Question 1

A medical device manufacturer, following a series of customer complaints regarding inconsistent performance of their implantable sensor, initiated a CAPA. The root cause analysis identified a subtle variation in a critical component\'s manufacturing process. The corrective action involved updating the process parameters and retraining the operators.

Which of the following best describes the deficiency in the CAPA process as per ISO 13485:2016?

Accepted Answer

Failure to adequately verify the effectiveness of the implemented corrective action in preventing recurrence of the nonconformity.

Question 2

Following a critical nonconformity identified during the final inspection of a Class II implantable device, a comprehensive CAPA was initiated. The root cause analysis pointed to a specific calibration drift in a critical measurement instrument used during a key manufacturing step. The CAPA involved recalibrating the instrument, updating the calibration procedure to include more frequent checks, and retraining the personnel responsible for calibration. To verify the effectiveness of this CAPA, which of the following approaches would provide the most robust assurance that the nonconformity will not recur and that the underlying issue has been resolved?

Conducting a series of controlled production runs using the recalibrated instrument and verifying the measurement results against established specifications through independent testing and documented review of the calibration logs.

Question 3

A medical device manufacturer producing advanced diagnostic imaging equipment identifies a pattern of intermittent signal degradation reported by several end-users across different geographical regions. Subsequent internal investigations reveal that the degradation is linked to a specific component\'s performance variability under certain environmental conditions, which were not fully simulated during initial product validation. This variability has not yet resulted in a product recall or a formal regulatory non-compliance notification, but the potential for such events is recognized. Which type of action is most critically required by ISO 13485:2016 to address this situation, and what is the primary objective of that action?
