摘要：
Systems and devices are described which include a tissue cutting device including a central rotatable shaft having a first end and a second end； a motor operably coupled to the first end of the central rotatable shaft, the motor including circuitry configured to rotate the central rotatable shaft； a moveable component configured to move along at least a portion of the length of the central rotatable shaft； and an elongated flexible cutting component having a first end and a second end, the first end of the elongated flexible cutting component secured to the moveable component and the second end of the elongated flexible cutting component secured to the central rotatable shaft in proximity to the second end of the central rotatable shaft； wherein movement of the moveable component along the at least a portion of the length of the central rotatable shaft changes a shape formed by the elongated flexible cutting component.
