Tissue Removal Systems and Related Methods

A tissue removal system comprising:

• a tissue removal device comprising a tissue cutting wire support tube, a tissue cutting tube, one or more tissue cutting wires, a tissue cutting wire actuation mechanism, and a tissue cutting tube actuation mechanism, wherein the tissue cutting wire support tube has a tissue cutting wire support tube lumen, wherein the tissue cutting tube has a tissue cutting tube lumen, wherein the tissue cutting tube is disposed within the tissue cutting wire support tube lumen, wherein the one or more tissue cutting wires are configured to be rotated to cut a tissue, wherein the tissue cutting wire actuation mechanism comprises a tissue cutting wire drive input, wherein the tissue cutting wire actuation mechanism is configured to rotate and outwardly expand the one or more tissue cutting wires in response to rotation of the tissue cutting wire drive input in a first direction, wherein the tissue cutting wire actuation mechanism is configured to rotate and inwardly contract the one or more tissue cutting wires in response to rotation of the tissue cutting wire drive input in a second direction opposite to the first direction, wherein the tissue cutting tube actuation mechanism comprises a tissue cutting tube drive input, wherein the tissue cutting tube actuation mechanism is configured to rotate the tissue cutting tube in response to rotation of the tissue cutting tube drive input, wherein the tissue cutting wire support tube has tissue cutting wire support tube tissue removal openings, and wherein the tissue cutting tube has tissue cutting tube radial openings configured to cooperate with the tissue cutting wire support tube tissue removal openings to chop tissue and allow aspiration of the chopped tissue through the tissue cutting tube lumen;
• a tissue cutting wire drive cable assembly drivingly coupled with the tissue cutting wire drive input;
• a tissue cutting tube drive cable assembly drivingly coupled with the tissue cutting tube drive input;
• and
• a control unit comprising a tissue cutting wire drive output, a tissue cutting wire drive motor drivingly coupled with the tissue cutting wire drive output, a tissue cutting tube drive output, and a tissue cutting tube drive motor drivingly coupled with the tissue cutting tube drive output, wherein the tissue cutting wire drive output is configured to be drivingly coupled with the tissue cutting wire drive cable assembly, wherein the tissue cutting tube drive output is configured to be drivingly coupled with the tissue cutting tube drive cable assembly, wherein the control unit is configured to control operation of the tissue cutting wire drive motor to control rotation, expansion, and contraction of the one or more tissue cutting wires, and wherein the control unit is configured to control operation of the tissue cutting tube drive motor to control rotation of the tissue cutting tube.
