Endovascular micro tools

Endovascular micro tools mean the catheter-like systems with micro devices which are put into arteries and veins. An intravascular micro active catheter system is the most famous type of endovascular micro tools and it consists of active bending catheter and some functional catheters such as guide wire, balloon catheter, angioscope, drug delivery catheters, micro surgery tools and so on. These systems have been widely developed and commercialized. A brief overview of the intravascular micro active catheter is presented, followed by an explanation of the micro systems being developed at the Seoul National University. This system consists of an active bending catheter, micro drug infusion catheter and ultrasound-scanning catheter. All of these systems show the proper functions in in-vivo and in-vitro tests.
