Quartet H2O LDD Actively Cooled Lateral Surgical Fiber Optic

Infrared surgical lasers, e.g., CTH:YAG @ 2100 nm and TM:YAG @ 2000 nm, are wonderful tools for minimally invasive surgery such as laser vaporization of hyperplastic prostate tissue (BPH), but they are completely incompatible with right angle, off-axis delivery. Fiber optics find great utility for vaporization of prostate gland lobes about the urethra at less-challenging wavelengths, e.g., 532 nm, where water is transparent. The fundamental advantage of infrared lasers is strong absorption by water (within tissue), but this very absorption renders water-cooled side-firing fibers useless with these laser generators, i.e., MoXy® by Boston Scientific; where the surgical beam passes through the coaxial cooling jacket, the coolant boils and blocks further flow, overheating the device rapidly.
