摘要

A collapsible-expandable tubular stent (29) constructed of shape-memory material which is implantable into a human heart, which comprises proximal and distal rings (71,73) and at least two spaced apart posts (69) that extend axially between said rings (71, 73), said distal ring (73) comprising a plurality of distal arms (77) which are connected to the distal ring (73) at only one end and which have a free opposite end; said proximal ring (71) comprising a plurality of, which are connected at only one end to the proximal ring (71) and which have a free opposite end, which proximal arms (75) are constructed to swing radially outward at their free ends.
