Abstract:
1. A radially expandable stent comprising: a plurality of strut members; a plurality of side by side helical elements extending helically about an axis of said strut members and interposed between said strut members, said strut members comprising a plurality of strut elements; and a helix angle, said helix angle being an acute angle formed between a plane perpendicular to an axis of said stent and said helical element; said helical elements comprise a plurality of side by side elongated elements along a length of said helical elements, each of said helical elements being connected to each of said strut elements with side by side elongated flexible curved linking elements providing a radially expandable tubular structure, said side by side elongated linking elements are thinner in width than said helical elements; wherein when said stent is radially expanded from a crimped state, a diameter of said stent increases and the helix angle of each of the helical elements in an expanded state decreases from the helix angle in a crimped state.
