Robotically Assisted Surgical Catheter

Project Summary

Positional sensing is crucial for precise placement, navigation, and real-time feedback in catheter-based medical treatments. Utilizing Radwave’s customizable electromagnetic tracking platform, positional sensing was incorporated into an electro-mechanical system in which motors steer the distal end of the catheter.

Design Goal

This project aims to create a proof of concept for an electromechanical surgical catheter that helps not only the patients but also the surgeons. It aims to streamline the surgical procedure by reducing the surgeon’s effort to reposition the distal end of the catheter during the operation. This device also aims to reduce the time the surgeon spends in the operating room and allow full control of the catheter post insertion. As
for the patients, precise movements and locational tracking increases the success of the minimally invasive surgery.

Design Constraints

• Distal End Movement: Maneuver the distal end using a control system.
• Distal End Locking: Lock the distal end at the desired position and automatically return to the same position if moved.
• Catheter Insertion: The ability to insert a range of catheters (8 Fr – 18 Fr) into the 24 Fr guide sheath without displacing the distal end of the guide sheath.
