A system for impedance characterization of coronary stents
… limited number of time points. The technique of impedance spectroscopy may allow the non-invasive measurement of endothelial cell growth on coronary stents. This project therefore sought to measure the in vitro impedance of a range of coronary stents. Impedance values were recorded from stainless …
