Helical anchor implantation

Abstract

A method, for use at a mitral valve of a heart of a subject, is provided which includes advancing a transluminal sheath into a femoral vein of the subject, through an inferior vena cava of the subject, into a right atrium of the subject, and transseptally into a left atrium of the subject. A surrounding-sheath is advanced out of a distal end of the transluminal sheath, into the left atrium, and toward a commissure of the mitral valve. An anchor is implanted by advancing the anchor out of the surrounding-sheath into a left ventricle of the subject, such that the anchor helically wraps around left ventricular mitral valve tissue. The surrounding-sheath is then extracted from the heart and then, a guide wire is advanced through the transluminal sheath. Other embodiments are also described.
