  • Patent number: 11877942
    Abstract: An endoprosthesis constraining sleeve includes a single sheet of material forming at least two folds, and a common bond line constraining the single sheet of material to maintain the at least two folds and to form at least two discrete lumens. A first lumen of the at least two lumens is configured to receive a constrained endoprosthesis therein. A second lumen of the at least two lumens is configured to receive a control feature therethrough.

  • Publication number: 20220313418
    Abstract: An endoprosthesis delivery system includes a branched endoprosthesis having a long leg and a short leg, each leg having an end, the short leg including a tail that extends beyond the end of the short leg, a constraint attached to at least a portion of the long leg prior to deployment. The constraint also retains at least a portion of the tail. The constraint is configured to release both the long leg and the tail when the branched endoprosthesis is fully deployed.
