Stress testing life-saving medical devices: automation and custom integrations to augment production goals.

Challenge

Medtronic puts patient safety first, deploying rigorous quality controls throughout the manufacturing process. In support of its focus on quality, Medtronic puts every device through multiple test procedures. The burn-in test is one step in the quality process used to ensure no unreliable products leave the factory floor.

During the burn-in manufacturing process, factory specialists were manually taking down data and events happening with various devices. This led to inaccuracies and created a ‘hidden factory.’ Medtronic wanted to eliminate the manual entry of data during this process to make it efficient and accurate.

Solution

Valore Partners determined that the solution must include:

  • Custom emulators for oven firmware
  • A custom API to read data from the oven
  • Integration with the oven’s camera system to identify devices and transmit data to the stress test
  • A custom dashboard to organize, catalog and display these data

Valore Partners designed a desktop application with a state machine workflow engine using C# and WCF that kept track of the devices during the manufacturing process in real time.

This application had advanced error handling and notification mechanisms built-in to support a 24/7 schedule.

We conducted multiple tests and analysis using ReSharper dotMemory to eliminate any memory and performance issues.

Our Developers supported the FDA required validation and testing of the software via continuous delivery and unit testing. Applying consistent development practices and diligent testing, the team was able to deliver a solution that was trustworthy.

Outcome

  • Medtronic was able to reduce their manufacturing cost by making the burn-in process faster and easier
  • Medtronic increased their speed to market for critical life-saving devices
  • Medtronic increased their return on investment for custom burn-in ovens by reducing the cost of collecting and analyzing data
