<p>A support housing (1) for valve and closure members, in particular for heart valve prostheses, has a base ring (2) which carries at least two symmetrically offset posts (4/5) substantially oriented in the direction of the ring axis and linked together by curved strips (3) for securing at least two flexible webs (6/7). In order to produce with such a support housing a valve or closure member, in particular a heart valve prosthesis, which operates reliably even with different closing pressure differentials, i.e. in particular even under varying physiological stress conditions , the stent (1) is only retained in sections and with limited flexibility. For that purpose the free ends (4) of the posts have a rigid form, and/or the bases of the posts have a flexibility limited by stops, and/or the strips (3) have a flexibility limited by stops.</p> |
