Two pgms are playing an important role in a new product which can help to deliver electrical therapy signals through implantable medical devices.

Bal Seal Engineering has developed the SYGNUS Implantable Contact System, which combines contacts and isolation seals in a standard stack configuration.

The company's Platinum-Iridium Canted-Coil springs, which sit in metal housings made of MP35N, form the electrical contacts, while the seals are implantable grade silicone.

"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," noted Design World Online.

"Ideally, developers need integrated, standard, pre-tested header systems, which could accelerate the development process."

SYGNUS is thought to achieve this target by connecting leads to electronics in implantable impulse generation devices used in cardiac rhythm management, neuromodulation and neuro-sensing therapies.

The platinum and iridium spring boasts multi-point conductivity and low insertion force, while also compensating for surface irregularities, according to the news provider.

Platinum curing is viewed as an ideal solution for medical implants which call upon silicone plastics, as the alternatives contain a risk of leaking chemicals into the body.
