Abstract:
1. A coronary stent having a longitudinal axis along the length of the stent comprising: a. a first loop containing section having loops, said first loop containing section having an axis orthogonal to the longitudinal axis of the stent, the loops in said first loop containing section occurring at a first frequency; b. a second loop containing section having loops, said second loop containing section having an axis orthogonal to the longitudinal axis of the stent, the loops in said second loop containing section also occurring at said first frequency; c. said first and second loop containing sections each form a single, continuous, generally sinusoidal pattern around the entire circumference of the stent; and d. a third loop containing section, said third loop containing section formed of a single, continuous, generally sinusoidal pattern also having an axis orthogonal to the longitudinal axis of the stent, the loops in said third loop containing section occurring at a second frequency that is higher than said first frequency, said third loop containing section disposed in the general circumferential space between each of said first and second loop containing sections to form consecutive repeating patterns along the longitudinal axis of the stent for at least two repetitions and alternately joined to said first and second loop containing sections directly at curved portions of said first, second and third loop containing sections forming a uniform pattern of flexible cells; e. the loops in said first, second and third loop containing sections being disposed and adapted to cooperate so that, components of said third loop containing section contribute to the cell's elongating or shortening when the stent is flexed; and f. the loops of the first, second, and third loop containing sections further include struts having a thickness in the radial direction and width in the circumferential direction, wherein the struts of the first and second loop containing sections are wider than the width of the struts of the third loop containing section.
