An interoperative light therapy apparatus and method are disclosed. The apparatus includes an excitation light source, a plurality of light emitting devices and a plurality of light detecting fibers, wherein the plurality of light emitting devices produce a fluorescence light in cancerous cells of a patient treated with a photosensitizing medication. The fluorescence light is collected by the plurality of detector fibers and a digital spatial image of the cancerous cells is produced. The digital spatial image is useful for targeting the cancerous cells in a subsequent resection procedure. An interoperative light therapy apparatus is disclosed that further include a therapy light source that can deliver therapy light to the cancerous cells using the digital spatial image in the subsequent resection procedure.

The present invention provides for devices and methods of treating wounds, including general wounds, gum disease and gingival tissues post scaling/root planning, using a diode laser which generates a beam of light having a wavelength in the visible portion of the electromagnetic spectrum (400 nm-700 nm). Further disclosed are devices and methods capable of stimulating tissue regeneration at the site of a wound.

A peripheral light-emitting linear light guide member is composed of an optical fiber including a core having an outer periphery surface exposed from a cladding at one end in a longitudinal direction, and a light-scattering member covering an entire periphery of the outer periphery surface at an exposed portion of the core over a predetermined axial length range. The light-scattering member scatters a light emitted from the outer periphery surface of the core. In the light-scattering member, light-scattering particles are dispersion-mixed with an optically transparent base material having a higher refractive index than a refractive index of the core. An amount of the light-scattering particles around an outer periphery of the core is higher at a distal end of the light-scattering member than at an end closer to the cladding.

A device includes an electromagnetic radiation delivery system such as a laser of light emitting diode infrared emitter configured for delivery of electromagnetic radiation within a sealed canal such as an ear canal, a fiber optic cable configured for delivering or capturing the electromagnetic radiation within the sealed canal, and a photo detector coupled to the fiber optic cable forming a portion of a voice communication system. Other embodiments are disclosed.

A light treatment system includes: a probe configured to be inserted into a body cavity, the probe including an optical fiber configured to propagate light, and a light emitter that is provided at a distal end of the optical fiber, the emitter being configured to emit the light; a balloon catheter into which the probe is inserted, the balloon catheter including a distal end portion that is to be inserted into the body cavity and that is to be dilated by being supplied with a liquid including air bubbles; and an air bubble generator configured to generate the air bubbles to be included in the liquid and change a property of the air bubbles.

Provided herein is a multifunctional aesthetic system including a housing, an electromagnetic array situated in the housing and having one or more electromagnetic radiation (EMR) sources, a controller in electronic communication with the array to operate the one or more of the EMR sources to direct the EMR beam to a treatment area, and one or more sensors in electronic communication with the controller for providing feedback to the controller based on defined parameters to allow the controller to adjust at least one operating condition of the multifunctional system in response to the feedback.

An apparatus and methods for tissue restoration are provided. The apparatus may include a catheter shaft extending from a proximal end to a distal tip, the catheter shaft defining lumens including an inflation lumen and a light fiber lumen, a coated balloon positioned on a translucent distal segment of the catheter shaft proximal to the distal tip in fluid communication with the inflation lumen, the coated distal balloon comprising a translucent material and a coated material on an outer surface of the coated balloon, and a light fiber positioned in the catheter shaft in the light fiber lumen and extending through the translucent distal segment.

The present disclosure provides a method for treating ischemic stroke by illuminating a skin surface to reduce free radical generation in subsurface target tissues (e.g., the brain following an ischemic event). The method utilizes a waveguide that receives light from a light source. The waveguide is placed adjacent a skin surface of a patient and the waveguide emits light that passes through the skin surface and illuminates a subsurface target tissue. The waveguide includes light-extracting features configured to emit light at a target angle relative to the surface tissue. That is, the light-extracting features alter a trajectory of light emitted by the waveguide, such that a larger percentage of light emitted by the light guide has an angle that is +/−25 degrees off of a center line of the light guide.
