Segmented balloon-expandable stent system for preservation of the arterial lumen during bending

Abstract

Devices, systems, and methods are provided to maintain or enhance blood flow through the blood vessel. Balloon-expandable, bioresorbable, vascular stent elements that provides high radial force at the arterial wall while still preserving patency of the lumen during bending are described herein. Multiple, short, balloon-expandable scaffolds mounted in series on a delivery system and deployed simultaneously via a single balloon inflation are described. The individual scaffolds maintain the arterial lumen with high radial force while the inter-scaffold spaces are free to bend and compress during limb movement. The result is an artery in which the lumen is both adequately preserved and effectively stented.
