Introducing the ProView™ 30X SMA Inspection Microscope December 15 2016

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...

How to Cleave Surgical Fibers November 22 2016

How to Cleave Laser Surgical Fibers Purpose:        Provide simple instructions for reprocessing flat tip bare fibers for laser surgery. Summary:    Clean cut and flat optical faces are necessary for surgical efficacy in laser surgery. Badly cut fibers deliver energy to target tissue less efficiently and degrade more quickly than properly cut fibers. Step-by-step instructions…. Rationale:      A.A. Griffith developed the first theoretical model for fractures during WWI, inaugurating the Science of...

What are Holmium Laser Fiber Sizes, Really? November 21 2016

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...

The Power of Collimation IV: Going the Extra Mile November 08 2016

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. 

 

The Power of Collimation III: Moses’ Enthalpy November 07 2016

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...

The Power of Collimation II: Bullets, Balls & Skipping Stones November 07 2016

110% power transmission from a 273 micrometer core holmium laser fiber is not fantasy. We see it every day. Learn how.

 

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...

IQ honored as Best Precision Fused Silica Component Manufacturer (2016) August 19 2016

  InnovaQuartz pioneered the use of carbon dioxide lasers for manipulating and machining fused quartz and fused silica glasses under computer control and microscopic imaging way back in 1991 when our founder, Stephen Griffin, gambled that his ideas would actually work and built the first laser system in his 80 square foot laundry room. Our first sale was 6 months after the first dollar was spent and we sold more...

“All Holmium Laser Fibers are the Same, Right?” Part 6: Minding the Gap May 24 2016

  FIGURE 1: Fiber Sleeved with Quartz Ferrule The gap (FIG. 1) between the fiber and the quartz ferrule is a fundamental problem of quartz sleeved fibers because that gap harbors volatile and non-volatile contaminants from production or cleaning. These contaminants are inevitably vaporized and deposit on the blast shield or focusing optic or both. In extreme cases, thermal expansion of materials within the gap can fracture the fiber or...

All Holmium Laser Fibers are the Same, Right? Part 3: Pulsar HPC Introduction April 11 2016

Before updating this entry, a reader asked a question about a statement I'd made about the flexibility of the Boston Scientific holmium fibers AccuMax™ and Flexiva™ that I answered in the updated Part 2 entry. I am leaving my answer to that question in this entry, for congruity. Pardon the redundancy. Q: ‘How do you know Boston’s AccuMax™ and Flexiva™ are stiffer than ProFlex 200 if, as you say, you’ve never seen...

Our ProFlex var. Trimedyne Will make you a Fan! December 04 2015

It has come to our attention that holmium fibers for Trimedyne lasers are in short supply. We are happy to step in and serve this unmet need. You should have switched long ago to save blast shields... Our ProFlex LLF var. Trimedyne  offers five sizes (true 200, 273, 365, 550 and 910) featuring IQ's Pulsar HPC connector and Smooth Passage tips. Our true 200 is the only Trimedyne compatible fiber...
