Visualization of aspirated flow pathlines in a thrombectomy catheter with three extra holes: A CFD study

摘要

The aspiration catheter design requires the good understanding of blood flow, based on a complex analysis of its hemodynamic characteristics. Computational fluid dynamics (CFD) is an important approach in studying the blood flow. In this paper the effect of extra upper holes - designed for the aspiration catheter - on the aspirated fluid pathlines are studied and discussed.
