For example, medical doctors use medical devices for an endovascular treatment of intracranial aneurysm. The purpose of this medical device is to control blood flow. However, only development is not enough to reach patients. The establishment of evaluation system with safety and objective manner should be necessary. And the training system for the device is also necessary. We try to find out the flow around the medical device or in human organs using CFD (computational fluid dynamics), AI, PIV or ultrasound for velocity distribution using bio-model. The findings could relate to the mechanism of disease or prediction of blood flow. These research activities are performed with medical doctors, medical companies and a venture business company called Blue-Practice.<\/div>\r\n<\/div>\r\n<div class=\"contents\">\r\n<div class=\"wrapper\">\r\n<h4>Development of PVA-H 3D printer<\/h4>\r\n<div>PVA-H has an advantage of mechanically mimicking human organs. We developed a new 3D printer for specific patient shape made of PVA-H. If medical doctors receive a model with the patient specific shape, they can check their procedure of treatment before the real treatment.
