Ceramic-to-Metal Solutions for Implantable Cardiac Devices
Cardiac Rhythm Management (CRM) devices are among the most established and reliable active implantable medical technologies. Pacemakers, implantable cardioverter-defibrillators (ICDs), and next-generation leadless systems depend on hermetic packaging capable of protecting sensitive electronics for many years inside the human body.
For decades, SCT has partnered with leading medical device manufacturers to develop customized ceramic-to-metal assemblies that combine hermeticity, miniaturization, electrical performance, and long-term reliability for implantable cardiac applications.

06 – FAQ
Frequently Asked Questions
Why are ceramic feedthroughs used in pacemakers and ICDs?
Ceramic feedthroughs provide the electrical insulation needed to transmit power and signals while maintaining a hermetic barrier between the implant’s internal electronics and the body.
Long-term hermeticity is essential for protecting sensitive electronic components from moisture and ensuring reliable device performance over many years of implantation.
SCT develops customized ceramic feedthroughs designed to combine hermeticity, electrical performance, and long-term reliability for implantable cardiac devices.
What is a filtered feedthrough?
A filtered feedthrough integrates electromagnetic filtering directly into the electrical interface of the implant. By reducing unwanted electromagnetic interference (EMI), it helps protect sensitive electronics while maintaining a hermetic seal.
SCT develops customized filtered feedthrough solutions that combine electrical interconnection, EMI protection, and long-term hermeticity within a single component.
Why is hermeticity critical for cardiac implants?
Pacemakers and ICDs are expected to operate reliably inside the human body for many years without maintenance. Maintaining a hermetic seal helps protect sensitive electronics from moisture ingress throughout the life of the implant.
SCT combines decades of ceramic-to-metal brazing expertise with advanced manufacturing technologies to develop hermetic packaging solutions designed for long-term implant reliability.
How does miniaturization influence cardiac implant design?
As implantable cardiac devices become smaller and more sophisticated, manufacturers must integrate more functionality into increasingly compact packages while maintaining electrical performance and long-term reliability.
SCT works closely with customers to co-develop miniaturized ceramic feedthroughs and packaging solutions that support next-generation implant architectures without compromising manufacturability or robustness.
Why choose ceramic instead of polymer or glass for implantable feedthroughs?
Advanced ceramics combine excellent electrical insulation, biocompatibility, mechanical stability, and long-term hermetic performance. These properties make them particularly well suited for implantable devices expected to remain reliable for many years.
SCT develops high-performance ceramic-to-metal assemblies tailored to the demanding electrical, mechanical, and environmental requirements of cardiac implant manufacturers.
What role do ceramic feedthroughs play in leadless pacemakers?
Leadless pacemakers require highly compact packaging solutions capable of maintaining electrical performance and hermeticity within a significantly reduced footprint.
SCT develops miniaturized ceramic feedthrough technologies that help manufacturers meet the demanding packaging challenges associated with next-generation leadless cardiac devices.
