1. An implantable device comprising:
- a first ring having a first ring radial strength;
a second ring having a second ring radial strength; and
an interconnection coupling the first ring and the second ring, the interconnection covering at least a portion of the implantable device;
wherein the first ring is adjacent to the second ring, the adjacent first and second rings having the same diameter and the first ring radial strength being less than the second ring radial strength, such that the first ring is configured to nest with the second ring.
