tissue the anode ring 50 or 350 is electrically active and completes the electrical circuit it is typically formed of a polished platinum alloy with an exposed surface area much larger than that of the electrode 45 in fig2 or helix electrode 330 in fig3 sealing rings 95 and 90 as in fig2 both serve to prevent entry of body fluids into the lead assembly and prevent electrically shorting by a conductive fluid they also mechanically stabilize the lead within the pacemaker connector block the proximal end of the lead body is the same for both the fig2 external torque indicator embodiment as for the fig3 internal torque indicator embodiment sealing rings can be affixed with a variety of methods one of which follows the first sealing ring 95 lies over the top of a crimp tube to which the inner spring coil 15 or 315 is connected the inner spring coil is also connected to the pin 60 the first sealing ring 95 prevents shorting by a conductive fluid path from the pin 60 to the connector ring 70 the second sealing ring 90 lies over the top of a crimp tube to which the outer spring coil is connected the second sealing ring prevents shorting by preventing a fluid path between the body tissue and the connector ring 70 the preceding specific embodiments are illustrative of the practice of the invention it is to be understood however that other expedients known to those skilled in the art or disclosed.
