1. A system for releasing a ligament, the system comprising:
- a proximal handle;
an outer tubular body comprising a proximal end and a first portion of a cutting structure, the proximal handle coupled to the proximal end of the tubular body; and
an inner flexible body extending through the outer tubular body and comprising a second portion of the cutting structure,wherein at least one of the inner flexible body or the outer tubular body is longitudinally displaceable relative to the other to combine the first portion of the cutting structure with the second portion of the cutting structure to form the cutting structure when the cutting structure is in a deployed state.

Abstract
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.

24. A medical device for severing tissue in a minimally invasive medical procedure, the device comprising:
-
a tubular body including;
a tubular wall defining an lumen extending longitudinally through the tubular body;
a proximal end;
a distal end opposite the proximal end; and
a window extending through the tubular wall, the window including a length greater than a width of the window, the length of the window being generally parallel with a length of the tubular body;an inner body occupying at least a portion of the lumen and including;
a proximal end;
a distal end opposite the proximal end;
an exterior surface located between the proximal and distal ends of the inner body; and
a plurality of saw teeth defined in the exterior surface and fixed relative to the exterior surface; anda handle coupled to the proximal end of the tubular body, the handle including an actuator coupled to the proximal end of the inner body and configured to displace the inner body within the lumen between a non-deployed state and a deployed state, wherein the plurality of saw teeth bow out of the window when the inner body is in a deployed state. - View Dependent Claims (25, 26, 27)

28. A medical device for severing tissue in a minimally invasive medical procedure, the device comprising:
-
a tubular body including;
a tubular wall defining an lumen extending longitudinally through the tubular body;
a proximal end;
a distal end opposite the proximal end; and
a window extending through the tubular wall, the window including a length greater than a width of the window, the length of the window being generally parallel with a length of the tubular body;a first inner body occupying at least a portion of the lumen and including a proximal end and a distal end opposite the proximal end; a second inner body occupying at least a portion of the lumen at the window and including an exterior surface and a plurality of saw teeth defined in the exterior surface and fixed relative to the exterior surface; and a handle coupled to the proximal end of the tubular body, the handle including an actuator coupled to the proximal end of the first inner body and configured to displace the first inner body within the lumen between a non-deployed state and a deployed state, wherein displacing the first inner body from the non-deployed state to the deployed state causes the second inner body to be positioned between the window and the first inner body such that the saw teeth extend from the window. - View Dependent Claims (29, 30)
