1. A medical device for implantation in a body vessel, comprising:
- a support structure having compressed and expanded configurations, a lengthwise axis, first and second opposing sides relative to the lengthwise axis, a first support structure portion positioned on the first side, and a second support structure portion positioned on the second side and distal to the first support structure portion, the support structure defining a lumen; and
first and second flow-deflecting members attached to the support structure;
the first flow-deflecting member having a first edge attached to the first support structure portion and a second edge free of the support structure, the first flow-deflecting member movable between first and second positions;
the second flow-deflecting member having a third edge and a fourth edge, the third edge attached to the second support structure portion such that the third edge is positioned distal to the first support structure portion and the first edge of the first flow-deflecting member relative to the lengthwise axis of the support structure, the fourth edge being free of the support structure;
the second and fourth edges extending across the lumen and creating a central orifice;
wherein retrograde flow in said body vessel contacts the first flow-deflecting member and urges the first flow-deflecting member into the second position to contact and substantially seal against the second flow-deflecting member; and
wherein a portion of the second edge of the first flow-deflecting member is positioned opposite the first edge of the first flow-deflecting member and a portion of the fourth edge of the second flow-deflecting member relative to the lengthwise axis of the support frame when the first flow-deflecting member is in the second position.

Abstract
The disclosure relates to a flow-deflecting medical device comprising a support structure and two flow-deflecting members attached to the support structure. The first flow-deflecting member is movable to a position in which it contacts and substantially seals against the second flow-deflecting member.
