Additional information was received that the patient underwent generator and lead replacement surgery on (b)(6) 2015 due to prophylactic generator placement and high impedance. Pre-operative diagnostics showed normal impedance, although it was confirmed that diagnostics during the prior office visit showed high impedance at 5356 ohms. The surgeon also identified two visible breaks in the lead insulation during the surgery. The generator and lead replacement surgery was completed. Additional information was received that the explanting facility will not return explanted devices to the manufacturer for analysis; therefore, no analysis can be performed.
