Especially, the artificial vascular null multiple pleats in order displacement the aorta segment

摘要

state [Problems] shape change, and to avoid buckling in particular, has been ported in transplantation states of internal pressure, especially to provide an artificial blood vessel to maintain a total flow cross-section substantially. [SOLUTION] The present invention artificial blood vessel in the form of a flexible tube of pleated with (3) folds, on artificial blood vessels to replace the aortic segments near the heart, especially, the tube is in an arc is formed, the shape of the arc is stretch-resistant fixed by growth in non-transplant limiter state.
