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...

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.

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...

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.

At InnovaQuartz, we developed a method of making very precise, tiny lenses directly upon the face of an optical fiber. In this third Chapter of The Power of Collimation, I’ll describe just how important this subtle feature really is to the performance of holmium laser URS. In the first Chapter of this blog series, I discussed why holmium lasers launch light into fibers at a substantial fraction of their maximum propagation angle (near maximum NA). We’ll be using computer-generated ray traces to depict what happens with a typical laser focus condition (aka laser launch condition) when coupling to a series of...
