Systems and methods for treatment of compressed nerves

A system for releasing a ligament, the system comprising:

• a tubular body comprising:
• a proximal end,
• a distal end opposite the proximal end,
• a tubular wall located between the proximal end and the distal end of the tubular body, the tubular wall defining a lumen extending longitudinally through the tubular wall and comprising an inner diameter and an outer diameter, and
• a window defined in the tubular wall;
• an inner body extending through the lumen of the tubular body and comprising:
• a proximal end,
• a distal end opposite the proximal end,
• a tissue penetration tip at the distal end of the inner body, and
• a tissue cutting portion located between the distal end and the proximal end of the inner body;
• and
• a proximal handle coupled to the proximal end of the tubular body and comprising a first actuator coupled to the inner body, the first actuator configured such that actuation of the actuator causes the inner body to axially rotationally displace relative to the tubular body to transition the tissue cutting portion between a non-deployed state and a deployed state, wherein in the non-deployed state the tissue cutting portion is hidden from the window, and in the deployed state the tissue cutting portion is exposed at the window and remains confined to a boundary defined by the outer diameter of the tubular wall of the tubular body;
• wherein the tissue cutting portion includes a plurality of teeth that extend radially outward from the inner body.
