Claim:
1. A valve implant for implantation in a bodily lumen, the implant having a central axis, a proximal end, and a distal end, the implant comprising: a first set of resiliently deformable, elongate members, each having respective proximal and distal ends, the proximal ends adjacent to one another, and respective distal ends flared radially outward, and wherein a plurality of the first set of resiliently deformable, elongate members each have a portion with a concave curvature that smoothly adjoins a portion with a convex curvature; a second set of elongate members, each having respective proximal and distal ends, the proximal ends adjacent to the proximal ends of the first set of elongate members, and the distal ends being free and both flared radially outward and distal to the distal ends of the first set of elongate members; a substantially fluid-tight hood affixed to the first set of elongate members, the hood and first set of elongate members forming a concavity; wherein at least part of the hood is collapsible toward the central axis when blood flows in a direction generally from the proximal end to the distal end, thereby allowing blood to flow past the vascular implant.
