The device history record review showed that all acceptance criteria inspections per established sampling levels were within acceptable limits during the production process.There were no deviations and no nonconformances initiated with this lot code.There were no samples submitted with this complaint; however, the complaint will be reopened if a sample is later received.Because no sample was returned with this complaint, no physical product examination was possible to confirm the reported conditions of no reading.Had a sample been received, it would have been evaluated against the established product requirements.A probable root cause could not be determined because no samples were submitted to examine for the reported condition and the complaint could not be confirmed.Current manufacturing practices require production to be sampled and inspected through a series of functional and visual testing based on valid aql sampling plans to ensure good connectivity and shock delivery.Functional testing performed on this product includes but is not limited to electrical properties testing, energy transmission by simulating defibrillation testing, gel weight measurements, pull force testing, and residual monomer testing.Likewise, visual inspections are performed based on aql sampling where construction, alignment, packaging and labeling of product are examined to ensure all product requirements are met prior to release.Production employees also perform 100% visual inspection as part of manufacturing requirements.Since this complaint is unconfirmed and no complaint trend exists and a specific root cause for the occurrence cannot be identified, no corrective action is required at this time.This complaint will be recorded for tracking and trending purposes.
