The first integrated seal and electrical contact system for active implantable devices will be introduced at MD&M Minneapolis, October 13. SYGNUS Implantable Contact System by Bal Seal Engineering, Inc, Foothill Ranch, CA, combines electrical contacts and isolation seals in a standardized, platform-ready “stack” configuration to provide a turnkey connecting solution for implantable devices used in cardiac rhythm management, neuromodulation, and neuro sensing therapies.

The system pairs the company’s Bal Conn electrical contact technology with pre-tested silicone seals, resulting in an “all-inclusive package” engineered to help large and small device OEMs improve speed to market and eliminate the need for procurement and testing of individual components.

The number of contacts and seals in the SYGNUS system will be configurable to meet unique application and industry requirements, such as the IS4 standard for cardiac health management devices. The Canted-coil spring contact design will have multi-point conductivity and low insertion force, and will compensate for any surface irregularity.  The system’s silicone seals will provide dielectric isolation, and the combined stack will offer resist long-term material adhesion and potential fatigue caused by multiple-lead insertion cycles. Contacts in the stack will be force and resistance tested, and sealing components will be packaged to critical clean standards.
