Foothill Ranch, Calif. – U.S.A. – December 9, 2015 — An updated technical guide published by Bal Seal Engineering, Inc. provides designers of active implantables with a detailed look at how the company’s Bal Conn® electrical contact technology can ensure consistent, reliable connections in devices used to deliver neuromodulation and cardiac therapies.

The 10-page guide, titled “Electrical Contact Solutions for Medical Active Implantables,” describes how the company’s Bal Conn® electrical contact helps OEMs improve device performance while simplifying the process surgeons use to connect leads to implantables, thus shortening procedure times. The Bal Conn offers low contact resistance and is ideal for devices with high connection counts.

The guide includes technical specifications for bi-directional neuro, bi-directional IS-1, uni-directional and bi-directional IS-4/DF-4, and ventricular assist device (VAD) applications. Illustrated with detailed cross-sections, a full-page chart provides an overview of key design benefits for each application type.

Also included is a section highlighting the SYGNUS® implantable contact system, the world’s first integrated seal and electrical contact system for active implantable devices. This innovative system combines reliable Bal Conn™ electrical contact technology with proven implantable-grade silicone isolation seals, resulting in a densely spaced connector “stack” that can accommodate leads with diameters down to 0.7 mm.

A section on emerging technologies highlights the company’s latest developments, including micro-welded contacts that offer reduced axial pitch, and a high density vertical array, which has been designed to dramatically improve device functionality while reducing overall package size. The subassembly uses vertically positioned pins or rods to double or triple the number of connections available to the device lead.
