Method and apparatus for controlled contraction of soft tissue
First Claim
1. An orthopedic apparatus for delivering RF energy to ligaments, joint capsules and connective tissue to effect the controlled contraction of collagen fibers, the apparatus comprising:
- an orthopedic electrode including an electrode proximal end and an electrode distal end, the distal end including an energy delivering distal electrode portion comprising a tip having a generally planar surface with the periphery of the planer surface curving into a depending wall with radiused edges for delivering substantially uniform energy across the surface of the energy delivering distal electrode portion to an area of collagen fibers adjacent to the electrode to cause a controlled amount of contraction of the collagen fibers while minimizing dissociation and breakdown of the collagen fibers and minimizing ablation of tissue neighboring the collagen fibers;
a handpiece connected to the electrode proximal end for enabling the energy delivering portion of the electrode to be moved relative to the collagen fibers to be contracted during the application of thermal energy;
an RF energy source; and
a cable to connect the RF energy source to the handle and the electrode.

Abstract
An apparatus and method are provided for control contraction of tissue that includes collagen fibers. The apparatus includes a handpiece, and an electrode with an electrode proximal end associated with the handpiece. A distal end of the electrode has a geometry that delivers a controlled amount of energy to the tissue for a desired contraction of the collagen fibers. This is achieved while dissociation and breakdown of the collagen fibers is minimized. The handpiece, with electrode, is adapted to be introduced through an operating cannula in percutaneous applications. Additionally, an operating cannula may be included in the apparatus and be attached to the handpiece. The apparatus and method provides for a desired level of contraction of collagen soft tissue without dissociation or breakdown of collagen fibers.
