The interventional procedure is a percutaneous treatment modality using various devices such as a guide-wire and a catheter under a minimal incision. It is usually done under a fluoroscopy (X-ray radiography) guidance, therefore the operator would be exposed to X-ray irradiation. Recently, a new procedure using a master-slave robotic system is proposed for the intervention procedure, especially in the era of vascular disease. Many state of art intervention robots are under development and this approach can drastically reduce radiation exposure by replacing human effort by a robotic system for high radiation exposure procedures. However, robotic intervention is still more expensive and needs more efficient end effector and easier human interface for a safer and faster procedure. This article provides a comprehensive summary of vascular intervention and necessity of the vascular intervention robot system.
