Consistency of Placement
Key to the design are the precurved shape, allowing the HiFocus Mid-Scala electrode to be inserted consistently with minimal cochlea trauma,20 a straight tip region to avoid tip fold overs, and if desired, the electrode can be loaded on a dedicated insertion tool to support a controlled insertion.
The HiFocus Mid-Scala electrode can be introduced into the cochlea by a surgeon’s preferred approach — freehand or by use of the insertion tool. It can be inserted using the round window, extended round window, or small cochleostomy approach, requiring only a 0.8mm opening. The tip feature is intended to ease the insertion through the round window
The distal blue marker can be used to ensure the electrode is properly positioned prior to the off stylet technique, thus avoiding tip fold over issues. The proximal blue marker provides a visual indication of a ‘full’ insertion depth — representing approximately 420° angular insertion in a standard cochlea, covering the main spiral ganglion population23 for optimal spectral coverage.
