1. A method of fabricating an articulated support structure, comprising:
- placing a plurality of pins through openings in an alignment plate;
placing a plurality of eyelets onto the plurality of pins;
layering a plurality of strut members each having a plurality of orifices onto the plurality of pins by placing the pins through the orifices;
connecting the plurality of strut members into a chain having a first end and a second end by swaging the eyelets; and
wrapping the chain into a tubular structure by connecting the first and second ends of the chain.

Abstract
A support structure includes strut members interconnected by articulated joints to form a series of linked scissor mechanisms. The structure can be remotely actuated to compress or expand its shape by adjusting the scissor joints within a range of motion. In particular, the support structure can be repositioned within the body lumen or retrieved from the lumen. The support structure can be employed to introduce and support a prosthetic valve within a body lumen.

17. A method of fabricating an articulated support structure, comprising:
-
interlinking a plurality of strut members into a flattened chain having a first end and a second end, wherein each of the plurality of strut members comprises a plurality of orifices, comprising; placing a plurality of alignment guides through at least one orifice of each of the plurality of strut members, wherein each of the plurality of alignment guides is placed through the orifices of at least two strut members; securing the at least two strut members together; removing the plurality of alignment guides from the orifice; and connecting the first end of the flattened chain to the second end of the flattened chain to form a tubular structure. - View Dependent Claims (18, 19, 20, 21)
