  • 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.

  • Patent number: 11464660
    Abstract: Various devices, systems, and methods that can be used in the treatment of obesity and related illnesses are disclosed. In some instances, the cecum of an obese patient is distended to a pathophysiological size for a therapeutically effective period. The distention may be achieved by introduction of an object that is of foreign origin relative to the body of the patient into the cecum of the patient. In some instances, the distention is achieved by a medical device that transitions from an undeployed state, in which the medical device is introduced into the cecum of the patient, to an expanded state in which the medical device distends the cecum by an amount sufficient to trigger a colo-gastric brake in the patient.

  • Patent number: 11432841
    Abstract: A tissue removing catheter includes an apposition mechanism that selectively imparts an axially compressive load on the catheter body to bend the catheter and urge a tissue-removing element toward a blood vessel wall. The apposition mechanism can include one or more adjustment lines and an adjustment mechanism for selectively tensioning one of the adjustment lines to impart the compressive load on the catheter body. Two adjustment lines can have diametrically opposed positions and be wound onto a spool of the adjustment mechanism in opposite directions so that rotation of the spool simultaneously shortens one adjustment line and lengthens the other. The catheter body can have a more flexible bending segment adjacent the tissue-removing element to promote bending near the tissue-removing element operative to urge the tissue-removing element in apposition with the blood vessel.

  • Patent number: 11399936
    Abstract: A system and method for restoring (e.g., replacing) a defective heart valve of a patient. A delivery system is manipulated to percutaneously deliver and implant a stented prosthetic heart valve to a native heart valve. A post-dilatation balloon is percutaneously delivered to the implantation site, and a compliant segment thereof is arranged within a region of the implanted prosthesis. The balloon is inflated such that the compliant segment expands and contacts the prosthesis, expanding a remodeling region of the prosthesis to a remodeled state. With these and related techniques, remodeling of an implanted, stented prosthetic heart valve to better match the native valve shape is possible, providing many benefits such as reducing the risk of paravalvular leaks.
