Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular intraannular band. The band has a first end, a first anchoring portion located proximate the first end, a second end, a second anchoring portion located proximate the second end, and a central portion. The central portion is positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets. The band may be implanted via translumenal access or via thoracotomy.

Repair of a spine from a posterior approach especially for locating an implant between a lower and upper human vertebra includes making an incision in the skin lateral to the midline, making an incision through the Erector Spinae Aponeurosis (ESA) following the ELIF groove, separating the ESA from the Longissimus Thoracis Pars Lumborum (LTPL), atraumatic separating the Multifidus from the LTPL using the interfascial boundary between the Multifidus and the LTPL, and creating a surgical plane having an angle of 20°-60°.

A retractor for performing surgery, for instance cardiac surgery on the coronary organs of a patient, which has a driving member to which the surgeon input is applied in the form of a mechanical force or torque, a thoracic structure engaging member which interfaces and retracts the patient's thoracic structure when surgeon input is applied to the movable driving member, and a surgeon input load-reducing and load-normalizing mechanism provided in at least one mechanical interface between retractor components where relative motion therebetween occurs. The load-reducing and load-normalizing mechanisms are preferably non-lubricated, thereby tending to ensure an inert and sterile environment during surgery. The retractor is comprised of a locking arrangement allowing a retractor spreader arm to be secured at any longitudinal position along the rack bar, independently of the pinion's position. The thoracic retractor according to this invention tends to improve the efficiency and safety of surgery by reducing the surgeon input required to achieve retraction, and by allowing said input to be applied more uniformly and in a controlled manner free from sudden movements through the normalization of retractor variables.
