3. Figure 2
Cross sections of 8-F silicone Riata single-coil (A) and dual-coil (B) high-voltage implantable cardioverter-defibrillator leads. The cables are coated in ethylene-tetrafluoroethylene, which are shown in blue, and the central coil pace-sense conductor with a stylet lumen is encased in a tube of polytetrafluoroethylene, which is shown in green. Arrows indicate location and direction of inside-out abrasion.
