DGIST research team succeeded in developing a microrobot that can reach the accurate location of cardiovascular disease such as the Chronic Total Occlusion by moving and steering the microrobot towards a desired direction inside complicated blood vessels.

This research is expected to increase the success rate of treatment and shorten the time of cardiovascular disease surgery.

DGIST announced on February 27 that Professor Hongsoo Choi's team in the Robotics Engineering Department developed the 'Magnetically Controlled Microrobot' that can enhance the success rate of CTO treatment among myocardial infarctions through a joint research with Professor Byung-Ju Yi's team at Hanyang University and Professor Bradley J Nelson's team at idgenössische Technische Hochschule Zürich in Switzerland.

Since the guidewire used for percutaneous coronary intervention , which opens up the obstructed blood vessels, is controlled manually by a surgeon to change its direction and location, the success rate and speed of surgery had depended on the surgeon's skill.

To overcome this limitation, Professor Choi's team applied flexible and biocompatible polymer as well as neodymium magnet that can control the direction and location with as external magnetic field.

Using this, the team developed a cylindrical microrobot with a diameter of 500?
