AN IMPLANTABLE INTRACARDIAC DEVICE FOR TREATMENT OF DYNAMIC LEFT VENTRICULAR OUTFLOW TRACT OBSTRUCTION BY PREVENTING SYSTOLIC ANTERIOR MOTION OF THE MITRAL VALVE LEAFLET INTO THE LEFT VENTRICULAR OUTFLOW TRACT

摘要

An implantable intracardiac device (1) to prevent systolic anterior motion of the anterior mitral valve leaflet into the left ventricular outflow tract is described. The device comprises a blocking member (4) configured for implantation within the left ventricle of the heart (2) and in-situ blocking of systolic anterior motion of the mitral valve (Α') into the left ventricular outflow tract (C) when anchored into the left ventricle of the heart. The device may be configured for radial expansion from a contracted orientation suitable for transluminal delivery to the left ventricle of the heart within a suitable delivery vehicle and an expanded orientation suitable for deployment within the left ventricle of the heart. The device comprises anchoring means (5, 6) configured for anchoring the device in-situ within the left ventricle to a wall of the left ventricle.
