Various embodiments are described herein that generally relate to a low-level laser therapy (LLLT) device to aid in at least one of the prevention and treatment of hair loss, rejuvenation of hair, and stimulation of hair regrowth for a certain percentage of users. In at least one embodiment, a plurality of emitters and bristles may be arranged in rows on a concave active surface of a housing for facing a treatment surface of the user. In some embodiments, the device is a laser therapy helmet device, wherein a portion of the device rotates relative to the treatment surface during use. In at least some embodiments, the device may further comprise a plurality of modes of operation for delivering different amounts of energy to the treatment surface.

A medical device assembly is provided for removable insertion into a catheter with a lumen. The medical device assembly comprises an electromagnetic radiation (EMR) source for providing non-ultraviolet, therapeutic EMR having an intensity sufficient to inactivate one or more infectious agents and/or to stimulate healthy cell growth causing a healing effect, and a removable EMR conduction system at least partially insertable into and removable from the lumen of the catheter. The EMR conduction system has at least one optical element providing axial propagation of the therapeutic EMR through an insertable elongate body. The elongate body may have an exterior surface between a coupling end and a distal end tip that has at least one modified portion permitting the radial emission of therapeutic EMR from the elongate body proximate the modified portion. Such modified portion may be gradient along the exterior surface.

Optogenetic signal processing is described for an auditory prosthesis with an intracochlear array of optical stimulation sources implanted in a patient having auditory neurons genetically modified with light sensitive ion channels. Stimulation timing signals are generated for the corresponding auditory neurons for each band pass signal based on characteristic temporal fine structure features of the band pass signals. The stimulation timing signals include: i. one or more channel opening signals adapted to open the ion channels of the corresponding auditory neurons, and ii. one or more channel closing signals adapted to close the ion channels of the corresponding ion channels. Optical stimulation signals are then produced for the optical stimulation sources based on the stimulation timing signals.

Rehabilitation device, comprising a motorized tapis roulant, a harness configured to support the weight of the patient; a plurality of infrared light sources, each one directed to light the muscles of a zone of the lower limbs of the patient; a motorized exoskeleton for lower limbs, configured such that it is fastened to the patient femur, tibia and foot and such that it guides his movements while walking in a combined manner with the movement of said tapis roulant; a user interface, arranged in a position visible for the user; a data processing and control unit, configured to control said motorized exoskeleton and said light sources, characterized in that said processing unit is configured to manage an intensity adjusting cycle of said light sources in a differentiated manner for each one of said sources, as a function of the movement cycle imposed by said exoskeleton to the lower limbs.

Provided is a light-hydrogen therapy including a lighting module, a lighting apparatus and a lighting method. The process of operation is to continuously or discontinuously emit near infrared rays or visible red light to the lower back part of a human head and next to the human neck, while in combination with drinking hydrogen water with dissolved hydrogen of 0.1 ppm to 6 ppm in a container or inhaling a hydrogen gas with 0.1% to 3.8% hydrogen in a container, to improve the body functions of PD patients.

A light therapy device mounting system may include an elongate pole comprising a plurality of holes, a first end and a second end, a mounting device slideably coupled to the elongate pole via at least one hole of the plurality of holes, a top bracket slideably coupled to the first end of the elongate pole, and a bottom bracket slideably coupled to the second end of the elongate pole. The top bracket may include a top hook for receiving a top portion of a door, and the bottom bracket may include a bottom hook for receiving a bottom portion of the door.

A device includes an angiography module, a phototherapy module, a carrier including an optical filter and accommodating the angiography module and the phototherapy module, and a control unit controlling operation of the angiography module and the phototherapy module. The angiography module includes infrared LEDs emitting infrared light through the optical filter to irradiate a limb of a subject, and an infrared sensor sensing a part of the infrared light reflected off the limb to generate a result, based on which the control unit generates an angiogram. The phototherapy module emits infrared light through the optical filter to irradiate the limb for phototherapy.

Provided area an operating method for a laser device for skin, having improved treatment efficacy, or a treatment method for improving skin conditions. In the method according to an aspect, energy generated from a medical laser beam may be selectively transferred to a specific treatment area, which may be implemented in one device. Therefore, the method may contribute to improving the efficacy of laser treatment.

Photobiomodulation therapy systems provide a highly effective way to treat many common ailments to the human body. Many embodiments described herein enable two or more light therapy devices to be communicatively coupled together in various ways. In some embodiments, the light therapy system includes a first light device and a second light device arranged and configured to be communicatively coupled to the first light device. Each of the light devices may include a housing, a communication module, and a plurality of lights arranged and configured to emit at least one of red light and near infrared light.

Brush portions are configured for use with a handheld device. The brush portion includes at least one bristle disposed on a bristle base, the bristle having an elongate first electrode, an elongate second electrode abutting the first electrode, and an insulator disposed between the first electrode and the second electrode. The first electrode and the second electrode are electrically connectable to a first voltage source and a second voltage source of the device, respectively.
