Methods and devices for treating nasal airways are provided. Such devices and methods may improve airflow through an internal and/or external nasal valve, and comprise the use of mechanical re-shaping, energy application and other treatments to modify the shape, structure, and/or air flow characteristics of an internal nasal valve, an external nasal valve or other nasal airways.

System for treatment by photodynamic therapy comprising: —an illuminating device (10) including a light emitting surface for illuminating an internal surface to be treated with a light adapted to activate a photosensitizer compound, the light emitting surface emitting light with a distribution of light power comprising fractions of light power decreasing from a maximum at the light emitting surface, the light emitting surface having a determined illumination profile that provides respective illuminated areas for a plurality of the fractions of light power, —a positioning system (40) adapted to position in real-time the light emitting surface within a reference frame, —an electronic unit (45) connected to the positioning system (40) and adapted to monitor in real-time a dose of light energy delivered to the internal surface based on the illumination profile and the position of the light emitting surface.

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.

The present invention provides a nasal disease treatment aid device, comprising: a nose cover which forms a dome so as to cover the nose of a user and covers the nose while being positioned on the nose of the user; a fixing member which is connected to the left and right sides of the nose cover and fixed to the head of the user so that the nose cover is fixed to the nose of the user; insertion members having, interposed therebetween, a support body provided in the inner space of the nose cover and extending outward from the left and right sides of the support body and are formed in tubular shapes each having a hollow inside that communicates back and forth so as to allow the user to breathe through the nostrils; LED light sources which are provided on one side of each of the insertion members and irradiate therapeutic light into the inside of the nose; and low-frequency stimulation units which are provided on each of the left and right sides of the nose cover and physically stimulate paranasal sinuses while in contact with the paranasal sinuses that are around the nose. Therefore, it is possible to provide necessary help for the treatment of rhinitis and paranasal sinusitis at the same time, and infrared treatment light of a corresponding wavelength using the LED light sources and heat treatment by radiation heat from the infrared light are carried out in parallel such that the resulting light and heat is propagated deep into a nasal cavity so as to be able to effectively improve blood circulation, thereby requiring a shorter treatment time and minimizing side effects such as skin rashes and so on caused by prolonged exposure to light and heat.

Modules, systems and methods for clearing substances from a living body are disclosed. A module may include an instructions receiver configured to receive wireless transmissions of instructions from a master controller located outside of the body when the module is inside the body; an energy receiver configured to receive wireless transmission of non-destructive energy from the master controller located outside of the body when the module is inside the body; an energy converter configured to convert the non-destructive energy received to destructive energy; and an energy emitter configured to emit the destructive energy.

According to some aspects, a medical imaging system is provided. The medical imaging system includes an illumination device and a medical imaging device. The illumination device includes a first light source configured to emit first light having a wavelength range. The illumination device further includes a second light source configured to emit second light having at least one predetermined wavelength band. The at least one predetermined wavelength band is within the wavelength range. The illumination device further includes a dichroic mirror configured to attenuate a portion of the wavelength range corresponding to the at least one predetermined wavelength band and to multiplex the second light with the first light such that the portion of the wavelength range of the first light is attenuated. The light multiplexed by the dichroic mirror is emitted from the illumination device along an optical axis and irradiates an observation site. The medical imaging device includes at least one sensor configured to receive light from the observation site.

A diffuser tip assembly is disclosed for generation of uniform cylindrical illumination from a fiber delivered source. Light propagating into the diffuser tip is initially mixed by a spatial overlap of reflections within a waveguide, reducing the sensitivity of illumination uniformity to the modal structure of fiber delivered light. The waveguide output propagates at least two passes through a reflective cavity having transmissive, light-diffusive walls, enabling highly uniform output. The diffuser tip can be configured to use low-absorbing materials for high power applications. In addition, the method of using visible light as an indicator for diffuser output is described. The combination of uniformity, low heat generation, and a visual indicator are intended to promote safety in a phototherapy procedure.

A stereo colposcope having variable linearity filter systems for both the excitation step and the suppression step, and can be used universally with any fluorescent compound or drug, as is the case of photodynamic diagnosis (PDD). The colposcope is a two-way colposcope because the treatment can be administered by an optical system or by a light-producing radio-frequency electrical current with a diathermic effect which facilitates photodynamic treatment. The colposcope produces ozone, which has an antiseptic effect when applied to the genital tract. A monitor provides for three-dimensional viewing through the use of two video cameras with the DLP (Digital Light Processing) and HDTV (High Definition Television) systems with the use of active lenses.

A multi-phase oral composition and delivery carrier for whitening teeth.

A method of generating a treatment plan for delivering treatment light for intracavitary photodynamic therapy to a targeted region within a cavity of a patient may include receiving shape information for an interior surface of the cavity. A first set of control points located on a first trajectory within the cavity is initialized by assigning, to each of the first set of control points, one or more axis positions of a treatment light emitter relative to the interior surface of the cavity. A simulated total treatment dose is iteratively optimized relative to a set of one or more optimization goals when the treatment light emitter is activated to emit treatment light at each of the first set of control points. The treatment plan is then generated to provide a total treatment dose to the targeted region.
