From Abe to MoXy™ and Beyond Part 5: More Fibers of the 1990s

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...

From Abe to MoXy™ and Beyond -- Part 4: The 1990s Boom

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...

Introducing the ProView™ 30X SMA Inspection Microscope

InnovaQuartz is pleased to offer a low cost but high performance solution for inspecting SMA (and Trimedyne in January 2017) terminated laser surgical fibers. This battery powered (batteries included) microscope is equipped with a thread-free SMA (or Trimedyne) port that positions the fiber input face within the field of view with acute angle illumination from below. Every detail of the connector face is exposed: scratches, dirt and burns are detected and may be corrected before risking the laser optics. Simply slip the connector ferrule into the aluminum adapter and flip on the light.

What are Holmium Laser Fiber Sizes, Really?

Section 502 of the Federal Food, Drug and Cosmetic Act (FFDCA) says that a device is misbranded if its labeling is false or misleading in any particular. Maybe the FDA doesn’t read Urology? I’m referring to a paper that appeared in the journal Urology a couple of years ago*, questioning the veracity of holmium laser fiber manufacturers in describing the diameters of their fiber devices. The conclusion was that nobody told the truth. That would actually be a good case against holmium fibers being misbranded, in that, if all fibers are uniformly mislabeled, it is not misleading. While the cynic in me appreciates that...

The Power of Collimation IV: Going the Extra Mile

This final Chapter in the blog series, "The Power of Collimation", explores the apparent paradox that ProFlex is able to reject potentially damaging, high angle laser energy within the focus while continuing to deliver more laser energy to the stone than any other holmium laser fiber.
