Device for minimally invasive tendon sheath release having static blade

Abstract

A device for minimally invasive tendon sheath release is presented. The device enables a surgeon to cut (“open”) a pulley that is obstructing a nodule and keeping a tendon from sliding smoothly. The device is generally comprised of a sheath having a guide probe and a dorsal outrigger guide between which a cutting blade is positioned. The device is inserted through a small incision and the guide probe is used to find the edge of the pulley. Once found, the probe is guided to an end of the pulley. After proper position is assured, a cutting blade is deployed The entire device is then pushed or pulled using the device handle along the pulley until the pulley is completely released or where resistance is no longer felt.

Dependencies are inferred from the claim text.
