The present invention is directed to a flexible expandable stent for implantation in a body lumen, such as a coronary artery. The stent generally includes a series of metallic cylindrical rings longitudinally aligned on a common axis of the stent and interconnected by a series of links which be polymeric or metallic. Varying configurations and patterns of the links and rings provides longitudinal and flexural flexibility to the stent while maintaining sufficient column strength to space the cylindrical rings along the longitudinal axis and providing a low crimp profile, enhanced stent security and radial stiffness.

Flexible stent

A stent retention mold includes two half-molds, each half-mold including a stent supporting surface, and a plurality of protrusions disposed on at least one of the stent supporting surfaces. A stent retention method includes retaining a stent to a balloon using a split mold that includes a stent supporting surface having a plurality of protrusions, so that a portion of the balloon extends through a gap of the stent into a space between two protrusions.
