A negative-pressure cup structure includes a negative-pressure cup body and a light therapy module. The negative-pressure cup body has a rim. The light therapy module is received in the negative-pressure cup body and includes a circuit board and multiple light-emitting diodes (LEDs) mounted on the circuit board and irradiating corresponding to the rim. Therefore, the negative-pressure cup structure further has functions of light therapy and skin care.

The present invention is directed to a tandem-structured bio-organic light emitting diode (bio-OLED) for photodynamic therapy, and to a photodynamic therapy device including the same to convert a red light emitted from the bio-organic light emitting diode into a near-infrared light (NIR) emission, thereby enabling the use of a PBM therapy in a wide wavelength range of 600 to 1,000 nm.

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.

A phototherapy treatment apparatus and methods are provided. In particular, the present disclosure provides a phototherapy treatment apparatus configured to diffusely transmit light emitted from a light source to a patient.

A medical imaging system is described that comprises an heating element configured to apply at least one heating pattern element to a material to locally heat the material; a sensor configured to capture the position of the heated material a predetermined time after the application of the heating pattern element; and circuitry configured to determine the change of the heating pattern applied to the material based upon the captured position of the heated material after the predetermined time.

An implantable medical instrument for use within a body includes a container that has an opening and holds a medicinal solution, and a soft portion that closes the opening. The medical instrument further includes a power receiver that receives power transmitted externally, and a light emitter that emits light by way of the power received by the power receiver. The light emitter includes at least one of a first light emitter that emits light having a center wavelength of 600 nm or more and 1100 nm or less, and a second light emitter that emits light having a center wavelength of 400 nm or more and 480 nm or less.

A photothermal treatment device includes: irradiation means that irradiates a lesion tissue in a body cavity with heating light; a thermo-endoscope including endoscopic imaging means that images the inside of the body cavity and thermographic imaging means that images a surface temperature of a tissue in the body cavity as a thermal image; and control means (control personal computer (PC)) that controls an output and an irradiation time of the irradiation means based on temperature information of the thermal image obtained from the thermographic imaging means.

An implantable light delivery device comprises: a core portion cladded in a cladding, the core portion comprising upconversion nano-particles (UCNPs) encapsulated in an encapsulation material. The implantable light delivery device may be used in treatments such as photodynamic therapy to provide an emission of light at a wavelength configured by the selection of UCNPs. The encapsulation material may comprise hydrogel and the cladding may comprise fluorinated ethylene propylene.

A method and a system for light-activated drug delivery. An optical probe is coupled to a tissue for transmitting light signals to the tissue for actuating and/or monitoring drug delivery with a multi-phase method for drug delivery. A first light signal is transmitted through the optical probe for actuating and/or monitoring the drug delivery and a second light signal having a different wavelength is transmitted, simultaneously with the first light signal, through the optical probe for actuating and/or monitoring the drug delivery.

Devices and related methods for impinging light on tissue to induce one or more biological effects, and more particularly illumination devices and related methods for phototherapeutic light treatments in the presence of vitamins are disclosed. Biological effects may include at least one of inactivating and inhibiting growth of one or more combinations of microorganisms and pathogens, including but not limited to viruses. Phototherapeutic light treatments in the presence of vitamins may involve providing one or more vitamins in the form of a coating or film on a surface of a target tissue and irradiating the target tissue with light. By performing the phototherapeutic light treatment in the presence of vitamins, efficacy of the light treatment may be improved, thereby reducing viral loads and/or reducing doses of light received by the target tissue.
