Problems solved by technology

The Mitral Valve Repair System was not intended or designed for use with the tricuspid valve and is not FDA-approved for this indication
Therefore, the use of mitral valve repair systems for the treatment of tricuspid regurgitation is limited to a limited case population where the valve and cardiac anatomy qualify, and may also have issues related to safety and efficacy

Abstract

A tricuspid valve apparatus may include a frame and an associated neo-prosthetic valve. The frame acts as a stabilizing structure that extends cephalad into the morphologic or functional right atrium(upstream) and caudally into the morphologic or functional right ventricle (downstream). The frame comprises a strutted atrial dome that conforms to the atrium without obstruction of blood flow from the incoming great veins (i.e. superior vena cava and inferior vena cava) or other anomalous veins and / or tributaries. The frame further comprises ventricular struts to be placed within the right ventricle to secure the neo-prosthetic valve in a desired position. The assembly of the frame and valve is collapsible so that prior to deployment the assembly is placed in a vascular catheter, and then self-expands upon release in the heart.

Description

technical field [0001] This application relates to the treatment of heart valve regurgitation. Background technique [0002] Cardiac valve regurgitation can cause acute and chronic symptoms (eg, shortness of breath, poor endurance, leg swelling, abdominal discomfort, malnutrition) and considerable morbidity (eg, acute pulmonary edema, heart failure, pulmonary hypertension, organ dysfunction, cachexia , anorexia) and mortality. Open heart valve surgery has proven effective but poses problems related to perioperative mortality and postoperative complications. This traumatic procedure requires a long (months) recovery time after open heart surgery and may not be suitable for many patients. Therefore, there is a need for a less invasive method for treating the tricuspid valve between the right atrium and right ventricle. [0003] Currently, treatment for tricuspid regurgitation involves the use of a valve repair system developed by MitrAlign Systems called TriAlign, which use...
