  • Patent number: 11564816
    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.

  • 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.

  • Patent number: 11234844
    Abstract: A multi-element, bioresorbable, 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. Thus, the multi-element, bioresorbable, vascular stent described herein may be particularly advantageous for treating long lesions in tortuous peripheral blood vessels.

  • Publication number: 20200390569
    Abstract: A vascular stent may be used to maintain or enhance patency of a blood vessel. 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 stent elements are formed from a bioresorbable polymer material. The radial rigidity of the stent is configured to decrease after implantation in a vessel as the polymer is absorbed. The thickness of the stent, cell shape, polymer material, and/or treatment of the polymer material may be configured to provide a high initial radial rigidity to the vessel upon implantation and a decrease in the radial rigidity of the vessel over time.
