  • Methods for thread transection of a soft tissue
    Patent number: 10213222
    Abstract: A method and apparatus for transecting soft tissue, such as a ligament, and more particularly, the transverse carpal ligament. A pair of hollow introducer needles can be used to rout a thread-like, smooth and non-abrasive cutting element around tissue, such as a soft tissue, to enable a transection of the soft tissue using minimally invasive techniques. The cutting element is routed into position about the target soft tissue such that the cutting element both enters and exits the body from the same side of the soft tissue. The smooth and non-abrasive exterior surface of the cutting element serves to provide a kerf-less cut.
