Systems and methods for treatment of compressed nerves

摘要

Disclosed herein is a system for releasing a ligament. In one embodiment, the system includes a proximal handle, a tubular body, and a flexible body. The tubular body includes a proximal end and a distal end. The handle is coupled to the proximal end. The flexible body extends through the tubular body and includes a tissue cutting portion. The flexible body or tubular body is longitudinally displaceable to move the tissue cutting portion between a non-deployed state and a deployed state.

1. 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 defining a lumen extending longitudinally through the tubular body and comprising an inner diameter and an outer diameter, anda window extending through 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, anda 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 rotatable actuator coupled to the inner body and configured to rotationally displace the inner body relative to the tubular body to rotationally 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 within a boundary defined by the outer diameter of the tubular wall of the tubular body.
