Gyrus ACMI, Inc. a leading worldwide manufacturer and supplier ofdiagnostic and therapeutic minimally invasive surgical devices in theareas of Urology, Gynecology, ENT and General Surgery, announces thedevelopment of the world's first Endoscope Protection System (EPS)designed to prevent accidental laser damage to the distal end offlexible ureteroscopes from holmium lasers. When used with the GyrusACMI DUR(R)-D Digital Flexible Ureteroscope, released in September2006, its ultra-miniature (1 mm) Complementary Metal OxideSemi-Conductor (CMOS) distal sensor technology works in conjunctionwith the EPS software to accurately detect the laser fiber position.The EPS response is based on feedback from the CMOS imaging chip atthe distal end of the DUR(R)-D Ureteroscope that instructs the laserto shutdown when the fiber is withdrawn to a position inside theworking channel of the endoscope where damage could occur. £ The EPS software package provides two modes of operation. The"Alert Only" mode accurately detects the laser fiber position andemits an alert tone and "Check-Fiber" warning message on the monitorscreen. In the "Control Laser" mode, the DUR(R)-HL20 laser isconnected to the control unit and can be actively fired if the laserfiber is in the safe field of view. If the laser fiber is retractedtoo far into the ureteroscope, the software emits the alert tone,flashes a "Check Fiber" warning, and places the laser in its standbymode. Shutdown of the laser occurs in less than 100 milliseconds andthe laser cannot be fired again until the fiber is advanced to a safedistance and the laser is put into its ready mode. In trials(1), evenafter 120 laser fiber retractions into the DUR(R)-D Ureteroscope whileactively firing, there was no evidence of damage and ureteroscopeperformance remained unchanged. £ "Surgeons use ureteroscopes to access, diagnose and treat almostall upper urinary tract conditions. Considering that up to 70% ofureteroscope malfunction can be attributed to laser damage, the GyrusACMI Endoscope Protection System (EPS) is an important technologyadvancement that will dramatically decrease the number of repairs andreduce the cost of doing ureteroscopy", stated Roy Davis, CEO, GyrusGroup, PLC (GYG) LSE. £ (1) Evaluation of the efficacy of a novel optically activateddigital endoscope protection system against laser energy damage, Sung,Singh, Schwartz, Mirabile, Hruby, Ryan, Landman, Department ofUrology, Columbia University Medical Center New York, NY, USA, June2007.
