Publication number: 20180125479Abstract: Methods for repairing a meniscus, and particularly a torn meniscus. A method of repairing a meniscus may include using a suture passer to pass a suturing element from the region between the superior surface of the meniscus and the femoral condyle, through the meniscus tissue, into the region between the inferior surface of the meniscus and the tibial plateau, across the inferior surface of the meniscus, and back to the superior surface of the meniscus, without deeply penetrating the posterior capsular region of the knee. Equivalently, the suture element may be passed from the inferior surface of the meniscus to the superior surface and back to the inferior surface.Type: ApplicationFiled: January 9, 2018Publication date: May 10, 2018Inventors: Justin D. Saliman, Brad S. Culbert, Alexander Jasso, Michael J. Hendricksen, John G. McCutcheon, Christopher P. Bender, Michael Murillo

Publication number: 20180125480Abstract: This instrument is intended to facilitate intra-corporeal laparoscopic tying of knots. The shafts of two small diameter laparoscopic graspers are combined within a common external sheath, and both are joined to a common handle, to be used by one hand. One grasper has no handle, but is able to rotate, and acts as a donor grasper, whilst the other has a regular scissors type of handle, is stationary, and acts as a recipient grasper. The instrument enables the head end of a suture to be passed from a donor grasper to an adjacent recipient grasper, passing behind and around its tail strand, forming the knot, in the same manner as the tying of shoe-laces.Type: ApplicationFiled: January 1, 2018Publication date: May 10, 2018Inventor: Peter Fan

Publication number: 20180125481Abstract: A motor-driven surgical cutting and fastening instrument that comprises an end effector, an electric motor, and a motor control circuit. The motor control circuit is for monitoring a parameter of the electric motor that is indicative of movement of a moveable member of the end effector, and for adjustably controlling the electric motor based on the monitored parameter to thereby adjustably control movement of the moveable member of the end effector during forward rotation of the electric motor.Type: ApplicationFiled: November 7, 2017Publication date: May 10, 2018Inventors: David C. Yates, Frederick E. Shelton, IV, Bret W. Smith, Brett E. Swensgard, Ryan J. Laurent

Publication number: 20180125482Abstract: A device for fixing a first and a second tissue part or a tissue part and an implant part to each other is provided, providing a fastener including a thermoplastic material and a fastening instrument. The fastening instrument includes a first instrument component with a first contact surface facing toward a distal side and a second instrument component has a foot with a second contact surface distally of the first contact surface and facing toward a proximal side. The first instrument component and the second instrument component are displaceable with respect to each other, so that the fastener is compressible between the first and second contact surfaces by application of a relative force between the components. The instrument also includes an energy source for coupling mechanical energy into one of the instrument components to soften and/or melt an end portion of the fastener.Type: ApplicationFiled: January 10, 2018Publication date: May 10, 2018Inventors: Jörg Mayer, Mario Lehmann, Andrea Müller, Andreas Wenger

Publication number: 20180125485Abstract: A surgical stapling device includes a handle assembly, an elongate body extending distally from the handle assembly, and a tool assembly. The tool assembly is mounted onto the distal portion of the elongate body for articulation and includes a staple cartridge that supports a plurality of staples and pushers. An actuation sled is movable through the staple cartridge to eject staples from the staple cartridge and a clamp member is movable through the tool assembly to move the tool assembly from an open position to an approximated position and to advance the actuation sled through the staple cartridge to eject staples and transect tissue. In order to minimize the space for the firing assembly in the proximal portion of the tool assembly, the actuation sled and clamp member are supported in a nested relationship in a pre-actuated state of the tool assembly. The clamp member is subsequently moved to a position proximal of the actuation sled during a firing stroke of the stapling device.Type: ApplicationFiled: November 8, 2016Publication date: May 10, 2018Inventors: John Beardsley, David Nicholas

Publication number: 20180125486Abstract: A circular surgical stapling device includes a reload assembly that is supported on a distal end of an elongate shaft of the stapling device. The reload assembly includes a housing, a pusher assembly movably supported within the housing, a knife carrier movably supported within the pusher assembly, and an annular knife supported on the knife carrier. The elongate body includes a pusher drive member and a knife carrier pusher. The knife carrier includes first engagement structure that is configured to releasably engage second engagement structure formed on the knife carrier pusher to releasably couple the knife carrier pusher to the knife carrier. A reload insert or member is supported on or integrally formed with the housing of the reload assembly. The reload member includes a first portion configured to prevent separation of the first and second engagement structures and a second portion configured to accommodate separation of the first and second engagement structures.Type: ApplicationFiled: November 4, 2016Publication date: May 10, 2018Inventor: Joseph Guerrera

Publication number: 20180125487Abstract: An end effector includes a cartridge assembly having a first tissue contact surface, an anvil assembly having a second tissue contact surface, and one or more tissue pockets defined in one of the first or second tissue contact surfaces. The anvil and the cartridge assemblies are moveable between an open position and a closed position to selectively clamp tissue between the first and second tissue contact surfaces. Each tissue pocket is configured to capture tissue therein while the anvil and the cartridge assemblies are disposed in the closed position. Each tissue pocket is configured to prevent the tissue from migrating away from the first and second tissue contact surfaces while the tissue is clamped between the first and second tissue contact surfaces.Type: ApplicationFiled: November 4, 2016Publication date: May 10, 2018Inventor: John Beardsley
