Abstract
The present invention relates to devices and methods for killing and/or debilitating pathogenic microorganisms, such as the H. pylori bacteria within a patient's body. A light source 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 a light source external to the body, a light guide is provided for transferring electromagnetic 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 is also provided to optically couple electromagnetic radiation from the light to a location with a patient's body.
