US Patent number 9,618,700 issued today as a stand alone utility patent covering three embodiments of right angle side fire fibers with 19 claims allowed. The invention is an outgrowth of InnovaQuartz new one-piece side firing fiber caps (Patented) where astigmatic distortion is exploited to permit exceeding the ~75 degree off-axis limit of competing technologies. Ironically, through purposeful distortion the invention produces an essentially distortion-free output as compared with the elliptical distortion suffered by lower angle emission devices. The invention also provided for rotation of the output beyond 90 degrees where there is a need for a back-firing fiber, but not...

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...
