Abstract
A stent which minimizes or solves the problem of restenosis. The present stent is designed so as to have a cyclical change in diameter, the change in diameter corresponding to the changes in blood pressure caused by the cardiac cycle. The present stent is constructed through several structural members, each structural member interlocking in a fashion which permits the stent diameter to be altered from a first, diastolic diameter to a second, systolic diameter. This variable diameter is provided through a series of joints between the interlocking structural members. The joints may be provided in any acceptable manner, including an interlocking dog bone configuration, an interlocking elastic coupling, mating struts, as well as interlocking guides.
