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.

 

Ho:YAG Fibers: One 'Size' Does Not Fit All September 19 2016

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...

Compatibility Memo for ProFlex™ LLF Holmium Fibers September 09 2016

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...

The Devitrification Cascade -- Blast Shield Disease & Contagion August 15 2016

Initiation, Progression and Transmission of Holmium Laser Blast Shield Failures My business partner has repeatedly told me not to assume that others know what I know – “Get the information out there, Stephen. Much that you take for granted is new and valuable to others.” It’s hard to know what these nuggets of value are. I am usually enlightened by a customer question, complaint or concern. That is the case for...

All Holmium Laser Fibers are the Same, Right? Part 9 August 02 2016


All Holmium Laser Fibers are the Same, Right? Part 8: Moses and the Stones July 12 2016

Losses due to boiling water in surgery can be much larger than most surgeons appreciate and, in some cases these losses approach the total pulse energy, rendering laser surgery ineffective. It is important to know the variables affecting boiling losses and how to negotiate around these losses to optimize efficacy in laser lithotripsy.
