Abstract

The invention relates to a heart implant comprising a tubular attachment element (1) for attaching an inflatable membrane (2), particularly an inflatable membrane (2) being coaxially positioned around the tubular attachment element (1) and fixed to it, the tubular attachment element (1) at one of its ends being split into several strips (4), the strips (4) extending away from the tubular attachment element (1) and forming an expandable cage (C), particularly for fixing the heart implant to the atrium of the heart by surface contact between an exterior surface of the expandable cage (C) and an interior atrium surface, each one of the strips (4) being split into two branches (4a, 4b, 4a′, 4b′, . . . ), each respective branch (4a) being merged into a new strip (5) together with another respective branch (4b′) of a neighboring strip (4) wherein such splitting and merging is performed one after the other at least three times and the number of strips (7) being formed of the last merged branches (6a, 6b, . . . ) at the end of extension corresponding to the number of strips (4) at the one end of the tubular attachment element (1).
