An annuloplasty ring to resize a dilated aortic root during valve sparing surgery includes a scalloped space frame having three trough sections connected to define three crest sections. The annuloplasty ring is mounted outside the aortic root, and extends in height between a base plane and a spaced apart commissure plane of the aortic root. At least two adjacent trough sections are coupled by an annulus-restraining member or tether that limits the maximum deflection of the base of the annuloplasty ring. In use, the tether is preferably located in proximity to the base plane of the aortic root. The annuloplasty ring is movable between a first, substantially conical configuration occurring during a diastolic phase of the cardiac cycle, and a second, substantially cylindrical configuration occurring during a systolic phase of the cardiac cycle. The attachment of the annuloplasty ring in proximity to the cardiac valve annulus allows the ring to regulate the dimensions of a dynamic aortic root during the different phases of the cardiac cycle.

An improved closed-cell foam sheet stock and method for producing constant force characteristics in elastomer cushions. A closed cell foam is formed as a corrugated cardboard with regular cavities and support elements between two surface sheets. The resulting stock material possesses similar flexibility to foam stock but with an elongated force curve. A method for modifying this or other corrugated elastomers for efficient constant force curves is further provided where alternating support members are conjoined or buttressed to fold in controlled sigmoid shape under load. The resulting collapsible truss or space frame structure produces a cushion with improved cushioning, load distribution, shock absorption and resistance from lateral collapse while folding uniformly and efficiently to a smooth, compact and comfortable support under full compression. The orthopedic constant force profile allows uses in shoes, furniture, mattresses, sports padding, aircraft seats or packaging applications and extends the dynamic range of more resilient elastic, plastic or foam materials including very lightweight closed cell foam. For packaging applications both the collapsing truss or the less sophisticated corrugated profiles provide lighter weight and improved impact absorption over solid closed-cell foams.
