This is a case of premature insulation failure in an implantable cardioverter defibrillator wire. Below is a gross picture of the failed wire.
Many studies have been done on this ICD, which is called the Riata from St. Jude Medical, Inc, and have shown that insulation failure occurs in up to 33% of patients, of which 29% have electrical problems. One article here showed that out of an FDA database of 133 deaths associated with Riata, Riata ST and Quattro secure leads, 22 (17%) were associated with Riata or Riata ST lead failure.
