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...

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...

Bill Clinton and George W Bush both promised to 'focus like a laser' on the economy. I'll leave the politics to others and focus like a lens on the lack of scientific rigor for this turn of phrase. At risk of appearing pedantic, I have to point out that lasers aren’t actually focused at all. In fact, collimation (parallelism) is one of the characteristics of laser light that make it unique and useful. Lenses are required to focus laser light. You may ask yourself, “So what? It’s a minor exploitation of poetic license.” I agree, but I needed an entrée suitable for...

Today I was asked a question by a prospective customer that I wish to share with the marketplace at large; that marketplace being laser surgical intervention for kidney and gall bladder stones by endoscopy. Q – I have then an additional question, why do you make 2 SMA version adapted to different brand of laser box. When I look at most of urology company offers, they mentioned that their fibers are compatible with SMA connector but indistinguishably if there are specific for Dornier/AMS or Quanta/Lumenis. What is the difference between the referenced fibers (LT/TG): power limitation? A -...
