Abstract

A multi-element, vascular stent may be used to maintain or enhance patency of a blood vessel. The stent may be used in peripheral blood vessels, which may be long and / or tortuous. By using multiple, separate stent elements that are balloon expandable, the multi-element stent may be stronger than a traditional self-expanding stent but may also be more flexible, due to its multiple-element configuration, than a traditional balloon-expandable stent. The distance between stent elements may be based on characteristics of the stent and the target vessel location such that the stent elements do not touch one another during skeletal movement. Thus, the multi-element, vascular stent described herein may be particularly advantageous for treating long lesions in tortuous peripheral blood vessels.

Description

technical field [0001] The present application relates generally to the field of medical devices. More specifically, the application relates to the design and manufacture of endovascular stents intended for maintaining patency (blood flow) of blood vessels (arteries and veins). Background technique [0002] Atherosclerotic cardiovascular disease is the leading cause of death and disability worldwide, accounting for nearly one-third of human mortality. Atherosclerosis is the pathological process of arterial aging; over time, once soft and flexible arteries become stiff and brittle, and then become clogged with the formation of fatty, cholesterol plaques. When cholesterol plaques grow large enough to reduce blood flow and reduce oxygen supply to vital organs, cholesterol plaques can cause chest pain (angina), gangrene (critical limb ischemia), and transient ischemic attacks (mini-strokes ) clinical symptoms. Unstable plaques, riddled with complex calcifications and blood cl...
