1. An intraluminal stent, comprising:
- a plurality of planar rings aligned along a common longitudinal axis and contained within a first end section, a middle section, and a second end section;
wherein each ring is defined by a circumference entirely contained within a plane;
wherein only the first end section includes at least one ring having the inclined circumferential plane and the remaining circumferential planes are perpendicular to the common longitudinal axis; and
a plurality interconnecting members having a length extending parallel to the common longitudinal axis and joining adjacent rings.

Abstract
A stent for implantation in a body lumen for protecting from rupture a fibrous cap in order to treat vulnerable plaque. One embodiment of the stent includes inclined planar rings joined by interconnecting links. The planar rings are inclined relative to a plane perpendicular to a longitudinal axis extending the length of the stent. The inclined planar rings provide vessel support yet require lower balloon pressures to deploy and exert lower radial stresses so that when appositioned with vulnerable plaque are less likely to rupture the fibrous cap.
