摘要：
A cardiac transvenous defibrillation lead has a continuous coil conductor within a layer of insulation. A portion of the coil conductor is exposed as a defibrillation electrode. In order to enhance fluoroscopic visualization of the exposed electrode during implant, the end of the exposed electrode is marked with a radiopaque element. The element may be in the form of an adhesive filled with radiopaque material that is used to backfill under the layer of insulation. Alternatively, a tube made of radiopaque material may be installed between the layer of insulation and the coil conductor.
