Abstract
Abstract A valve repair device and method of repair for the mitral valve of the heart is disclosed. The valve repair device includes a leaflet portion, a muscle portion, and a plurality of chords connecting the leaflet portion to the muscle portion. The valve repair device is attached to the diseased valve by suturing the leaflet portion to the affected leaflet and suturing the muscle portion to the affected muscle. The leaflet portion and muscle portion are constructed of cloth made from expanded polytetraflouroethylene. The chords are sutures also constructed from expanded polytetraflouroethylene. The suture position for the muscle portion is determined by positioning the valve repair device adjacent to a normal marginal chord. The valve repair device may be employed to repair the anterior leaflet or posterior leaflet of the mitral valve.
