  • Patent number: 10470767
    Abstract: An end effector includes first and second jaws, first and second buttresses, and an ultrasonic blade. The first jaw includes a fastener cartridge having a first tissue contacting surface and a plurality of fasteners arranged in rows parallel to a longitudinal axis of the first jaw. The first buttress is attached to the first tissue contacting surface and the second buttress is attached to a second tissue contracting surface of the second jaw. The first and second jaws are movable relative to one another and are configured to grasp tissue therebetween. The ultrasonic is activatable to weld the first buttress to the second buttress and to subsequently cut the welded first and second buttresses and tissue grasped between the first and second jaws.

  • Patent number: 10420661
    Abstract: A method of deploying a stent includes receiving a delivery system loaded with a stent and securing the stent in a compressed arrangement by a stent holding assembly including first and second holders having a first protective cover disposed at one end for enclosing a first fastening assembly and a second protective cover disposed at one end of the second holder for enclosing a second fastening assembly, respectively, the stent coupled to the first and second holders members by the first and second fastening assemblies, respectively. The method further includes delivering the stent in an axially expanded and a radially compressed arrangement to an implantation site, retracting the first and second protective covers to expose the first and second fastening assemblies, and actuating the first and second fastening assemblies such that the stent radially expands to engage an inner wall of a lumen.
