IQ receives US Patent for Right Angle Output Side Firing Fiber April 11 2017

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...

From Abe to MoXy™ and Beyond Part 5: More Fibers of the 1990s February 27 2017

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...

From Abe to MoXy™ and Beyond; Part 3 -- Moses' Math Works January 16 2017

Part 3 is a bit of a departure from my planned sequence for this series. A colleague has graciously permitted me to share a slow motion video that he produced of a generic side fire fiber delivering a single pulse of holmium energy into a beaker of water. Herein I hope to demonstrate that surgical fiber performance can be modeled/predicted, and quite accurately, and that there isn't anything mysterious or magical involved. Sure,...

Side Fire Fiber Technology – From Abe to MoXy™ and Beyond: Part 1 (Basics) December 30 2016

Part 1: Fiber Optics Fundamentals (a prerequisite to understanding side fire fibers) I’ve been told a half dozen tales that purport to describe the origin of fiber optics and likely as many claiming to describe the first side fire fiber, but there is little or no evidence for any stories I have heard over my 30+ years in the field…except the tale of “the Hitachi patent”. Anyone working in side...

Smooth Passage™ Holmium Fiber Tips on ProFlex™ LLF August 29 2016

In the course of studying other manufacturers' holmium laser fibers we sometimes observe surprising differences. In this case, we knew that our tips were different -- heck, we gave them a special name -- but  just how much difference they made was the surprise.      The two fibers in the photo are "1000 micron", meaning they have either a 910 μm or 940 μm core inside a 1 mm diameter glass cladding. The upper...

UV-Purple-Blue Laser Patent Issues October 30 2015

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,...
