A stent (5) for placement at a vessel bifurcation has an expanded configuration and an unexpanded configuration. The stent comprises a substantially tubular main body (10) and a branch body (30) . The branch body comprises at least one flexible member (35) engaged to the main body. The flexible member comprises an expandable polymer (37) which is actuatable between a high volume state and a low volume state . When in the high volume state the volume of the expandable polymer is greater than in the low volume state. Also, when the expandable polymer is actuated from the low volume state to the high volume state, the branch body is expanded from the unexpanded configuration to the expanded configuration. In the expanded configuration the branch body extends obliquely from the main body.
Endoprothèse (5) destinée à être mise en place au niveau de la bifurcation d~un vaisseau sanguin, offrant une configuration dilatée et une configuration non dilatée. L~endoprothèse comprend un corps principal sensiblement tubulaire (10) et un corps d~embranchement (30). Le corps d~embranchement comprend au moins un élément souple (35) rattaché au corps principal. L~élément souple est constitué d~un polymère extensible (37) susceptible d~être actionné pour occuper un grand volume et un petit volume. Lorsque le polymère extensible est actionné pour passer du petit volume au grand volume, le corps d~embranchement se dilate pour passer de la configuration non dilatée à la configuration dilatée. Dans la configuration dilatée, le corps d~embranchement se prolonge à l~oblique du corps principal.
