Abstract
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.
