Abstract
A medical system for transmitting and delivering to a tissue site multiwavelength therapeutic radiant energy along a common optical pathway. Also included is a laser catheter suitable for engaging multiple sources of laser energy and transmitting multiwavelength therapeutic laser energy along a common optical path for delivery to a worksite.
Claims10
A method comprising:
- using a first laser to generate a first beam of electromagnetic energy having a first wavelength on the order of 3 microns;
- using a second laser to generate a second beam of electromagnetic energy having a second wavelength on the order of 1 micron;
- coupling energy from said first laser to a metal halide optical fiber;
- coupling energy from said second laser to said metal halide optical fiber;
- guiding said energy having said first wavelength along said metal halide optical fiber at a dosage which cuts tissue;
- guiding said energy having said second wavelength along said metal halide optical fiber at a dosage which coagulates tissue;
- cutting tissue using said energy at said first wavelength;
- and
- coagulating tissue using said energy at said second wavelength.
