Abstract:
1. A polymer stent configured for being expanded by a balloon, comprising: a plurality of rings composed of ring struts connected at connection regions, wherein all of the ring struts extend only in the circumferential direction, both before and after being expanded by the balloon; and linking struts connecting adjacent rings at the connection regions; wherein, for each of the rings, there is at least one deformable strut among the ring struts; and a notched portion is formed in the at least one deformable strut to induce necking in the deformable strut, the notched portion is spaced apart from the connection regions, whereupon radial expansion of the stent the necking occurring at the notched portion enables the respective ring to increase in diameter and provide radial support for a bodily lumen.
