113: Biosense Webster (Multidisciplinary Team)

We created a device for Biosense Webster to establish a normalized relationship between the proximal and distal ends of cardiac catheters, in order to control the quality. Our primary focus was to improve Biosense Webster’s current testing arena for catheters and create controlled testing conditions replicating the human body, with limited storage space. Key user design needs included uniform dial movement, repeatability, recording catheter tip movement and data storage. Design inputs translate these needs into specific requirements, emphasizing precise dial movement
and accurate data collection. The current design comprises two main modules, a communication interface and a testing arena replicating internal body conditions.

The proximal-end uses a step motor and Arduino, while the distal-end features an acrylic box with cameras. The testing arena incorporates biomaterials mimicking blood flow and stabilizes components on a board for easy storage. We conducted experiments, generated concepts and selected a modular wooden frame with an acrylic box for the distal end. Stepper motors controlled by Arduino ensure reliable experimentation. Future teams working on this project could build a prototype, address potential issues related to compactness, image processing and mold creation, and explore alternative measuring methods.
