Abstract

The present disclosure provides embodiments of an assembly that can be used in a method for improving coaptation of the anterior and posterior mitral valve leaflets by applying a remodeling force to the posterior leaflet. In particular embodiments, the assembly includes an elongate delivery catheter having at least one lumen and an elongate flexible tension member having first and second ends. Thetension member is deployable from the delivery catheter. The assembly further includes a closure member configured to be implanted in the interatrial septum of a patient' s heart, and a deployable fastener configured to be secured on the tension member adjacent to the closure member. Once secured to the heart, tension can be applied to the tension member in a direction superiorly and anteriorly toward the interatrial septum, providing a remodeling force pulling the posterior leaflet superiorly and anteriorly to improve coaptation with the anterior leaflet.

Description

technical field [0001] The present disclosure generally relates to methods for preventing or reducing regurgitation through heart valves and delivery systems and implantable devices useful in such methods. Background technique [0002] The natural heart valves (ie, the aortic, pulmonary, tricuspid, and mitral valves) play a key role in ensuring an adequate supply of positive blood flow through the cardiovascular system. These heart valves may be less effective due to congenital malformations, inflammatory processes, infectious conditions, or disease. Such damage to the valve can lead to serious cardiovascular harm or death. For many years, the definitive treatment for this condition was surgical repair or replacement of the valve during open heart surgery. However, this procedure is highly invasive and prone to multiple complications. As a result, elderly and frail patients with defective heart valves often go untreated. More recently, transvascular techniques have been ...
