Improved performance of a new thrombus aspiration catheter: outcomes from in vitro experiments and a case presentation.
Thrombus vacuum catheter (TVAC) is a new thrombus aspiration catheter. The catheter has a beak-shaped distal tip and a shaft with spring support. Based on in vitro tests, these design features showed improved ability to pass through a simulated coronary artery model with a bend and to aspirate gel. TVAC has an outer diameter of 4.5 Fr and is available with a 7 Fr guide. We report a case of acute myocardial infarction that was successfully treated with TVAC after use of other aspiration devices failed in its treatment. Since protection of microcirculation in coronary reperfusion may be essential in acute myocardial infarction, TVAC is a promising device to help achieve this goal.
