Thermal cutting-assisted tissue resection devices and systems

A tissue resection device, comprising:

• a handpiece;
• and
• an end effector assembly extending distally from the handpiece, the end effector assembly including:
• an outer shaft including a window defined therethrough towards a distal end thereof;
• an electromagnetic induction coil disposed on or embedded within the outer shaft, the electromagnetic induction coil adapted to connect to a source of energy to produce an electromagnetic field within the outer shaft;
• an inner shaft rotationally disposed within the outer shaft, the inner shaft operably coupled to the handpiece such that the handpiece is capable of rotationally driving the inner shaft relative to the outer shaft;
• and
• a cutting element disposed at a distal end portion of the inner shaft within the outer shaft and at least partially overlapping the window and the electromagnetic induction coil, the cutting element configured such that rotation of the inner shaft rotates the cutting element, the cutting element formed at least partially from a ferromagnetic material capable of being inductively heated by the electromagnetic field produced by the electromagnetic induction coil.

• and
• a plurality of electromagnetic induction coils, each electromagnetic induction coil of the plurality of electromagnetic induction coils disposed about an arm of the plurality of arms, each electromagnetic induction coil adapted to connect to a source of energy to produce an electromagnetic field therewithin to thereby inductively heat the corresponding arm of the cutting element.
