Already FDA-cleared and proven in limited release, both single use devices are now available nationwide.

When paired with Dornier’s Thulio® pulsed Thulium: YAG laser with RealPulse® technology, the Dornier Hoover and Dornier Axis II Slim is designed to be the ultimate trio to provide a fully integrated set-up for dusting, fragment retrieval, irrigation, and suction control in flexible ureteroscopy (fURS), allowing urologists to see, break, and remove kidney stones in one seamless procedure. 

How it works together 

The Dornier Hoover FANS Ureteral Access Sheath provides a stable working environment that enables continuous irrigation, suction, and instrument exchange through this sheath, the Axis II Slim ureteroscope is advanced to the kidney, where it delivers clear visualization of the stone, facilitating precise laser lithotripsy. 

During laser stone disintegration (fragmenting or dusting) the Hoover allows for immediate removal of dust and fragments, maintaining clear visibility, and ensuring efficient evacuation of stone material. 

Together, the three devices streamline the procedure by combining effective stone treatment with rapid, controlled clearance.

Best-in-Class Performance, Proven in In-Vitro Testing

Two pivotal mechanical factors determine the optimal use of Dornier Hoover FANS Ureteral Access Sheaths in flexible ureteroscopy (fURS) procedures; they are suction performance and deflection ability.

Recent peer-reviewed in-vitro studies published in the World Journal of Urology[1][2] found that the Dornier Hoover (Manufacturer: Innovex Medical Co. Ltd.) outperformed other tested devices of the same size in suction performance and delivered superior deflection for improved navigation.

These two parameters are critical for achieving high intraoperative efficiency in stone fragment clearance and for ensuring reliable access to challenging regions of the pelvicalyceal system, particularly the lower pole calyces of the kidneys.

Key competitive advantages of the Dornier Hoover andDornier Axis II Slim include:

• Best-in-class suction performance of the sheath for faster fragment removal compared to competing devices of the same size. 1
• Best-in-class deflection for navigating difficult calyces, even with laser fiber or basket in place.2
• 5.6 Fr. tip scope provides the ideal combination of tight ureteral access and maneuverability for reliable lower pole access.
