Abstract

La invención proporciona un dispositivo de aterectomía rotacional que tiene, en varias modalidades, un eje de transmisión flexible, agrandado, giratorio con un sistema de cabezales de desgaste excéntricos unidos al mismo. Al menos parte de los cabezales de desgaste agrandados excéntricos en el sistema tienen una superficie removedora de tejido - normalmente una superficie abrasiva. En ciertas modalidades, los cabezales de desgaste pueden ser al menos parcialmente huecos. De preferencia, los cabezales de desgaste agrandados excéntricos tienen centros de masa separados radialmente del eje de rotación del eje de transmisión, facilitando la capacidad del sistema de cabezales de desgaste excéntricos para trabajar juntos para abrir la lesión estenótica a un diámetro substancialmente mayor que el diámetro de descanso exterior de los cabezales de desgaste agrandados cuando se operan a altas velocidades. Por lo tanto, ciertas modalidades comprenden un sistema que tiene centros desbalanceados de masa para no solo estimular mayores diámetros de rotación sino también arreglados en una manera por la cual ocurre un efecto de barrena removedor de desechos. De manera alternativa, otras modalidades pueden comprender sistemas que tienen cabezales de desgaste con centros de masa balanceados.
