Patent Images
1. A stent for implantation in a body lumen, the stent having an open-ended tubular shape defined by a structure comprising:
- at least one continuous elongated helical band element comprised of substantially uniform shaped and spaced undulating portions forming end loop portions, the helical element extending substantially over the length of the stent body, each of the undulating portions forming a peak and a trough, anda plurality of curvilinear elements extending between and interconnecting the peaks of the adjacent, undulating portions of the helical element over its length.

Abstract
An expandable tubular reinforcing member used for body lumens such as blood vessels, the reinforcing member being formed of a continuous elongated helical element comprised of spaced undulating portions forming end loop portions and including a plurality of curvilinear connector elements extending between and interconnecting at least some of the adjacent undulating portions of the helical element over its length.
