Laser flow visualization and particle image velocimetry of flow through scaled intra-arterial filter: in vitro studies

摘要

The use of in-line intra-arterial filters to trap large to mid-size emboli released during interventional procedures such as Percutaneous Transluminal Coronary Angiography (PTCA) has been proposed as a means of reducing events such as stroke andacute coronary syndromes. However, the fluid dynamics of such in vivo filters have not been examined to date. Such information should provide useful information on optimizing filter design to minimize pressure drop and reduce thrombus formation.
