Abstract

Abstract An apparatus is described for supporting and/or constricting a surface of a valve annulus. The apparatus includes a tubular member of dimensions suitable for insertion into a body vessel. The tubular member includes at least two first segments attachable to an interior wall of the body vessel. The tubular member further includes at least one second segment which is capable of decreasing its axial length to draw one of the first segments towards the other first segment.
