Patent attributes
An implantable lead is disclosed which includes an elongated lead body having opposed proximal and distal end portions. At least one defibrillation assembly is operatively associated with the distal end portion of the lead body for delivering electrical energy to cardiac tissue. The defibrillation assembly includes a plurality of axially spaced apart conductive hull assemblies that at least partially surround the elongated lead body, and a helically wound shocking coil that extends over the axially spaced apart hull assemblies so that a series of annular void regions are defined by the shocking coil, the lead body, and adjacent hull assemblies, whereby the annular void regions allow the shocking coil to articulate, thereby inhibiting buckling of the shocking coil.
