Development of a multichannel implantable connector

Further development of active implantable medical devices (AIMDs) coming along with higher channel counts and improved maintainability raises the requirements for implantable connectors in such systems. We developed a concept for an implantable multichannel connector. Contact pads manufactured by laser-structuring that are embedded into a silicone substrate serve as contact partners. Processing features specific to two laser technologies were exploited not only to cut the materials but also to 3D-shape the surfaces of the contact pads. First tests for the long-term behavior show stable contact and isolation properties during 6 weeks of soaking at elevated temperature.
