Intra-vascular vehicle


A vehicle that moves in blood vessels.

Intra-vascular vehicles are intended to move through blood vessels freely, to deliver diagnostic or therapeutic equipment to the diseased part, and to carry out diagnosis and therapy. This vehicle is expected to make a diagnosis and therapy that is less invasive to the patient compared to the conventional surgery or even to the use of catheters. By the use of the vehicle, improvement of diagnostic and therapeutic reliability is also expected. However, it is difficult for the vehicles to move against blood flow or stay in a particular position. Themes to be solved are: in order to pass through peripheral blood vessels, the vehicle must be as small as several micrometers while satisfying other requirements such as flexibility; how to supply energy to the vehicle; and how to recover the vehicle after use.
