Event or Problem Description
It was reported that during a procedure to replace the right implantable pulse generator (ipg), the new battery was tested and found to have high impedances (over 40,000) on contacts zero and three.Impedances were checked multiple times on both the old and new batteries, with high values consistently observed on contacts zero and three.To rule out a defective generator, a second new battery was opened and tested; however, high impedances persisted on the same contacts.The patient¿s battery was programmed using contacts one and two, which had normal impedances.The issue was resolved by using the functional contacts, and no further information is available from the healthcare professional.The event occurred during the ipg replacement procedure.No patient complications have been reported as a result of this event.
