“All Holmium Laser Fibers are the Same, Right?” Part 5: Beyond Air Well Terminations

FIGURE 1: Trimedyne Holmium Fiber Connector (1991 to Present) Another common termination had its genesis (for holmium laser fibers) at Trimedyne right around 1990 (U. S. Patent No. 5,179,610, Milburn, et al., Figure 1). Trimedyne’s solution is elegant; if a bit over the top for 80W. Knowing that the OmniPulse™ holmium laser presented a laser focal spot that is too large to couple to smaller fibers, and knowing that the laser focus tended to bloom and drift due to localized thermal gradients within the laser rod(s), Trimedyne’s engineers decided to capture and reroute the energy that overfilled the Fiber Aperture....

All Holmium Laser Fibers are the Same, Right? Pt.4 -- Fiber Design Evolution

Part 4: Fiber Design Evolution -- the early days as reflected in today's products First and foremost, for differentiation among holmium laser fibers, is the issue of fiber dimensions. Frankly, I am astonished at the lack of clarity or standardization in identifying fiber sizes within this industry. Almost all “200 micron” fibers are actually much larger than 200 microns; not as egregiously large as described in some of the urological literature, where total fiber diameters are reported as opposed to the fiber core diameters used by manufacturers, but definitely misleading to the point where incredulity dominates. I’ll have more on fiber sizes in...

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

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 one of Boston’s fibers?’ A: Updated answer -- we measured the glass OD of the Boston fibers and, as expected, it is 290 microns (242 microns x 1.2 CCDR). This...

All Holmium Laser Fibers are the Same, Right?   Part 1: An Introduction

Stephen’s Law of Advancing Technology: Without a leader in innovation, product designs converge. Corollary to Stephen’s Law: Dollar-driven designs approach minimum acceptable performance. A tale of two fibers – it’s not the best quality; it’s not the worst quality (upper left -- connector with huge glue ring, steel tube, glass ferrule and the fiber in the very center; upper right -- close-up of fiber input; lower left -- close-up of working tip; lower right -- comet on output of working tip)     While the above is not proof of “Stephen's Law”, it sure supports it. I’m Stephen. The photo series...

Our ProFlex var. Trimedyne Will make you a Fan!

Fiber Holmium Fiber Laser Lasersafe OmniPulse Optifiber Scopesafe Trimedyne

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 capable of reaching lower pole stones because it does not interfere with scope deflection what-so-ever. As a bonus, it delivers more laser power than others' larger core fibers(rated at 25W...
