AccuFlex Single-Use Holmium Laser Fiber The AccuFlex Single Use Holmium Laser Fiber is designed to efficiently deliver focused holmium energy and offers the necessary flexibility to meet the challenging deflection needs of flexible ureteroscopy. The AccuFlex Fiber combines a patented Black Hole SMA Connector with a specialized fiber construction that is designed to maximize performance and flexibility while minimizing scope and laser console damage. The AccuFlex Fiber also features a laser-polished distal output tip designed to prevent energy loss as the laser energy leaves the fiber. EFFICIENT ENERGY TRANSMISSION An independent study demonstrated that the AccuFlex 200 Fiber delivered up to 63% more energy than the ACMI/Dornier 200 Brand Fiber at the same power settings.* Energy output of 200 micron fibers with 500mJ input* 450 400 350 408 300 FLEXIBILITY The construction of the AccuFlex Single Use Laser Fiber offers a high degree of flexibility compared to other fibers. In an independent study the AccuFlex 200 Micron Fiber was mJ 250 200 150 100 250 shown to deflect up to 272 degrees in a DUR -8 Elite ureteroscope.* 50 0 ACMI/Dornier 200 AccuFlex 200 VARIETY OF SIZES The AccuFlex Fiber is offered in a wide variety of sizes to meet the needs of different surgical situations. The smaller AccuFlex Fiber sizes are designed for optimum performance during flexible ureteroscopy, offering a high degree of flexibility and visibility. The larger sizes are well suited for semi-rigid ureteroscopy, cystoscopy, and percutaneous applications. The AccuFlex 150 Fiber is the smallest core urology fiber available today.

BLACK HOLE SMA CONNECTOR The AccuFlex Single Use Laser Fibers use the Black Hole Proximal SMA Connector. This SMA connector is designed to diffuse errant laser energy in the event that a laser console’s laser beam is not perfectly aligned as it enters the fiber. This corrective feature is designed to address a cause of fiber “burn out” in competitive laser fibers. Fiber “burn out” is a common cause of scope damage and preventing “burn out” can save costly repairs. The hermetic fiber face is designed to prevent damage to laser optics which can also be costly.

This tip deterioration can result in loss of energy delivery of up to 30%.** The laser-polished tip of the AccuFlex Fiber is designed to offer efficient energy transmission and may reduce fiber deterioration. Because the AccuFlex Fiber is single use, every case starts with a new laser-polished tip for optimum performance.

The core size of the AccuFlex 150 Fiber is 45% smaller than the core of the ACMI/Dornier Super 200 Fiber. Smaller devices create less resistance to steering flexible ureteroscopes and offer better irrigation and visibility than larger devices. The AccuFlex 150 Fiber is the smallest commercially available fiber for use with Holmium lasers.
