  • Patent number: 10973666
    Abstract: Flared stents are disclosed, and apparatus and methods for delivering such stents into a bifurcation between a main vessel and a branch vessel. The stent includes a first tubular portion a second flaring portion that may be flared radially outwardly to contact the ostium. The stent may include variable mechanical properties along its length. The stent may be delivered using a catheter including proximal and distal ends, the stent overlying first and second balloons on the distal end. During use, the catheter is advanced through an ostium into the branch to place the stent within the branch. The first balloon is expanded to flare the stent to contact a wall of the ostium, thereby causing the stent to migrate partially into the ostium. The second balloon is expanded to fully expand the stent within the ostium and branch.

  • Patent number: 10966722
    Abstract: Surgical methods involving cutting and sealing tissue include affixing a first adjunct material to tissue at a treatment site, such as by stapling the adjunct to tissue. A second adjunct material is applied to at least a portion of the first adjunct material such that the second adjunct material interacts with the first adjunct material to form a seal in an area of the tissue covered by at least one of the first and the second adjunct material. The resulting tissue sealing structure, which includes a combination of the two adjuncts, is believed to be superior to the sealing properties of either adjunct alone.

  • Patent number: 10959747
    Abstract: Devices, systems, and methods of the present disclosure are directed to efficient and accurate removal of tissue from a three-dimensional anatomic structure, such as a breast, of a patient. For example, a cup can be positioned on the patient's breast to conform the breast (e.g. via suction) to a known three-dimensional contour, and a cutting tip can be moved along the three-dimensional contour at one or more predetermined distances from at least one surface of the cup. The cutting tip can remove tissue along the three-dimensional contour to form a skin envelope. As compared to a manual process performed by a surgeon, formation of the envelope through controlled movement of the cutting tip along the three-dimensional contour can improve control over dimensions of the envelope, thus, facilitating achievement of consistent outcomes by reducing the likelihood of complications associated with an envelope that is too thick, too thin, or uneven.

  • Patent number: 10959737
    Abstract: A reposable surgical clip applier includes a handle assembly, a shaft assembly releasably engagable with the handle assembly, and a clip cartridge assembly releasably engagable within the shaft assembly. The handle assembly includes a proximal drive member and a proximal pusher bar movable through the proximal drive member. When the reposable surgical clip applier is assembled, the proximal drive member of the handle assembly is positioned proximally adjacent an inner drive assembly of the shaft assembly such that movement of handle(s) of the handle assembly towards an approximated position actuates a jaw assembly of the shaft assembly. When the reposable surgical clip applier is assembled, the proximal pusher of the handle assembly is positioned proximally adjacent a distal pusher of the clip cartridge assembly such that movement of the handle(s) towards a spaced-apart position loads a distal-most surgical clip from the clip cartridge assembly into the jaw assembly.

  • Patent number: 10959748
    Abstract: An ultrasonic instrument comprises an ultrasonic transducer, an acoustic waveguide, and an ultrasonic blade. The blade includes a pair of obliquely extending edges. The obliquely extending edges diverge away from the longitudinal axis of the waveguide and away from each other along respective paths extending distally in relation to the waveguide. A distal portion of the blade is wider than a proximal portion of the blade along a plane. The blade further includes a curved distal edge and several laterally presented surfaces. The laterally presented surfaces may provide combinations of concave and convex curvatures. The laterally presented surfaces may be angled and/or curved along one or more orthogonal planes associated with the longitudinal axis of the waveguide.

  • Patent number: 10952735
    Abstract: The adjustable uterine compression apparatus for postpartum hemorrhage includes at least one belt adapted for encircling the uterus transversely, the belt having keeper loops so that the belt can be cinched to continuously adjust the degree of compression applied to the uterine arteries. The belt may also be shortened and used to apply compression to the ovarian arteries. Preferably, a plurality of belts are applied spaced apart axially along the body and cervix of the uterus. The belts may be applied separately and independently, or may be embedded or incorporated into a sheet or vest that may be applied posteriorly behind the uterus and further secured by straps extending over the fundus that are cinched to at least one of the transverse belts to apply axial compression, in addition to transverse compression of the uterus. The belt(s) and vest may be made of polyglactin mesh, so that they are bioabsorbable.
