Event Description
|
It was reported that the patient experienced difficulty charging their deep brain stimulation (dbs) implantable pulse generator (ipg).The physician believes that the ipg may have malfunctioned when the patient had a different surgery last month and the ipg was put into mri mode.It was unknown if electrocautery was used during the previous procedure.After trying a new remote control and charger, the ipg still did not charge.The patient underwent a revision procedure and the ipg was explanted and replaced.The patient was doing well postoperatively.

Manufacturer Narrative
|
The reported event of the patient experiencing difficulty charging their dbs ipg was confirmed through technical analysis of the returned device.The ipg passed visual inspection and was unable to recharged.It was cut open and it was revealed that the battery exhibited a high sleep current.Electrical testing revealed a low resistance measurement, which indicates an electrical short within the application-specific integrated circuit (asic).The damaged asic resulted in the premature battery depletion post implant.This type of damage is typically caused when the ipg is exposed to high voltage/current transients or high radiofrequency (rf) energy.Exposure to electrocautery can cause this type of damage.It is unknown if electrocautery was used during the surgery.A labeling review was performed and did not reveal any anomalies as the instructions for use (ifu) states that patients implanted with the full vercise pc dbs system (dbs leads, lead extensions, and stimulator) should not be subjected to magnetic resonance imaging (mri).Mri exposure may result in the following: dislodgement of implanted components and/or damage to the stimulators electronics.
