An esophageal valve (1) comprising a polymeric valve body having an outer support region (2) at least three valve leaflets (3, 4, 5), and a main body region (6) extending between the support region (2) and the valve leaflets (3, 4, 5). The valve (1) has a normally closed configuration in which the valve (1) is closed, an antegrade open configuration in which the valve leaflets (3, 4, 5) are opened in response to an antegrade force to allow flow through the valve (1), and a retrograde open configuration in response to a retrograde force which is substantially larger than the antegrade force.

Le clapet présente normalement une configuration fermée dans laquelle le clapet (1) est fermé, une configuration ouverte antérograde dans laquelle les feuillet de clapet (3, 4, 5) sont ouverts en réponse à une force antérograde pour permettre l'écoulement par le clapet (1), et une configuration ouverte rétrograde en réponse à une force rétrograde qui est sensiblement plus grande que la force antérograde.
