Our team will design a novel torque device that allows the user to easily load, unload, and rotate the guidewire using one hand.

Project Overview

Interventional, endovascular, and cardiac catheterization procedures all involve the use of small instruments for minimally invasive treatment. Guidewires are used to navigate blood vessels during procedures and act as guides for larger catheters. The insertion of the guide wire is controlled by a torque device, which allows the surgeon to advance, rotate, and grip the guidewire. Because the torque device is introduced through the far end of the guidewire, some 180-300 cm away from the operation site, it requires the assistance of another individual, often a surgical technician. Current torque devices require the surgeon to use two hands to control the tightening, advancing, and loosening of the device. This project aims to create a clip-on torque device that would enable the surgeon to easily place the torque device along any location on the guidewire and rotate the wire with one hand. This would eliminate the need for pass-through maneuvers and save critical operation time.
