Reason/Issue |
As of December 31, 2012, 30 cases of internal insulation breach under the RV or SVC defibrillation coil have been confirmed by the analysis conducted on returned products. In each of the 30 identified cases, the internal insulation breach of the silicone lumen was observed under the RV and/or SVC defibrillation coil, i.e. where the microcables are not coated with ETFE, resulting in a contact between the conductors, thus leading to low pacing impedance and/or ventricular oversensing, and/or inappropriate therapy. It should be noted that in case of ventricular oversensing, pacing is inhibited. |
