Developers of active implantable medical devices used in cardiac health management and neuromodulation applications are being pressured to move quickly from design to prototype to build. One area where valuable time and financial resources is often lost is in the development of header systems—devices that deliver electrical therapy signals through a lead. Ideally, developers need integrated, standard, pre-tested header systems, which could accelerate the development process.

A tiny stack of seals and contacts being introduced by Bal Seal Engineering, Inc., a global provider of custom-engineered sealing, connecting and conducting solutions, has the potential to accelerate the introduction of breakthrough devices and therapies. The SYGNUS™ Implantable Contact System combines electrical contacts and isolation seals in a standard, platform-ready “stack” configuration. It connects leads to electronics in medically implantable impulse generation devices used in cardiac rhythm management, neuromodulation, and neuro sensing therapies.

The SYGNUS system pairs the company’s Bal Conn™ electrical contact technology with pre-tested silicone seals. The series of electrical contacts are Platinum-Iridium Canted-coil™ springs in metal housings made of MP35N. The seals are implantable grade silicone.

The number of contacts and seals in the SYGNUS system is configurable to meet unique application and industry requirements, such as the IS4 standard for cardiac health management devices, for the development of devices that stimulate or block spinal nerve signals, and other medical applications. The Canted-coil™ spring contact design offers multi-point conductivity and low insertion force, and will compensate for surface irregularities. The system’s silicone seals provide superior dielectric isolation, and the combined stack is resistant to 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.

You can see it first at the MD&M Minneapolis show, October13th-14th, 2010, booth 344.
