A device for insertion into soft tissue including a micro electrode, a micro light source; a stiffening element having a material dissolvable or degradable in aqueous body fluid or a material swellable in such fluid to form a transparent gel; a coat of a flexible non-conducting polymer material on the stiffening element; a base disposed at the rear end of the device. The flexible coat has a distal opening allowing light emitted from the light source to leave the device upon said collapse or dissolution or swelling. Also disclosed is a therapeutic or diagnostic device formed in the tissue from the insertable device, uses thereof, and a method of disposing the insertable device in soft tissue.

Treatment method

A treatment method is disclosed capable of reducing the burden on a patient and enhancing the effect of killing tumor cells. The method includes administering an antibody-photosensitive substance into a vein; inserting an endoscope from a mouth, a nose, or an anus and bringing the endoscope to a vicinity of a tumor after the administering of the antibody-photosensitive substance into the vein; placing an optical fiber into the tumor or in the vicinity of the tumor; irradiating at least one of the tumor, the vicinity of the tumor, or a regional lymph node with a first near-infrared ray by the optical fiber; and irradiating the antibody-photosensitive substance bound to a tumor cell membrane in the tumor cell with a second near-infrared ray after the irradiating with the first near-infrared ray, the second near-infrared ray having a shorter wavelength than that of the first near-infrared ray.

Device for projecting images on the retina

A device to stimulate the retina comprises one or more light sources coupled to one or more optical elements. The one or more optical elements is configured to illuminate the retina with one or more images at a location away from a fovea of a wearer. In some embodiments, each of the one or more images comprises a depth of focus and a spatial resolution. The one or more images can be formed at a distance anterior to the retina, at a distance posterior to the retina or on the retina. In some embodiments, the depth of focus is less than the distance, and the spatial resolution greater than a spatial resolution of the retina at the location.

20220355127 · 2022-11-10 · ·

A hand-held light treatment device configured with interchangeable emitter heads that are pre-programmed with desired treatment protocols and updated from a remote store of treatment protocols. The removable emitter heads each contain one or more treatment LEDs, a tracking light, a task light, a proximity sensor, and a control module. A tip is attached to the emitter head, either removably or integral therewith. In in one embodiment, the tip is integral with the emitter head and emits light perpendicular to the handle. Some embodiments have tips of various shapes that attach to the emitter heads, which permits a single device to direct the emitted energy at nearly any direction. The tips can be disposable or reusable. The light-emitting device may be used in conjunction with distilled water to treat infections, sterilize wounds or to minimize infection prior to surgical closure.
