impedance within the predefined range. The internal tissue/organ can be a female fertility organ which can be an ovarian follicle, a blood vessel of the uterus (womb), the ovary, the endometrial lining, and the Fallopian tube; a lung, a pulmonary organ, an adipose tissue, ulcer, closed wound, internal injury, inflammation. and nerves.

A device covering for controlling blood flow includes a cuff configured to be mounted to an extremity of a patient. The cuff includes a plurality of electrodes electrically connectible to a stimulation power supply. Upon receipt of power from the stimulation power supply, the electrodes supply electrical impulses to the anatomical site in order to stem or stop blood flow. In some cases, the stimulation power supply is an interferential therapy power supply, and a pair of electrodes supplies electrical impulses at two different frequencies, the electrical impulses provided at two different frequencies giving rise to at least one beat impulse having an interference frequency. The beat impulse activates the sympathetic nerves to induce vasoconstriction in the local blood vessels. Alternatively, the beat impulse can be programmed to target the parasympathetic nerves if vasodilatation is desired.

A stimulator and a method using electrical stimulation of a spinal cord, for providing positive regulation of multiple symptoms other than pain is disclosed. An example method includes positioning a first pair of implantable electrodes to a dura matter in an epidural space proximate to a subject's spinal cord at predetermined locations, positioning a second pair of implantable electrodes to the dura matter in the epidural space proximate to the subject's spinal cord at predetermined locations, and transmitting signals of first and second frequencies through the first and second pairs of implantable electrodes respectively, so that the signals of the first and second frequencies interfere with each other to produce at least one beat signal proximate to the subject's spinal cord. The at least one beat signal has a frequency within a range of more than 250 Hz to about 15,000 Hz.

The present invention promotes the activation of various physiological functions according to the stimulation of the body by superimposing a reference wave microcurrent of a low frequency and a main wave microcurrent of a high frequency into a preset pattern, or by additionally superimposing a multiple superimposed wave microcurrent discretely having a frequency of a larger magnitude sequentially than the main wave microcurrent and applying it to living organisms, and enables that the use and expandability can be increased by providing an additional configuration in which a multifunctional portable housing that can select AC electric stimulation and DC electric stimulation is worn on the wrist of the human body, thereby enabling the application of an electrical stimulation tailored to the body or disease/health condition of a user.
