摘要:
Physically flexible radiation-emitting probes and associated illumination methods and systems for delivering radiation or light to the interior of a lumen or cavity. Light-emitting devices are immersed in a flowing liquid coolant within a probe to provide high light output power, and convoluted electrical power buss structures provide physical flexibility of a probe about a longitudinal axis. The probes can be configured for delivering light to the interior of any lumen including for performing therapeutic medical procedures at locations in body lumens including the interior of the human gastrointestinal tract.

The present invention provides the ability to treat acne with a device that can be worn by a patient for extended time periods. The device can, for example, enable the delivery of light for time periods that are longer than one might want to sit still in front of a stationary light source. The device is a flexible container that may be fitted to parts of the body to be treated. An example of such a flexible container is a mask for the face (1). The mask covers the face and has a strap (6) to hold it to the face. The mask is worn for a period of time needed to provide the desired amount of light energy to the issue.

摘要:
The present invention relates to the devices and methods for killing and/or debilitating pathogenic microorganisms, such as H. pylori bacteria within a patient's body. A light source (102) is provided that emits electromagnetic radiation having wavelengths within the visible spectrum. The light source can be internal and/or external to the patient's body. For embodiments having an external light source, a light guide (104) is provided for transferring the radiation from the light source to a location within the patient's body. The light guide has a proximal end optically coupled to the light source and a distal end dimensioned for insertion into a patient's body. A delivery element (106) is also provided to optically couple the radiation from the light to a location within a patient's body.

摘要:
Catheters for performing therapeutic and diagnostic procedures within a body, including human or animal body cavities or lumens, and methods for use. One or more distancing member of the catheter can be used to position a sensor or a therapeutic device a minimum distance from a wall of a lumen or cavity. The catheter can include means for actively or passively controlling or modulating its position within the lumen or cavity during a procedure. Methods for using the catheter include nonocclusive deployment in the human gastrointestinal tract for phototherapy procedures, delivering electromagnetic radiation substantially homogeneously or in a desired pattern to the interior of a lumen.
摘要:
The present invention relates to a devices and methods for killing and/or debilitating pathogenic microorganisms in or on a patient’s body, such as light-sensitive bacteria including helicobacter pylori and/or propionibacterium acnes. A chemiluminescent light source provides electromagnetic radiation having predetermined wavelengths in the visible spectrum. The light wavelengths are selected for absorption by naturally-occurring photosensitive chemicals produced by the patient’s body.
