Designed for optimal cochlear placement for full-spectrum hearing
Smallest pre-curvedstylet electrode
designed to fit safely
in each individual cochlea
Most Like Normal Hearing
The HiFocus™ Mid-Scala electrode, being part of the HiFocus family, delivers focused stimulation through current steering technology — available only from Advanced Bionics — for hearing that more closely resembles normal hearing. Current steering utilizes 16 independent current sources to increase the number of distinct pitches heard. AB’s patented HiFocus electrode contacts are the ideal platform to deliver AB’s superior sound processing strategies for the best possible hearing outcome.
Strength in Design
Why this Matters to You
HiFocus Mid-Scala Electrode
Designed for Mid-Scala Placement
The patented design offers lowest insertion forces and no contact with the delicate structures of the cochlea
Designed for Optimal Insertion
Ideal insertion depth and placement for maximum performance1-3
Designed as the Smallest Pre-Curved Stylet Electrode
Easy and optimal surgical placement, designed to fit safely in each individual's cochlea
Designed for Focused Stimulation
Patented electrode contacts with Mid-Scala placement provide the perfect platform for current steering
Designed for the Surgeon
Developed for latest soft surgery techniques, including round window insertion, with dedicated tooling for precise control
Designed for the Patient
Studies have shown that patients may retain some of their hearing when cochlea structures are undamaged during electrode insertion4,5
Designed for Reliability
Robust mechanical improvements of the HiRes 90K implant that leads the industry with a 99.8% one-year cumulative survival rate (CSR)6
The HiFocus™ Mid-Scala electrode for HiRes™ Ultra and HiRes 90K™ Advantage cochlear implants from Advanced Bionics is the industry’s latest innovation in electrode design. Developed through extensive research and using state-of-the-art manufacturing processes, the HiFocus Mid-Scala electrode has been designed for optimal placement in the cochlea.
Featuring the industry’s smallest pre-curved stylet array, the HiFocus Mid-Scala is also the industry’s only pre-curved electrode developed for the latest soft surgery approaches, and favored by surgeons for round window insertion in validations8 and clinical studies6.7. Only AB offers surgeons the choice of using a freehand technique or a special insertion tool uniquely designed for easy control and placement. AB also exclusively provides the ability to reload the electrode in the OR.
HiFocus™ Electrode Family: More Options for Better Hearing
HiFocus™ 1j Electrode
AB’s HiFocus 1j electrode is designed for highly effective placement inside the cochlea. With a robust design and ease of implantation, the HiFocus 1j is the electrode of choice for many surgeons worldwide.
HiFocus Helix™ Electrode
AB’s HiFocus Helix electrode is designed to conform to the cochlea’s natural contour. It can be implanted using more than one surgical approach and offers the ability to reload the electrode providing peace of mind to the surgeon.
