Abstract:
1. A method of making a stent comprising: providing a seamless tubular workpiece; creating a plurality of stenting turns in the workpiece, the stenting turns defining a lumen centered on a longitudinal axis; and forming a plurality of connector struts connecting adjacent stenting turns, at least one of the connector struts having a transverse cross-section including a luminal apex at the intersection of a first straight line and a second straight line, the luminal apex being the point on the connector strut closest to the longitudinal axis, and an abluminal apex at the intersection of a third straight line and a fourth straight line, the abluminal apex being the point on the connector strut furthest from the longitudinal axis, each of the first, second, third, and fourth straight lines lying in a plane that does not intersect the longitudinal axis, the first, second, third, and fourth straight lines together defining an entire outer perimeter of the transverse cross-section, wherein the forming step comprises forming the at least one connector strut such that the transverse cross-section is symmetrical about a plane that extends through the luminal apex, the abluminal apex, and the longitudinal axis.
