Systems and Devices for Cutting Tissue

A tissue cutting device comprising:

• a tethering component,
• an elongated flexible cutting component having a first end and a second end, the first end and the second end of the elongated flexible cutting component secured to the tethering component;
• at least one tether having a first end and a second end, the first end of the at least one tether attached to the elongated flexible cutting component at a position between the first end and the second end of the elongated flexible cutting component, the second end of the at least one tether operably coupled to the tethering component, the tethering component including circuitry configured to at least one of extend and retract the at least one tether;
• and
• a motor operably coupled to the tethering component, the motor including circuitry configured to rotate the tethering component and the secured elongated flexible cutting component;
• wherein extension and retraction of the at least one tether by the tethering component changes a shape formed by the elongated flexible cutting component.
