Ci24re-CA

ELECTRODE ARRAY

Contacts
• 22 half–banded platinum electrodes, positioned over a 15mm active array in a non–uniform arrangement
General features
• Stylet – holds the electrode straight for insertion with Advance Off–Stylet™ (AOS) surgical technique
• Softip™ electrode – minimize lateral wall insertion force
• Two extracochlear electrodes – one platinum plate attached to the implant receiver/stimulator package
and a separate 1.5mm diameter ball electrode on an 80mm lead
• Handle at the end of the electrode for easier handling during surgery and electrode orientation

RECEIVER/STIMULATOR

General features
• Weight – 9.5g
• Titanium casing for high impact resistance
MRI
• MRI safe at 1.5 Tesla with magnet removed (for further details refer to the latest surgery guide)8
• Sterile replacement implant magnet (Item# Z50101) star should face skin side

MICROELECTRONIC PLATFORM

General features
• Power efficient, custom design
• Stimulus amplitude range: 0μA to 1.75mA
• Stimulation rates up to 31.5kHz
• Pulse width: 9.6μs to 400μs per phase
• Implant ID to uniquely identify implants
Stimulation modes
• Monopolar, bipolar mode and common ground stimulation, biphasic current pulses
Telemetry capability
• Ultra–low–noise floor (~1μV) – enabling advanced AutoNRT™ telemetry capabilities
• Includes fully integrated telemetry modes – NRT, AutoNRT and intraoperative NRT
• Supports electrophysiology – ESRT, ABR and CEP


Ci24re-ST

ELECTRODE ARRAY

Contacts
