Abstract:
An apparatus including a light source provides for intracranial treatment of a tissue region of a brain of a patient. The intracranial treatment apparatus comprises an outer shaft having a proximal end and a distal end for positioning within the tissue region of the brain. The outer shaft defines a lumen extending between the proximal end and the distal end of the outer shaft and having at least one aperture adjacent the distal end of the outer shaft. An inner light-delivery element having a distal end and a proximal end is adapted to be operatively connected to the light source. The light-delivery element is configured to be received within the lumen and extend from the proximal end of the shaft to adjacent the distal end of the shaft. The light-delivery element is adapted to deliver light from the light source through the at least one aperture of the outer shaft to the tissue region of the brain in proximity to the distal end of the outer shaft.
Abstract:
There is provided a body illumination device (100) adapted to surround at least a part of a user (102) comprising at least one inflatable structural element and a light emitter (120). The at least one inflatable structural element includes a first inflatable structural element (110). The first inflatable structural element (110) comprises a first inflatable chamber (112) comprising a first wall (114). The light emitter (120) is on or integrally formed with said first wall (114) and is for providing light to the user (102). The body illumination device (100) may be stored easily in a deflated state. Further, the body illumination device (100) does not require relatively expensive structural components, such that it may be provided in a cost-effective manner. Additionally, the device (100) may be easy to use. The device (100) may be used in a method of treatment comprising providing treatment light to the user (102). The treatment may be of psoriasis, eczema or skin cancer, in particular.
Abstract:
Apparatus and methods to enhance light intensity within useful red to near-infrared spectral ranges, using direct or indirect sunlight, or from other ambient white light, are described. The disclosed devices provide high quantum yield photoluminescent ambient light spectrum conversion to increase the supplied energy primarily in the 590 nm-850 nm spectral range. These devices also pass much of the incident light in the spectral range in which the device's photoluminescent materials emit light, thereby greatly increasing the effective intensity of light available in the targeted 590-850 nm wavelength range. The ambient light conversion devices of the disclosure may be incorporated in apparel, bandage-like patches, converting reflectors, large area converters, awnings, window covers, and other articles, materials, and products. The converted light may be used in therapeutic treatments, horticultural and biotechnological applications, and other applications in which the converted light outputs of the present disclosure are beneficial.
Abstract:
Switching power supplies made in accordance with the disclosed technology drive flash lamps of dermatologic treatment devices to emit a sequence of relatively small light pulses that are aligned with particular locations within the waveform of the AC line source. Such power supplies not only enable sufficient light energy in aggregate to therapeutically heat target chromophores in a skin region without causing undesired damage to surrounding tissue, but also provide the added benefit that the corresponding electrical energy need not be substantially drawn from any charged capacitor. The disclosed power supply further compensates for performance degradation of the flash lamps during their usable life, by modifying its operation based on predetermined values that are indicative of flash lamp aging/efficiency characteristics.; The flash lamps and their associated stored values are preferably incorporated into a replaceable cartridge that facilitates user maintenance of the dermatologic treatment device.
Abstract:
Apparatus and method for optical- or optical-and-electrical stimulation of e.g., auditory nerve pathways, for example spiral ganglion in the cochlea or neurons in the cochlear nerve. Several configurations for guiding and directing the optical stimulation are disclosed. Several configurations for guiding and directing the electrical field (used in some embodiments, for sensitization) in and though the destination tissue to which the optical stimulation is directed. In some embodiments, and array of IR VCSELs emit stimulation light, in particular to tissue in the cochlea for restoring hearing. In some embodiments, an electrical signal is also applied in a manner that reduces the amount of light in a pulse that is otherwise needed to elicit a NAP. In some embodiments, a heat dissipater is used to spread the heat generated by operation of the lasers and their circuits, to avoid heat damage to the tissue.
Abstract:
The invention relates to medical engineering, in particular to therapeutic light-emitting devices for treating skin diseases, generating vitamin D and for preventing osteoporosis. The inventive device can be also used in beauty and bronzing shops for cosmetic purposes. The aim of said invention is to increase the performance characteristics of the device by reducing the number of lamps to n and by substituting a smooth circular reflector by a reflector consisting of two types of the alternating sections of evolvent cylindrical surfaces which are combined in the form of a single surface and whose evolutes are embodied in the form of closed curves which confine the convex cross sections of an expected absorber and a lamp, said reflector being disposed between the lamps and a body. Said invention makes it possible to reduce by 3-4 times a consumable electric power and to maintain the previous value of UV-radiation flux.
Abstract:
A system and method for performing fractional resurfacing of a target area of skin using electromagnetic radiation are provided. An electromagnetic radiation is generated by an electromagnetic radiation source. The electromagnetic radiation is caused to be applied to a particular portion of a target area of skin. The electromagnetic radiation can be impeded from affecting another portion of the target area of the skin by a mask. Alternatively, the electromagnetic radiation may be applied to portions of the target area of the skin, other than the particular portion.
Abstract:
Embodiments include an apparatus, a medical device, a method and a system. The medical device includes an ellipsoidally shaped reflector having a first focus and a second focus. The ellipsoidally shaped reflector also provides a translational coupling of electromagnetic energy from the first focus to the second focus. The medical device also includes a controllable electromagnetic energy source aligned to emit a non-biologically emitted electromagnetic energy in a proximity to the first focus.
