Abstract
The invention includes systems and methods for providing stents having expandable cylindrical elements that are connected by articulated arms and connecting rods. These stents are understood to reduce the shortening that can occur as the stent is expanded from a first radial dimension to a second radial dimension.
Claims10
An intraluminal stent for implanting in a body lumen, comprising:
- a first cylindrical element adapted for expanding from a first radial dimension to a second radial dimension;
- a second cylindrical element adapted for expanding from a first radial dimension to a second radial dimension, and being positioned adjacent and spaced away from the first cylindrical element to define a longitudinal axis extending through the first and second cylindrical elements;
- an articulated arm connecting the first and second cylindrical elements;
- and
- a substantially straight connecting rod connecting the first and second cylindrical elements,
- wherein said first cylindrical element comprises a coil having a plurality of peaks and troughs and the articulated arm joins the first and second cylindrical elements at a point on the coil of said first cylindrical element at a location between a peak and a trough,
- whereby a force acting radially outward may expand the stent from the first radial dimension to the second radial dimension.
