摘要: Thin-film transmural cardiac multielectric arrays were fabricated using integrated-circuit processing techniques. Improvements over conventional handmade arrays, such as a smaller cross-sectional area, larger number of recording sites per needle, more accurately controlled size and spacing the sites, bipolar spacings, higher throughput yield, allow for density closely spaced electrodes capable monitoring complex voltage gradient fields present during ventricular fibrillation defibrillation. Both rigid flexible used in acquisition electrical signals. In vitro vivo testing thin-film multielectrode indicates that there are no adhesion or delamination problems, implantation difficulties, unipolar recordings normal sinus rhythm injury potentials similar to those obtained electrodes. >
