Methods, systems and devices for carpal tunnel release
First Claim
1. A system for cutting a carpal ligament of a patient, the system comprising:
- a probe configured to be advanced into a patient;
a tissue modification device, wherein tissue modification device comprises;
a proximal handle, at least one tissue modification element configured cut the ligament, a sharp distal tip, wherein the sharp distal tip is configured to be advanced anterior to the ligament of a patient and posteriorly through the skin of the patient such that it exits the patient;
a distal handle configured to couple to the sharp distal tip of the tissue modification device; and
a sheath configured to limit the exposure of the tissue modification element of tissue modification device, wherein the tissue modification device is configured for placement within the sheath such that tissue modification element is locally exposed by the sheath, further wherein the probe is a cannulated probe and the tissue modification device is configured to be deployed through the cannulated probe.

Abstract
Described herein are methods, systems and devices for cutting a ligament of a patient. In some embodiments, the method may include the steps of advancing a cannulated probe into a patient, advancing the distal end of the tissue modification device assembly posteriorly through the skin of the patient such that it exits the patient, exposing at least one tissue modification element of the tissue modification device assembly, and reciprocating at least a portion of the tissue modification device assembly by alternately pulling on proximal and distal portions of the tissue modification device assembly to draw the at least one tissue modification element across the ligament to cut the ligament, in some embodiments, the system may include a probe, a tissue modification device, and a sheath. The tissue modification device may include a proximal handle, at least one tissue modification element configured cut ligament, and a sharp distal tip.
