MASACATH has designed and built a catheter angle measuring device for Biosense Webster. A cardiac catheter is a surgical tool that resembles a flexible tube-like structure. This surgical tool is guided into the heart via a patient’s vein. Doctors often use cardiac catheters in heart surgeries to diagnose and treat patients with heart diseases. Precise rotation of the catheter tip is critical during these surgeries to avoid any harm to the patient's heart. Due to this need for rigid control of the tip, we designed a device that evaluates the rotation of a catheter’s body. The main goals of our measuring device are to find if the rotation of the handle and tip are in line and to analyze any angle differences between them in real-time. To achieve this, our device rotates the catheter’s handle to a specific angle and then measures the resulting rotation of the tip, using sensors.
Our design has two separate sensor modules. One module is for the catheter tip while the other is for the catheter handle. A motor controls the rotation input to the handle. A gyro motion sensor confirms the rotation angle of the handle, while a magnetic sensor reads the rotation of the tip. We connect the two sensors with an Arduino and display the angle readings of both the catheter tip and the handle on a screen. To restrict the catheter’s motion during testing, we placed it inside a tight rubber cover. This cover simulates the walls of a human vein. We aim to expand the range of catheter testing by building a measuring device with a mounted outer tube, motor, angle sensors and baseboard. Performance tests confirmed sensor accuracy by making baseline and visual measurements. Our device can detect small differences in rotation angles, which will be a major advantage for doctors during surgeries.
The next step is to conduct further tests to optimize the efficiency and effectiveness of the device and determine its potential for widespread use as a measuring device. This includes assessing its effectiveness and cost-effectiveness and addressing limitations such as the lack of consideration for time delaying effects. The future work also involves exploring potential improvements in design and control, as well as investigating new technologies that could enhance the performance of the device.
