Features:

• With upgraded titanium alloy shell. 15 degree curved, 20A conforms to the skull;
• CS-20A is indicated for round window, extended round window and cochleostomy surgical approaches;
• Size decreased 20% comparing to CS-10A;
• 24+2 electrodes include 24 active intracochlear electrodes and 2 external electrodes;
• Advanced state of the Art ASIC Chip;
• Implant ID is the serial number of implant;
• Fast impedance measurement.

Advantages:

• Less bone drilling, more suitable for children;
• Advanced technology, better fit, less surgical trauma;
• Slim electrodes array, safer technology;
• Research and develop the SoC chip independently. Enhance the feature of tonal information collection, improve the communication and music appreciation;
• Implant ID can be identified clearly by NuroSound, matching speech processor and implant one-to-one;
• Fast impedance measurement is used to shorten the impedance measurement time and improve mapping efficiency.

Benefits:

• The overall area of the implant is 20% smaller than CS-10A, minimizing surgical risks.
• 24 channels, more natural hearing;
• Different sizes and lengths of electrode arrays provide customization for various types of cochleas;
• Have good reliability and biocompatibility, reduce risk of infection;
• Slim tip, reduce damage to the fine structure of the cochlea and preserve the residual hearing of the recipient;
• Shorten the impedance measurement time, improve mapping efficiency, shorten operation time

Description:

The raw materials of the implants are all from the United States, comply with FDA standards, have good reliability and biocompatibility, and reduce risk of infection. Upgraded on the basis of CS-10A, the upgraded titanium casing and closely arranged coils further improve the impact resistance of CS-20A.

Nurotron's implants can resistant against external impact up to 2.5 joules, and helium leakage standards are 50 times stricter than international standards.

The overall area of the implant is 20% smaller than CS-10A, minimizing surgical risks.

Removable magnet, more suitable for different level of MRI scans, to ensure the best imaging outcome.

CS-20A has three types of electrode arrays, slim short electrode, slim medium electrode and slim long electrode, with lengths of 16.0mm, 20.5mm and 24.0mm respectively. Different sizes and lengths of electrode arrays provide customization for various types of cochleas.

Except for the TS electrode, which has 22 channels, the other electrodes have 24 channels. More channels can help recipients closest to natural hearing.

The apical end diameter of the slim electrode is 0.3mm and basal end diameter is 0.8mm. It is moderately soft and hard and is indicated for round window, extended round window and cochleostomy surgical approaches. This is designed by Professor Stephen J Rebscher, the world's top electrode expert. This design not only minimize the occurrence of vertical deviation into the scala media or scala vestibuli, it can also reduce damage to the fine structure of the cochlea and preserve the residual hearing of the recipient.

The implant is available in monopolar, bipolar or common ground stimulation modes, designed for flexible programming options.

Telemetry functions available with the implant include NRM, ESRT, ABR, CEP and intraoperative NRM.
