Advanced Bionics Mid-Scala Electrode Atraumatic Insertion, Maximised Performance

atraumatic insertion and residual hearing preservation protect the delicate structures of the cochlea and preserve residual hearing. The all-new HiFocus Mid-Scala electrode has been designed to Scala Tympani Profiles, n=35 • Industry’s thinnest pre-curved array • Lowest insertion forces • Avoiding cochlea structures • Small cochleostomy of 0.8mm • Electrode diameter approx. 0.5 mm at 1st contact, 0.7 mm at 16th contact

unique mid-scala placement for maximized performance Featuring the industry’s newest innovation in electrode design, the HiFocus Mid-Scala has been developed for placement in the middle latest soft surgery approaches, including round window insertion, can be utilized to suit surgeon preferences and individual recipient needs. of the scala tympani. The • Electrode located central to perimodiolar • Ideal basal placement for high frequencies1 • An angular insertion depth designed to cover the main spiral ganglion cell population2 • Ideal positioning in scala tympani for maximum performance3 whilst...

consistent insertion depth to ensure full-spectrum hearing optimal cochlear placement and focused stimulation to provide patients with the full spectrum of sound. The patented electrode contacts provide the ideal platform for current steering. The HiFocus Mid-Scala is designed for • Consistent insertion depth • Suits all cochlea sizes • Covers low-frequency-receptive regions of spiral ganglion cells Distribution of Insertion Depths 12 11 10 HiFocus Mid-Scala electrode Mean Depth: 422˚ n=35 Std.
