A METHOD AND A LASER DEVICE FOR TREATMENT OF ENDO-CAVITAL INFECTIONS

摘要

A method and an apparatus for the treatment of endo-cavital infections, particularly destructive bacterial infections and post major invasive surgery abscesses. A catheter system is used, which allows the simultaneous drainage of an endo-cavital space and irradiation of an infected locus with laser-generated pulsed ultraviolet light. The laser light wavelength is chosen so as to require radiation, which is lethal to the microorganisms causing the infection, at the lowest possible dose. Alternatively, a diode-pumped solid state Raman laser device is used which can be configured to provide in sequence a selected number of output wavelengths in the ultraviolet spectral range.
