Abstract: An orthopedic apparatus, for effecting a change in ligaments, joint capsules and connective tissue through the controlled contraction of collagen fibers, includes a trocar. The trocar has a trocar elongated body with a trocar longitudinal axis, a trocar distal end that is laterally deflectable relative to the trocar longitudinal axis, and a trocar proximal end. An electrode is positioned at the trocar distal end. The electrode delivers substantially uniform energy across an energy delivery surface of the electrode. The energy delivery surface is positioned next to an area of collagen fibers to cause a controlled amount of contraction of the collagen fibers while minimizing dissociation and breakdown of the collagen fibers. A handle is positioned at the proximal end of the trocar. The handle includes an actuating member and a locking member.

Abstract: A surgical heating probe, comprising a handle, a radio-frequency-shielded neck extending from the handle and having an unshielded cathode and an unshielded anode present in the neck with a shielded insulating section of the neck located between the cathode and the unshielded anode, the neck being formed so that three points located in the cathode, the anode, and the insulating; section, respectively, form a triangular plane, the cathode, the anode, and the insulating section being spaced apart at distances adapted so that the cathode and the anode can closely approach opposite sides of an animal tendon, and an energy connector fixture located in the handle and adapted to connect a supply of heating energy to the anode and the cathode. The probe is particularly useful for the treatment of strabismus, and the invention involves the use of radio frequency heating to shrink extraocular tendons in the treatment of strabismus.
