Project Overview
This project focused on the design and development of a realistic catheterization simulation model used to validate and demonstrate a medical device that tracks catheter tip position using internal ECG signals. The product determines when the catheter reaches the correct location near the heart by correlating internal ECG measurements with external reference signals.
The challenge was to create a physical system that could replicate physiological conditions in a controlled, repeatable environment, enabling both engineering validation and non-technical product demonstration. The system needed to accurately simulate catheter insertion, generate corresponding signal responses, and be intuitive enough for use by marketing teams and non-engineers.
Design & System Integration
I led the development of a full-scale chest cavity simulation model, designed to mimic the mechanical and functional aspects of vascular catheterization.
The system incorporated:
-
A realistic anatomical structure to guide catheter motion
-
Integrated flow-triggered sensors positioned to simulate key anatomical locations
-
A signal generation system that produced corresponding internal ECG changes when the catheter reached specific regions
As the catheter was advanced through the model, the sensors (numbered in the picture) triggered changes in the simulated internal ECG signal, allowing the device to track tip position in real time. The system was connected to an embedded laptop running the device software, enabling live visualization of signal behavior and device response.
A major focus was system-level integration, ensuring seamless interaction between mechanical components, sensors, and software. I worked closely with electrical engineers, the shop floor, and marketing teams to define requirements, fabricate components, and ensure the system met both technical and usability goals.
Validation, Usability & Impact
Beyond technical functionality, a key requirement was ensuring the system could be easily operated and maintained by non-technical users. I designed the packaging and system layout to be intuitive, allowing marketing and field teams to quickly set up, troubleshoot, and demonstrate the system without engineering support.
The final system served as both a validation platform and a marketing tool, enabling controlled testing of device performance while also providing a compelling demonstration of the product’s capabilities in a realistic setting. It bridged the gap between engineering development and product communication, ensuring consistency between how the device performs and how it is presented.
This project highlighted the importance of designing systems that are not only technically accurate, but also accessible, reliable, and aligned with real-world use cases across multiple stakeholders.
