Key Technologies of Cardiovascular Medical Devices Surface Modification

      The research team of SWJTU has developed the Titanium oxide film with good blood compatibility and functions of promoting  endothelia  cell  growth  and  vascular  tissue normalization，and  uncovered  the  anticoagulation mechanism of biomaterials. Such achievements have been applied  on  the  surface  modification  of  cardiovascular medical devices such as vascular stent, artificial heart valve and artificial heart assist pump.
