DISPOSITIF MÉDICAL, PROCÉDÉ DE COMMANDE DE ROTATION DU DISPOSITIF MÉDICAL, ET ÉQUIPEMENT DE COMMANDE DE ROTATION

摘要

To provide a medical device that can effectively destroy an object in a biological lumen, a method for controlling rotation of the medical device, and a rotation controller. A medical device (10) to be inserted into a biological lumen to destroy a thrombus B in the biological lumen includes a long shaft portion (20) that is rotationally driven, a drive unit (71) that rotates the shaft portion (20), a breaking member (60) that is provided at a distal portion of the shaft portion (20) and is rotatable, and a control unit (100) that controls the rotation of the drive unit (71), in which the control unit (100) controls the drive unit (71) so as to repeat the rotation while interposing a stop of the rotation inbetween.
