A new patent-pending technology to enhance the fatigue life of biostimulation leads used in devices like pacemakers, implantable cardioverter defibrillators, deep brain stimulators, and spinal cord and peripheral nerve stimulators is under development in Fort Wayne Metals R&D. Conventional leads employ a composite DFT® wire with a 35N LT® alloy shell and a conductive silver core. By replacing the 35N LT® alloy with superelastic or shape memory nitinol, dramatic improvements in strain-fatigue (and presumably service life) can be achieved. A polyimide coating is further applied to the wire, and with proper care can withstand the shape-setting head treatments needed to form nitinol into the desired lead components like cables and coil.
