Abstract: A phototherapy and massage apparatus is disclosed for treating medical conditions in a patient's body cavity. The phototherapy and massage apparatus comprises a light source embedded in a hollow massage wand to produce therapeutic light. The massage wand can be inserted into the patient's body cavity to provide mechanical massage to the tissue inside. A portion of the massage wand is substantially transparent to the therapeutic light such that the therapeutic light can transmit through the massage wand to provide phototherapy to the same subject tissue.

Abstract: An improved phototherapy apparatus for preventing and treating pressure ulcer and other abnormal skin conditions. The phototherapy apparatus comprises a flexible pad which can be built into or placed on top of a bed. A plurality of light emitting diode (LED) or laser light sources and a plurality of pressure sensors are embedded in the flexible pad. Each pressure sensor is associated with one LED or laser light source for monitoring the pressure endured by a specific body area of the patient. When a pressure above certain level is observed, the corresponding LED or laser light source is turned on to provide phototherapy treatment to the pressured area for preventing and treating pressure ulcer and other abnormal skin conditions.

Abstract: Apparatus and method for applying phototherapy treatment after the use of a bio-scaffold or a bio-implant. Bio-scaffolds are used to regenerate tissue and help the body use its own cell in tissue repair. Phototherapy treatment promotes and speeds up this process by enhancing cell proliferation and differentiation, collagen production/synthesis, fibroblast activity, etc.

Abstract: An improved method for performing phototherapy. The method comprises a step of applying a supplement to the patient before/after light treatment, which produces nitric oxide in the subject biological tissue to be treated. The nitric oxide serves as signaling molecules to cause vasodilatation and increase blood flow and micro-circulation in the biological tissue so as to enhance the effect and reduce the required treatment time of phototherapy.

Abstract: A phototherapy apparatus with interactive user interface for treating biological tissue of an animal or human target. The user interface comprises intuitive graphic menus which allow the clinicians or practitioners to define the properties of the biological tissue through easily observable physical characteristics such as weight, skin color, and hair color of the patient. The central control unit of the phototherapy apparatus then automatically optimizes the parameters of the light source according to the properties of the biological tissue and generates an appropriate treatment protocol to produce the optimum phototherapy result.

Abstract: A laser disinfection apparatus with a spectroscopic sensor for performing real-time monitoring of the apparatus's effectiveness. The spectroscopic sensor measures optical spectra of the biological tissue and obtains the concentration of the bacterial/fungal cells by tracking the intensity variation of a fingerprint region of the optical spectra. The acquired bacterial concentration information is used to evaluate the effectiveness of the laser treatment as well as to provide feed-back control of the laser parameters to obtain the optimum disinfection result.

Abstract: A laser protection device that can stay tightly on an animal by going over its head and eyes using a flexible material such as nylon. The device has polymer or glass windows that are designed to block or attenuate the treatment light in order to protect the eyes of the animal from laser damage. As an integral feature, the windows are partially transparent in the visible spectrum to allow the animal to see its surroundings.

Abstract: A photo therapy and massage apparatus for relieving pain in a patient's body cavity. The photo therapy and massage apparatus comprises a light source to produce therapeutic light and a hollow massage wand capable to be inserted into the patient's body cavity to provide mechanical massage to the tissue inside the body cavity. An optical light guide with its proximal end coupled to the light source and its distal end embedded in the hollow massage wand is used to deliver the therapeutic light from the light source to the massage wand. The distal end of the optical light guide is configured to emit the therapeutic light from a side surface. The therapeutic light then transmits through the hollow massage wand to treat the tissue inside the body cavity.

Abstract: A photo therapy apparatus utilizing optical fibers embedded in a cast bandage. The optical fibers are used to deliver therapeutic light to the treatment area after the cast bandage is applied. The therapeutic light helps to decrease inflammation, pain, and irritation as well as to promote healing of the broken bones or sprained/strained muscles of the patient.

Abstract: A phototherapy method for assisting the transvenous lead placement for cardiac resynchronization therapy (CRT) and dilation of occluded veins for any implantable lead placement. The phototherapy treatment helps increase blood flow, reduce inflammation, and enhance angiogenesis to facilitate optimal positioning of the leads.

Abstract: There is provided a phototherapy apparatus, in which the therapeutic light is delivered through one or more massage components. The massage component provides mechanical massage to the subject biological tissue and modifies the properties of the subject tissue in thickness, density, etc. to facilitate the absorption of the therapeutic light and enhance the effect of the phototherapy procedure. The light source of the phototherapy apparatus is actively cooled by a synthetic jet cooler.

Abstract: This invention relates to an optical power monitor based on thermo-chromic material. The incident light produces a temperature change in the thermo-chromic material, causing a change in its color which is utilized to monitor the power level of the incident light.
