Case Study: WOM reduces time-to-market for surgical device control software with MathWorks

WOM Reduces Time-to-Market for Surgical Device Control Software with Model-Based Design

WOM, a world market leader in insufflator and pump technologies for laparoscopy and hysteroscopy, faced the challenge of delivering exceptionally reliable, IEC 62304‑compliant control software while shortening time-to-market and reducing onboarding time for new engineers. Using MathWorks’ Model-Based Design approach with MATLAB and Simulink, WOM sought to move away from hand-written code that delayed defect discovery and slowed deliveries, and to meet FDA and German regulatory requirements for medical device software.

Working with MathWorks tools (including System Identification Toolbox, Stateflow, Simulink Coder, Embedded Coder, and Simulink Check), WOM built a nonlinear plant model, implemented cascaded PI controllers and state-machine logic, validated designs via closed-loop simulation and rapid control prototyping (RCP), and generated optimized production code for an Arm Cortex‑M processor. The result: improved software quality with fewer manual coding errors, a single model used for simulation, RCP and production, faster onboarding of new hires, successful FDA and German approvals, and a faster path to market for the new insufflator.
