1. A stent of generally cylindrical shape and having a longitudinal axis comprised of a plurality of regularly arranged interconnected curvilinear bodies of same shape providing individual closed expansion cells, the cells having relatively wide end portions joined by a relatively narrow center portion and being arranged end to end, longitudinally in longitudinal rows with respect to the longitudinal axis of the stent, the cells being interconnected only by connection members.

7. A stent of generally cylindrical shape comprising:
-
a plurality of curvilinear bodies providing closed expansion cells, the cells being formed of relatively wide end portions and relatively narrow center portions and being arranged end to end, longitudinally in longitudinal rows with respect to the longitudinal axis of the stent; paired longitudinal connecting members connecting the ends of adjacent cells, and circumferentially extending members extending between cells of adjacent rows and interconnecting the cells at the narrow portions. - View Dependent Claims (8)

9. A stent of generally cylindrical shape and having a longitudinal axis and a circumference, comprised of a plurality of regularly arranged interconnected curvilinear bodies of same shape providing individual closed expansion cells, the cells having relatively wide end portions joined by a relatively narrow center portion some of which are arranged end to end, longitudinally in longitudinal rows with respect to the longitudinal axis of the stent, and some of which are arranged circumferentially in circumferential rows with respect to the circumference of the stent.

10. A stent of generally cylindrical shape and having a longitudinal axis comprised of a plurality of bands which are made up of a plurality of regularly arranged interconnected curvilinear bodies of same shape providing closed expansion cells, the cells having relatively wide end portions joined by a relatively narrow center portion and being arranged end to end, longitudinally in longitudinal rows with respect to the longitudinal axis of the stent, the bands being interconnected by the curvilinear bodies shared between certain expansion cells located on adjacent edges of the bands, the certain cells being less than the number of cells which make up the band edges.
