  • Patent number: 12226326
    Abstract: Devices, systems, and methods are provided to maintain or enhance blood flow through the blood vessel. Balloon-expandable, bioresorbable, vascular stent elements configured to be implanted in the blood vessel are described herein. Stent elements comprise a closed cell pattern configured to provide their greatest radial strength at or near the diameters of their intended therapeutic use.
    Type: Grant

  • Patent number: 11491034
    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. Individual stent elements shorten upon expansion creating a space between stent elements. The distance between stent elements when deployed 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.
