Outline of Final Research Achievements

In intraarterial therapy for pancreatic cancer, which has complicated arterial anatomy and hemodynamic, a new device of repeatable microcatheter accessible port was developed. The developed device was tested in in vitro experiments using a vascular model. Then, in vivo study using a pig was conducted. A mcirocatheter was successfully inserted into the hepatic arterial branches through the device. The feasibility of this treatment was shown.
