Abstract
System including a delivery catheter and a stent disposed at a distal end of the delivery catheter. The stent includes a plurality of radially expandable rings disposed adjacent to one another to define a tubular member having a proximal end portion, and a distal end portion, and a middle portion, each of the radially expandable rings including a plurality of strut members. The middle portion of the tubular member include a plurality of interconnection members extending between longitudinally adjacent expandable rings, the number of the plurality of the interconnection members being greater than that of the end portion of the tubular member. The stent also includes a transition section between the end portion and the middle portion, the transition section including at least one open cell and at least one closed cell. The stent can be self-expandable or balloon expandable.
