A stimulation device includes an energy source; an electronics unit; an actuator that is coupled with the electronics unit and/or the energy source. The electronics unit includes a controller. The energy source, the electronics unit and the actuator are arranged in a housing. A fixing unit which is coupled with the housing and affixes the stimulation device on a heart or in a heart. The actuator emits electromagnetic waves for the stimulation of genetically manipulated tissue, and the controller controls the stimulation of the tissue by way of the electromagnetic waves of the actuator.

In one aspect, a method is provided for performing light therapy on a subject. The method comprises providing a device which emits electromagnetic radiation that oscillates between at least first and second distinct polarization states; and illuminating the subject with the emitted electromagnetic radiation. In another aspect, a fixture is provided which comprises a first source of electromagnetic radiation which emits electromagnetic radiation in a first polarization state; a second source of electromagnetic radiation which emits electromagnetic radiation in a second polarization state which is distinct from said first polarization state; and an oscillator which oscillates electromagnetic radiation output by the fixture between at least said first and second polarization states.

A dermatological phototherapy device, system, and method, including a light emitting device configured and arranged to emit light from a bottom surface thereof; and an attachment portion having an aperture therethrough configured to permit light through. The attachment portion is configured to retain the device to a user's skin using a circumferential silicone skirt and bathe the skin with phototherapeutic light from the light emitter. Attachment of the device may be preceded with the application of synergistic fluid, ointment, gel, cream, lotion, foam, soap, or other solutions which may or may not consist of known topical treatment agents, augment device attachment to the skin, and/or have photodynamic properties. The light emitted may be any wavelength, combinations of wavelengths, intensity, pulse frequency, and exposure duration.

Devices and methods for impinging light on tissue to induce one or more biological effects, and more particularly illumination devices and related methods that may be used for intranasal delivery of irradiation are disclosed. Exemplary illumination devices may include a light guide that is optically coupled with a light source, where the light guide may be configured for insertion along one or more intranasal passageways. In this manner, the light guide may provide irradiation of light to tissues along or near the upper respiratory tract to prevent and/or treat various infections and other tissue conditions thereof. Light guides may include flexible materials with suitable dimensions and/or shapes that allow the light guides to follow variable paths of intranasal passageways during use.

A system for for treatment of wounds consists of a treatment housing, a fluid delivery mechanism for supplying debridement fluids to the wound treatment area, an evacuation mechanism for evacuation of debris from the treatment chamber. A handheld device is connected to the treatment housing, wherein its interior accommodates a laser source, a scanning device, an image recording device and at least one sensors/detectors, a control unit having a microprocessor for controlling operation of the system. The sensors detect concentration of various substances in the wound, and microprocessor analyzes data obtained by the sensors and generates signals to adjust parameters of the laser, the liquid dispensing nozzles and the suction outlet to optimize removal of necrotic tissue so as to ultimately to promote wound healing.

In accordance with various aspects of the present teachings, systems and methods for applying treatment energy, e.g., electromagnetic radiation such as laser radiation in the visible and near infrared wavelengths, to body areas having bulges and fat deposits, loose skin, pain, acne and/or wounds. In some aspects, the systems and methods can enable relatively lengthy treatments to be performed by having the practitioner set-up and/or start the treatment, thereafter allowing the treatment to proceed safely and effectively without the continued presence of the practitioner.

An arrangement for providing retinal ERG stimulus and heating, the arrangement comprising at least one processor (102) and at least one light source (LEDS) for providing at least a stimulus beam to induce an ERG signal from a target area of the retina, the arrangement additionally comprising a heating system (LF) for elevating the temperature of at least the target area, wherein the processor (102) is configured to receive a retinal ERG signal induced by the stimulus beam during retinal heating, determine, based on said ERG signal, one or more indicators being indicative of a temperature of the retina, and control the heating system (LF) based on said indicator.

An unattended approach can increase the reproducibility and safety of the treatment as the chance of over/under treating of a certain area is significantly decreased. On the other hand, unattended treatment of uneven or rugged areas can be challenging in terms of maintaining proper distance or contact with the treated tissue, mostly on areas which tend to differ from patient to patient (e.g. facial area). Delivering energy via a system of active elements embedded in a flexible pad adhesively attached to the skin offers a possible solution. The unattended approach may include delivering of multiple energies to enhance a visual appearance.

Light energy is applied externally to a patient's head, neck, or both, to treat the brain and nervous system. The light energy stimulates different neurological pathways, reduces inflammation, stimulates mitochondria function in the brain, and increases HRV. The light is applied to the patient on the skull, near the vagus nerve, or a combination thereof. The treatment can be enhanced by activating the cranial nerves while the light is applied. The wavelengths of the applied light range from ultraviolet to far infrared, and preferably are visible light from about 400-760 nm. In a preferred embodiment the applied light is in the red range and more preferably about of 635 nm±10 nm. The applied light energy is applied with a pulse frequency or frequencies that mimic healthy brain function of alpha, beta, delta, and theta waves such as 8 Hz, 53 Hz, 73 Hz and 101 Hz. The pulse frequencies can be applied singularly, serially, alternately, or simultaneously. This low-level light therapy has an energy dose rate that causes no detectable temperature rise of the treated tissue immediately upon treatment or over time, and no macroscopically visible changes in tissue structure. Advantageously, there is no device or structure between where the laser light exits the laser device and the patient's tissue, The light can be emitted from the same light emitter or from multiple emitters. Preferably the light is laser light and is emitted as a line from a hand-held laser device, and the line is waved manually across a treatment area in a continuous, sweeping manner.
