A lighting arrangement for providing visible light and radiation in another spectrum that is medically beneficial is provided. The lighting arrangement comprises a light source adapted to emit visible light; a radiation source adapted to emit radiation in a predetermined spectrum, and a driver circuit adapted to provide a first driving current that is pulsed and has a duty cycle of not greater than 20%. The predetermined spectrum is preferably in the range 760-1400 nm. The lighting arrangement is adapted to provide the first driving current to the radiation source but not the light source. Corresponding method and products employing such lighting arrangement are also provided.

Apparatus and methods are disclosed for treating allergic rhinitis (seasonal and perennial hay fever), by application of flash lamp radiation. The nasal cavity can be illuminated in a safe and effective manner, with non-coherent light from a flash-lamp or other suitable source. This illumination can be accomplished in any suitable manner, including by use of a handheld device. Such handheld embodiments may contain a power source (battery or AC), control circuitry, light source (flash-lamp or diode laser), lens (focusing or non-focusing), light filter, and/or fiber-optic for delivering light to the nasal cavity. Embodiments include using any suitable light energy, such as visible light in the red wavelengths with a power output of 1 to 10 Joules per cm.sup.2. The device can be pre-programmed to deliver a specified amount of light in a specified amount of time using multiple pulses (in the case of a flash lamp) or a continuous wave (in the case of a diode laser). In many useful embodiments, a rigid fiber-optic extends from the lens/light filter a length of 10 to 20 mm, although it can be any convenient and useful size and shape. Contact sensors can be arrayed on the device for various purposes, such as to restrict illumination to times when the fiber optic is inserted into the nasal cavity. This and/or other safety features can prevent the high-intensity light from being fired into open space, a person's eyes, and/or otherwise causing a potential vision or other hazard. Preferably, the device can be easily and comfortably inserted into a nostril. The fiber-optic can be angled (either in its own shape or by the user manipulating it to a convenient angle/position) so as to allow the user to easily grip the device and insert the fiber-optic without having to use a mirror or other aid. Light from the device can be emitted at a specified light frequency that causes a desired immunosuppressive response in the cellular system.

Phototherapy systems comprising a therapeutic lamp platform for radiant lamps such as LEDs disposed in a holdable spot applicator assembly, the holdable spot applicator assembly including a reflective surface facing towards a patient and a plurality of LEDs for communicating lamp radiation from the lamps to a user. The lamps and associated circuitry are housed within a holdable elongated structure.

A cosmetic method and apparatus for selecting an IPL light source having a band pass filter equivalent to a specified wavelength laser light source for providing cosmetic treatment of skin tissue and being configured to deliver high energy fluences and achieve a threshold energy sufficient to produce a clinical effect during operation.

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.

A system and method of illuminating tissue, particularly within the cranial cavity, through the mouth or nose. The system includes a light source and a power source for powering the light source. Optics are included for directing light from the light source towards the cranial cavity when the apparatus is inserted into a cavity of the head. Light from the light source and output from the optic provides cellular interaction treatment toward a specified area of the head region. Providing illumination where there are already holes in the skull results in more efficient coupling of light to the cells.

A method of operating a flashlamp (2) in a skin treatment system (1) comprises the steps of establishing a conductive path between the flashlamp (2) and a charged capacitor (4) causing a free discharge within the flashlamp, and interrupting said conductive path so as to cut off the current through the lamp when the current density drops below a predetermined current density threshold level (Ix) or when the energy applied to the skin reaches a certain maximum (E.sub.M).

A therapeutic illumination assembly includes a catheter and a point source treatment fiber. The catheter comprises a catheter wall encircling a luminal fluid pathway. The point source treatment fiber is positioned within the luminal fluid pathway of the catheter. Further, the point source treatment fiber comprises a plurality of light emitting point sources intermittently positioned along a treatment length of the point source treatment fiber such that the plurality of light emitting point sources irradiate the catheter when the plurality of light emitting point sources emit light.

A urinary control system for controlling urination has a first light source configured to selectively apply a first light and a second light to a bladder muscle and a second light source configured to selectively apply the first light and the second light to the urethral sphincter. A first optogene is expressed to the bladder muscle and the urethral sphincter, and a second optogene is expressed to the bladder muscle and the urethral sphincter, the first optogene contracts muscles by depolarizing membrane potential when the first light is applied, the second optogene relaxes muscles by depolarizing membrane potential when the second light is applied, and the contraction and relaxation of the bladder muscle and the urethral sphincter are achieved counteractively via photostimulation by the first light and the second light, respectively, so as to control urination.

The invention provides a light therapy device for providing therapeutic treatment to a user's body, wherein the user may be a person or an animal. The device is using a light projection method for treating the body problems and/or skin disorders. Further, the device is having a rotatable assembly that automatically follows the movement of the desired area of the body needs to be treated. The device uses artificial intelligence, machine learning, localization modules, object detection module, image processing module, and 3D-mapping to automatically identify and treating the desired area of the body. Furthermore, the user can manually identify, select and prioritize desired treatment portion and can select the type of treatment required.
