Patent ID: 8608763

Claim:
A method for minimally invasive tendon sheath release, comprising the steps of: injecting a local anesthetic at the level of a A-1 pulley in a finger; making an incision at, or just proximal to, a proximal flexion crease of the finger; providing a device for tendon sheath release comprising: a handle having a cavity; a sheath having a distal end and projecting from the cavity and the handle; the distal end of the sheath having a top and bottom portion; a spherical-tipped guide probe attached to the bottom portion of the distal end of the sheath; a spherical-tipped dorsal outrigger guide attached at the top portion of the distal end of the sheath; and a static blade disposed between the guide probe and the dorsal outrigger positioning the spherical tipped guide probe under an edge of the A-1 pulley in the finger; pushing the device along the A1 pulley in the finger to engage the static blade to release the pulley; and removing the device by backing it out of the incision.
