  • Patent number: 11980556
    Abstract: Apparatus and methods are provided for flaring a stent deployed within a branch vessel including an ostium communicating with a main vessel, a first end of the stent extending at least partially from the branch. A catheter is provided that includes a first balloon carried on its distal end, and a second balloon that includes a distal section overlying at least a portion of the first balloon and a proximal section. The catheter distal end is introduced into the main vessel and positioned through the ostium and stent into the branch until the first balloon is disposed within the stent. The first balloon is expanded to anchor the stent, and the second balloon is expanded to flare the first end of the stent. Optionally, the first balloon is expanded further, e.g., to expand the stent within the branch body lumen and/or dilate the lesion.

  • Patent number: 11850386
    Abstract: Inflation devices and methods for using them are provided for selectively inflating and deflating multiple balloons on a catheter. For example, the inflation device may include a first valve including a plurality of first valve ports and a first valve member movable between multiple positions for opening and closing fluid paths between the first valve ports, a second valve including a plurality of second valve ports and a second valve member movable between multiple positions for opening and closing fluid paths between the second valve ports, and an actuator coupled to the first and second valve members for directing the first and second valve members between multiple positions, e.g., to selectively pull vacuum and sequentially inflate the balloons.

  • Patent number: 11510797
    Abstract: Apparatus and methods are provided for flaring a stent deployed within a branch vessel including an ostium communicating with a main vessel, a first end of the stent extending at least partially from the branch. A catheter is provided that includes a balloon having a reinforced region adjacent an unreinforced region. When the balloon is positioned at a desired location, e.g., within a stent, prosthetic valve, or other tubular prosthesis, the balloon may be inflated to a first pressure causing the reinforced and unreinforced regions to expand substantially simultaneously. Upon inflation of the balloon beyond the first pressure, the reinforced region of the balloon remains at the first diameter and the unreinforced region continues to expand, e.g., to flare one or more ends of the prosthesis.
