Four dimensional (4D) energy-field package assembly for projecting energy fields according to a 4D coordinate function. The 4D energy-field package assembly includes an energy-source system having energy sources capable of providing energy to energy locations, and energy waveguides for directing energy from the energy locations from one side of the energy waveguide to another side of the energy waveguide along energy propagation paths.

Light administering device and methods of administering a dosage of light using the light administering device. The light administering device includes a light source configured to emit light rays and a collimating lens. The collimating lens is configured to collimate the light rays emitted from the light source such that the light rays are aligned in a light-emitting direction. The light administering device is configured to administering a dosage of light in the light-emitting direction towards the eyes of a user. The light administering device including may include plurality of light sources.

A method of enhancing penetration of a topical composition of 5-aminolevulinic acid (ALA) into tissue for photodynamic therapy includes topically applying ALA to a treatment area to be treated with photodynamic therapy. The method further includes, after the ALA is applied to the treatment area, covering the treatment area with a low density polyethylene barrier. The treatment area is covered with the low density polyethylene barrier prior to light treatment to minimize transepidermal water loss from the treatment area.

An adjustable illuminator for photodynamically diagnosing or treating a surface includes a plurality of first panels and at least one second panel. The plurality of first panels have wider widths and the at least one second panel has a narrower width. The narrower width is less than the wider widths. The illuminator further includes a plurality of light sources, each mounted to one of the plurality of first panels or the at least one second panel and configured to irradiate the surface with substantially uniform intensity visible light. The plurality of first panels and the at least one second panel are rotatably connected. The at least one second panel is connected on each side to one of the plurality of first panels. The second panel acts as a “lighted hinge” to reduce or eliminate optical dead spaces between adjacent panels when the illuminator is bent into a certain configuration.

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.

A surgical site infection management lighting system and method that utilizes Far Ultraviolet C radiation that is safely used to eliminate or reduce surgical site infections. An integrated visible lighting system that includes far ultraviolet radiation doses that are safe for human cell exposure and patient and medical practitioner because of the designed and engineered and computer programmed for pathogen destruction at low doses. The lighting and electromagnetic radiation system provides illumination and for high visibility which provides medical staff optimal vision while performing a surgical or medical procedure. The system further uses electromagnetic radiation frequency of 1.489-1.350 PHz and other frequencies that are pre-engineering and computer programmed for each electromagnetic radiation event during a surgical or medical procedure. The system will efficiently and safely keep all doses substantially low and safe for human exposure while effectively killing and destroying pathogens.

A catheter device for use in the photodynamic treatment of a body cavity or hollow organ of the body, such as the bladder, the device being used in the photodynamic treatment of abnormalities, disorders or diseases of the internal surfaces of said body cavity or hollow organ.

Products, compositions, systems, and methods for modifying a target structure which mediates or is associated with a biological activity, including treatment of conditions, disorders, or diseases mediated by or associated with a target structure, such as a virus, cell, subcellular structure or extracellular structure. The methods may be performed in situ in a non-invasive manner by application of an initiation energy to a subject thus producing an effect on or change to the target structure directly or via a modulation agent. The methods may further be performed by application of an initiation energy to a subject in situ to activate a pharmaceutical agent directly or via an energy modulation agent, optionally in the presence of one or more plasmonics active agents, thus producing an effect on or change to the target structure. Kits containing products or compositions formulated or configured and systems for use in practicing these methods.

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.

According to an aspect, there is provided a treatment device for performing a treatment operation on or to a subject. The treatment device comprises: an optical diffuser arranged on the treatment device such that an outer surface of the optical diffuser is proximate to, or in contact with, skin of the subject when the treatment device is to be used to perform the treatment operation; and an imaging unit for obtaining one or more images using light passing through the optical diffuser into the treatment device; wherein the treatment device is further configured for providing one or more images to a processing unit for determination of whether the treatment device is in contact with the skin.
