A plurality of inner bridges can extend between opposing adjacent apices of the distal and proximal inner rings. Each of the plurality of inner bridges can form an eyelet. The implant can include a pair of outer rings comprising a distal outer ring and a proximal outer ring. The distal and proximal outer rings that can each be formed by a plurality of struts connected by apices formed in a zig-zag pattern. A plurality of outer bridge members can include a plurality of outer bridge members that extend between opposing adjacent apices of the distal outer ring and distal inner ring and outer bridge members that extend between opposing adjacent apices of the proximal outer ring and proximal inner ring. ## Claims ### Claim 1 An intravascular implant comprising: a pair of inner rings comprising a distal inner ring and a proximal inner ring, the distal and proximal inner rings each being formed by a plurality of struts connected by apices to form a zig-zag pattern; a plurality of inner bridges that extend between every other opposing adjacent apices of the distal and proximal inner rings; each of the plurality of inner bridges forming an eyelet; a pair of outer rings comprising a distal outer ring and a proximal outer ring; the distal and proximal outer rings each being formed by a plurality of struts connected by apices to form a zig-zag pattern; and a plurality of outer bridge members, the plurality of outer bridge members including outer bridge members that extend between opposing adjacent inward apices of the distal outer ring and outward apices of the distal inner ring and the plurality of outer bridge members including outer bridge members that extend between opposing adjacent inward apices of the proximal outer ring and outward apices of the proximal inner ring;
