• Looking at the timing, I'm thinking there might be a recent product update or manufacturing change. Has there been any significant modification to the Spectra WaveWriter system in the past 6-9 months?

Why it matters: Recent changes could directly correlate with the increase in adverse events. Expected answer: Yes, a firmware update was released 7 months ago. Impact on approach: If confirmed, we'd focus on the firmware update as a primary area of investigation.

• Considering the nature of adverse events, I'm wondering about the specific types of issues being reported. Can you provide a breakdown of the most common adverse events and whether their distribution has changed?

Why it matters: Understanding the nature of the adverse events helps pinpoint potential causes. Expected answer: There's been an increase in reported stimulation inconsistencies and battery issues. Impact on approach: This would guide our technical investigation towards specific components or functionalities.

• Given the medical nature of the device, I'm curious about any changes in regulatory requirements or reporting procedures. Have there been any modifications to how adverse events are defined or reported in the last year?

Why it matters: Changes in reporting could artificially inflate the numbers without an actual increase in incidents. Expected answer: No significant changes in regulatory requirements or reporting procedures. Impact on approach: If confirmed, we'd focus on actual device or user-related issues rather than reporting anomalies.

• Considering potential external factors, I'm interested in market dynamics. Has there been any significant change in the patient population or usage patterns of the Spectra WaveWriter system?

Why it matters: Changes in user demographics or usage patterns could explain the increase in adverse events. Expected answer: There's been a 15% increase in prescriptions for chronic pain patients under 40.
