Abstract

such as particle image velocimetry to test endovascular devices as part of an undergraduate biomedical engineering curriculum. Students deployed an endovascular stent into an anatomical model of a cerebral aneurysm and measured intraaneurysmal flow velocities with HemoFlow before and after. The measurements were used as a basis for teaching biofluid mechanical principles. A detailed survey-based evaluation was administered before and after the curriculum. The pre- and post-survey passed reliability testing with Cronbach’s alphas of 0.79 and 0.78, respectively. Further, the survey passed validity testing as questions testing the same latent variable factored together with weights all above 0.4. There was a statistically significant improvement in understanding according to a Wilcoxon signed ranks test. Our results indicate that using HemoFlow for endovascular device testing in an active learning-based curriculum improved student understanding of bio fluid mechanics.
