John Brekke’s fiber design from 1994 is one of the few lateral fiber designs of the era that remains on the market today, marketed as Scatterfree™ by Laser Peripherals. As can be seen in figures 10 and 11 (below the next paragraph) taken from the first patent, the concept is simple and it does basically work. In contrast to Pon, however, Brekke failed to properly identify the true sources of the unwanted emissions from unfused fibers. Quoting the patent, in reference to figures 5 and 6 immediately below, “The reflected light 27 and light 29 are unwanted and potentially unsafe...

The 1990s saw a boom in laser TURP (Transurethral Resection of the Prostate) using mostly Nd:YAG lasers. Nd:YAGs showed promise for lowering the classical side effects of standard TURP, where a hot wire loop is used to melt/carve away strips of hyperplastic tissue; their CW (continuous wave) output produced smoother surfaces than holmium lasers do, they did not strongly interact with the sterile irrigation fluid and were less damaging to fibers than holmium lasers. Laserscope’s ADD-Stat™ fiber -- the progenitor to the Model 2090 used in the GreenLight™ revolution of 2000 -- was a fairly popular device that was used...

Resurrecting Urine Flow with IQ's Phoenix™ BPH Laser The US Patent Office has informed InnovaQuartz that our multi-wavelength surgical laser, that we have dubbed the Phoenix, has issued (US Pat. No. 9,220,563), precisely one year after it was filed. This laser addresses the deficiencies of other photoselective lasers – photobleaching, charring -- for minimal collateral tissue damage at wavelengths between 380 nm and 450 nm. Phoenix targets multiple tissue chromophores, tissue breakdown products and melanoidins, short-circuiting char formation. 20th CENTURY LASER SURGERY Surgical procedures for removing excess tissue blocking the male urethra (BPH) have advanced a great deal in...
