摘要 |
<p>A heart valve prosthesis and a method of fabricating the same. The heart valve prosthesis uses a leaflet of pig pericardium (10) or a leaflet of cattle pericardium, which has a suitable thickness according to the size of the valve, and a stent. The heart valve prosthesis is fabricated by placing a valve body over a Dacron body (20), binding the valve body to the Dacron body using stitching fiber (30), rolling the Dacron body into a cylindrical form such that the valve body is located inside, binding opposite edges of the Dacron body to each other using stitching fiber, and inserting the resultant structure into a stent (60), which is knitted using a shape memory alloy wire. The heart valve prosthesis is friendly to and is not rejected by human tissue, is free from deformation, and can be implanted using a non-invasive manner without incising the chest wall of a patient.</p> |
