Abstract
Apparatus is provided for the treatment of a medical condition, such as mucositis in patients who are undergoing cancer treatment. The apparatus has several embodiments. In each embodiment, an array of optoelectronic devices, such as light-emitting diodes (LEDs), is used to provide a uniform emission of monochromatic light while producing a minimal amount of heat. The LEDs may be cooled in several ways. The treatments are typically of a very short duration. In several embodiments, selected portions of the patient are treated using a hand-held or stationary lamp. In other embodiments, the entire gastrointestinal tract may be treated simultaneously.
Claims85
A device for treating mucositis in a patient, the device comprising:
- a housing positioned adjacent to the patient;
- a plurality of optoelectronic devices positioned within the housing, the optoelectronic devices emitting radiation at a wavelength suitable for the treatment of mucositis while emitting a minimal amount of heat;
- and
- a cooling system that cools the optoelectronic devices.
A device for treating a medical condition in a patient, the device comprising:
- a gantry suitable for accommodating the patient;
- a housing positioned adjacent the gantry;
- a track coupled to at least one of the gantry and the housing;
- an array of optoelectronic devices coupled to the housing, the optoelectronic devices emitting radiation suitable for treating the medical condition while emitting a minimal amount of heat;
- and
- a cooling system that cools the array of optoelectronic devices;
- wherein at least one of the gantry and the housing moves along the track in order to change a relative position between the gantry and the housing so that the radiation emitted by the array of optoelectronic devices is directed toward the patient.
A device for treating a medical condition in a patient, the device comprising:
- a first housing unit;
- a second housing unit coupled to the first housing unit;
- and
- a first array of optoelectronic devices positioned within the first housing unit and a second array of optoelectronic devices positioned within the second housing unit,
- the optoelectronic devices emitting radiation suitable for treating the medical condition while emitting a minimal amount of heat,
- the first and second housing units positioned adjacent to the patient so that the radiation emitted from the optoelectronic devices substantially encircles the patient.
A device for treating a medical condition in a patient, the device comprising:
- a plurality of modules, each one of the plurality of modules including
- at least one electrically and thermally conductive lead frame substrate having an upper surface and being adapted to act as a heat sink,
- at least one optoelectronic device electrically connected to the upper surface of the lead frame substrate, the optoelectronic device emitting radiation suitable for treating the medical condition while emitting a minimal amount of heat, and
- at least one connector interconnected with the lead frame substrate that is adapted to interconnect each one of the plurality of modules with at least one other of the plurality of modules;
- wherein the lead frame substrates are interconnected to form an array of a plurality of modules, the array being positioned adjacent to the patient so that radiation emitted by the optoelectronic devices is absorbed by the patient.
A device for treating a medical condition in a patient, the device comprising:
- a housing;
- a plurality of optoelectronic devices positioned within the housing, the optoelectronic devices emitting radiation at a wavelength suitable for treating the medical condition;
- and
- a radiation blanket coupled to the housing and positioned adjacent to the patient so that radiation emitted by the plurality of optoelectronic devices is directed toward the patient.
