Information received by medtronic indicated that the customer reported inpen is not working properly, the dose knob/ dial is difficult to turn on and the screw is not moving as intended.Troubleshooting was performed but the issue was not resolved.No harm requiring medical intervention was reported.The customer will discontinue using the device and the device will be returned for analysis.

Manufacturer Narrative

Per visual inspection: no physical damage to cartridge holder or inpen front and back shell was noted.Inpen paired with commercial mobile app with small dose.Received inpen [ 1/4 ] of travel.Performed encoder bond investigation and found that the encoder pattern wheel tabs rotating and traveling off the keyed slots of dose nut guides.Encoder pattern wheel should never rotate.This causes an unexpected travel of the encoder pattern wheel creating resistance to dial and dispensing.Also, plastic shavings contamination builds up found caused by encoder wheel tabs rubbing at the walls of the dose nut.Abrasions down the length of the dose nut.Unable to perform baseline/wireless functionality and displacement dose accuracy test.Performed leadscrew reset torque test.Inpen passed and is within specification (ccw: 5.60ozf-in).Inpen passed front cap investigation.Unable to confirm dose log inaccuracy or leadscrew anomaly due to difficult to dial and dispensing.In conclusion: it was determined from destructive analysis that the difficult to dial/dose was caused by a pattern wheel misalignment due to an encoder base bond failure.This can affect insulin delivery.Therefore, the customer concern of dose dial being difficult to dial/dose was confirmed.Medtronic submits this report to comply with fda regulations 21 cfr parts 4 and 803.Medtronic has made reasonable efforts to provide as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employees caused or contributed to the event described in the report.Medtronic will submit a supplemental report if additional relevant information becomes known.
