An illumination system for a medical technology therapy and/or diagnosis system is provided. The system includes a light source, an optical waveguide, and an optical element in the form of a diffuser element. The optical waveguide has a first end that is connectable or assignable to the light source and the diffuser element is arranged at a second end of the optical waveguide so that light from the optical waveguide is injected into the optical element. The optical element has a lateral surface covered by a reflector layer at least in a section thereof. The reflector layer includes a mirror layer. The optical element has a light-reflecting area covered by the reflector layer and a light-transmissive area that is free of the reflector layer. Thus, light injected into the optical element is reflected on the light-reflecting area and emitted from the light-transmissive area.

An optical stimulation system includes a light source configured to produce light for optical stimulation; a light monitor; an optical lead coupled, or coupleable, to the light source and the light monitor; and a control module coupled, or coupleable, to the light source and the light monitor. The control module includes a memory, and a processor coupled to the memory and configured for receiving a request for verification or measurement of a light output value; in response to the request, receiving, from the light monitor, a measurement of light generated by the light source; and, based on the measurement, reporting a response to the request.

A system is provided for treating a skin surface of a user, comprising: at least one light emitting source configured to focus light on a specified skin region of the user, the light being configured to treat a skin condition of the user; and a controller configured to control emission of the light onto the specified skin region of the user.

There is provided a phototherapy apparatus, in which the therapeutic light is delivered through one or more massage components. The massage component provides mechanical massage to the subject biological tissue and modifies the properties of the subject tissue in thickness, density, etc. to facilitate the absorption of the therapeutic light and enhance the effect of the phototherapy procedure. The light source of the phototherapy apparatus is actively cooled by a synthetic jet cooler.

A stimulation system includes an energy source, an electronics unit with a controller, and an actuator that is coupled with the electronics unit and/or the energy source. The actuator emits electromagnetic waves for stimulation of genetically manipulated tissue. The electronics unit is disposed in a housing. The stimulation system is configured for at least temporary implantation in a human or animal body. The controller controls the stimulation of tissue in the body by way of the electromagnetic waves emitted by the actuator. A selector of the stimulation system selects the area of the said tissue for stimulation. The selector includes a masking device for masking certain areas of the tissue, so that an intensity of the stimulation for the masked areas is reduced or equal to zero.

Provided is a puncture device includes: a needle tube; and a tube that is accommodated within the needle tube, is capable of accommodating an optical fiber, and is composed of a cylindrical optically-transparent material. The needle tube includes a tip member fixed to a distal end of the tube and having a blade surface at a tip thereof, and a base member that is disposed at a position where the base member covers a proximal end of the tube relative to the tip member and that is movable along a longitudinal axis of the needle tube. The base member advances to cause a distal end of the base member to abut on a proximal end of the tip member. The base member retracts to cause the distal end of the base member to move away from the proximal end of the tip member in a direction of the longitudinal axis.

A multi-site probe for interfacing with the central nervous system includes one more structures disposed perpendicularly on a backing layer, where each structure includes a braided sleeve over a flexible or rigid core, and a delivery-vehicle. The structures may include optrodes and electrodes. The location of the probe may be determined through the application of combinatorics.

The invention relates to a positioning apparatus (100) for positioning a light-guiding fiber (206) in a calibration port (208) of a medical apparatus (202) comprising at least one light source (204) for the light-guiding fiber (206), wherein the positioning apparatus (100) comprises an elongate body (102) with two end faces (110, 112) and at least one side face (116). A channel (104) for receiving the light-guiding fiber (206) is formed in the body (102), said channel extending along a longitudinal axis of the body (102) proceeding from a first end face (110). Here, according to the invention, provision is made for the body (102), at least in one portion, to consist of an opaque material in the region of the channel (104) and/or to be coated with an opaque material and for said body to have at least one cutout (113, 118), which extends from a side face (116) and/or the second end face (112) of the body (102) to the channel (104) such that radiation emitted by the light-guiding fiber (206) can only emerge from the positioning apparatus (100) in unimpeded fashion through the at least one cutout (113, 118).

Periodontal disorders such as disorders associated with a dental implant are treated. An average power for a laser is selected via a user interface on a tablet, along with a set of permissible laser parameters provided in response to the selected average power. A gingival trough or flap is created around the implant with the laser. Infected tissue is selectively ablated or denatured via photothermolysis, and a pocket is lased around the affected implant. Marginal tissues are compressed against the implant.

Methods of treating skin disorders are disclosed. The methods involve impinging light having a first peak wavelength on the tissue at a first radiant flux, wherein the first peak wavelength and the first radiant flux is selected to provide an anti-inflammatory effect, and impinging light having a second peak wavelength on the tissue at a second radiant flux, wherein the second peak wavelength and the second radiant flux are selected to either stimulate enzymatic generation of nitric oxide to increase endogenous stores of nitric oxide or release nitric oxide from the endogenous stores are disclosed. Representative skin disorders include pruritus, psoriasis, acne, rosacea, and eczema, and the skin can include the scalp. The methods can reduce stinging and/or itching associated with the skin disorder. The anti-inflammatory wavelengths can be in the range of between about 650 and about 680 nm.
