バルーンカテーテルの引張変形挙動と理論モデルの構築

抄録

Balloon catheters have successfully been used in both cardiology and cardiovascular surgery. However, it has been reported that the fracture of a balloon catheter can be occurred when it is inserted into a small blood vessel with severe arteriosclerosis and stucked due to the calcified endothelial. It is therefore important to understand the tensile deformation and fracture behaviors of balloon catheters. In this study, the tensile deformation behaviors of two different balloon catheters were characterized and the theoretical models were developed to predict the load-displacement curves.
