Method and apparatus for improving mitral valve function

摘要

An apparatus for reducing mitral regurgitation includes a delivery catheter extendable through a vascular system of a patient and into a coronary sinus proximate a posterior leaflet of a mitral valve, the catheter having at a distal end thereof a flexible tubular extension for engaging an opening of the coronary sinus and entering the coronary sinus, a substantially rigid body for advancement through the delivery catheter and to be positioned in the coronary sinus proximate the posterior leaflet, and an elongated rod for advancing the body through the catheter and into position proximate the posterior leaflet.
