Key Winning Features
- High Channel Count
Thick film technology enables hundreds of electrical feedthroughs — unlike conventional titanium packages with metal pin feedthroughs.
- Electromagnetic Transparency
The ceramic encapsulation is transparent to electromagnetic waves facilitating communication via radio frequency or infrared as well as inductive powering.
- Mechanical Robustness
CorTec´s ceramic packages are designed to survive mechanical impact as for example required for cochlear implants according to EN 45502-2-3:2010 and ISO 14708-7:2013.
- Superior Hermeticity
Protection of electronics against moisture works 10 times longer compared to standard titanium packages — even for small implant volumes below 1 cm3. Lifetime is extendable by additional application of desiccants.
- Freedom of Design
CorTec´s ceramic encapsulations allow application-specific shapes and designs.

- Packages are sealed in 100% helium atmosphere permitting the best possible lifetime prediction based on helium leakage measurements
Customized Telemetric Coils
- Hand-crafted high precision coils
- Materials: Gold or copper
- Up to 50 windings
- Adaptation to the needs of customer-specific inductive power and data interfaces
Medical Grade Silicone Rubber Shell
- Customized void-free silicone molding
- Structural and surface biocompatibility
Connection to Other Products

More technical Information
Materials
In Contact with the Body
- Smooth implant shell and cables made of medical grade silicone rubber.
- All other materials such as the ceramic encapsulation, the feedthroughs, and the metal seal for the package are covered by this silicone shell.
Performance
- Selected designs pass the pendulum hammer test method Eha according to IEC 60068-2-75:1998 – 2.5 J impact.
- Helium fine leak testing for hermeticity:
Extremely low leak rates qualify our packages for rejection thresholds below 10(-10) mbar l s(-1).
