Abstract
A defibrillation electrode fabricated by molding an elongated electrode core taking the form of two parallel segments each defining several sigmoidal curves, sliding a conductor coil over and along the electrode core, coupling the electrode coil to an elongated conductor, molding bridging members to connect the two segments of the core at spaced locations along the segments and molding a transition member to the electrode assembly at the junction of the electrode coil and the elongated conductor. The resulting electrode is particularly adapted for use as an epicardial defibrillation electrode, and displays flexibility within the plane defined by the electrode body as well as for twisting and other deformation to follow the changing surface of the heart during contractions.
