The present invention is directed to stent that has a plurality of axially spaced serpentine bands. Each serpentine band comprises a plurality of struts, wherein adjacent struts are connected to each other forming a plurality of peaks and valleys. The plurality of struts comprise a plurality of adjacent pairs of struts, wherein each adjacent pair of struts comprises a first strut and a second strut and wherein the first and second struts have a first end, a second end and a length and a plurality of interconnecting struts axially connect the serpentine bands. The stent further includes a plurality of connector nodes, wherein a plurality of first and second struts that are associated with a connector node have a greater stiffness than a plurality of struts that are not associated with a connector node.

Stent design with struts of various angles and stiffness

Stents having a plurality of serpentine bands including a proximal end portion, a distal end portion, and a middle portion therebetween are herein disclosed. Each of the bands includes peaks and valleys. Serpentine bands of the proximal end portion are connected together in a repeating pattern of connected and unconnected peaks and valleys. Serpentine bands of the distal end portion are connected together in a repeating pattern of connected and unconnected peaks and valleys. The repeating pattern of the proximal end portion is different than the repeating pattern of the distal end portion.
