Greatbatch Medical has been providing a number of different IS-1 adapters to
the industry in order to connect old 5mm/6mm unipolar leads, 5mm bifurcated bipolar leads,
and 3.2mm bipolar leads to newer pulse generators conforming to the international pacemaker
connector standard IS-1. Greatbatch Medical has also been involved with the AAMI Pacemaker Connector
Standards Committee that has been working on the new IS-4 connector standard over the past
four years, with the intention of supplying selected IS-4 adapters to the industry once the
connector standard has been determined.
