1. A stent comprising:
- a main body having a circumference defining a primary lumen and having a longitudinal axis extending therethrough, the main body having a first region and a second region, the first region comprising at least one band disposed circumferentially about the longitudinal axis of the main body,the second region comprising a plurality of interconnected rings concentrically disposed about a side branch opening, the side branch opening being in fluid communication with the primary lumen, an outermost ring occupying a full circumference of the main body, each of the interconnected rings consisting of two longitudinally oriented elements and two circumferentially extending elements, wherein each longitudinally oriented element comprises a repeating waveform defining a straight axis oriented parallel to said longitudinal axis.

Abstract
A stent has a main body, which has a circumference that defines a primary lumen and longitudinal axis, which extends therethrough. A first region of the main body comprises at least one band disposed circumferentially about the longitudinal axis. A second region of the main body comprises a plurality of interconnected rings concentrically disposed about a side branch opening. An outermost ring extends fully about the circumference of the main body. Each of the rings consist of two longitudinally oriented elements and two circumferentially extending elements.

23. A stent comprising:
-
an expandable framework having primary lumen therethrough, the expandable framework defining a longitudinal axis, the expandable framework having a proximal end region, a distal end region and a middle region therebetween, the proximal end region and the distal end region each comprising at least one band coaxial with said longitudinal axis, the middle region comprising a first side branch ring and a second side branch ring, the first side branch ring defining a side branch opening in fluid communication with the primary lumen, the second side branch ring extending concentrically around the first side branch ring, each of said side branch rings consisting of two longitudinally oriented elements and two circumferentially extending elements, each circumferentially extending element comprising a repeating waveform defining an axis oriented in a stent circumferential direction, each longitudinally oriented element comprising a repeating waveform defining a straight axis oriented parallel to said longitudinal axis; wherein the second side branch ring occupies a full circumference of the expandable framework.
