  • Patent number: 10512462
    Abstract: A surgical stapler has a body, a shaft assembly extending distally from the body, and an end effector coupled with a distal end of the shaft assembly. The end effector has a stapling head assembly, an anvil, and a vacuum port. The vacuum port is operable to draw tissue between the stapling head assembly and the anvil. The anvil is operable to move toward and away from the stapling head assembly to thereby capture the tissue drawn between the stapling head assembly and the anvil. The stapling head assembly comprises a plurality of wheel assemblies and staple cartridges. At least one wheel assembly is operable to rotate to thereby move the anvil toward and away from the body. The remaining wheel assemblies are operable to rotate to thereby drive staples through the captured tissue. The body includes user input features operable to drive the wheel assemblies.

  • Publication number: 20190343526
    Abstract: A surgical staple driver configured for use with a surgical staple cartridge that operably interfaces with a surgical instrument camming member that is axially movable along a first cam axis. A driver body is slidably supportable within the surgical staple cartridge. A camming surface is provided on the driver body that is oriented for camming engagement with the camming member along the first cam axis. The driver further includes a staple supporting portion that is configured to operably support at least one surgical staple thereon relative to the camming surface such that when the camming member engages the camming surface, the camming member passes transversely under a portion of a staple crown of at least one surgical staple supported on the staple supporting portion.

  • Publication number: 20190239876
    Abstract: Devices and methods are provided for forming and securing a tissue plication. More particularly, the devices and methods of the present invention can be used to create multiple tissue folds on an anterior and posterior wall of a stomach cavity to reduce the volume thereof. In one aspect, a method of gastric volume reduction is disclosed that includes advancing a tissue acquisition and fixation device endoscopically into a stomach, manipulating the device to form a first fold of tissue on an interior surface of an anterior wall of the stomach, and manipulating the device to form a second fold of tissue on an interior surface of a posterior wall of the stomach, where the second fold is not attached to the first fold.

  • Publication number: 20190133655
    Abstract: A tissue fixation system is provided for dynamic and rigid fixation of tissue. A fastener connected with an elongate fastening member, such as a cable, wire, suture, rod, or tube, is moved through a passage between opposite sides of tissue. The fastener is provided with a groove that accommodates at least a portion of the fastening member to reduce the profile during the movement through the passage. The fastener is then pivoted to change its orientation. A second fastener can then be connected with the fastening member. While tension is maintained in the fastening member, the fasteners are secured against relative movement. This may be done by deforming the fastening member, either the first or second fasteners, or a bushing placed against the second fastener.

  • Publication number: 20180368826
    Abstract: The present invention provides a surgical system for securing a suture against relative movement with respect to a body tissue. The surgical system includes a fastener and medical device for positioning and securing a fastener onto a suture. The fastener includes inner and outer members that can slide together and rotate. The suture extends through the inner and outer members so that rotation of the inner member causes it to wrap the suture around it. As the suture is wound around the inner member, the fastener is drawn toward a position against the body tissue. Further rotation of the inner member allows tension to be applied to the suture. The fastener may be bonded to the suture in order to further secure the suture against relative movement with respect to the body tissue.

  • Patent number: 10111674
    Abstract: The invention relates to a method of creating a curvilinear cavity within a vertebral body or other body structure. The invention also relates to devices that may be used to perform the steps to create the curvilinear cavity. One such device is a curved drill including a lever and cam sub assembly. The curved drill can include a spring assembly that controls the curvature of the drill. The lever and cam sub assembly can be provided to allow tension to be reduced in the spring assembly.

  • Patent number: 9713468
    Abstract: A method of deploying a surgical fastener into a patient by introducing the fastener into a body of a patient while the fastener is in a first shape having a first loop with a back span and an original size and shape. The method then involves moving end segments of the fastener away from each other substantially along an entire length thereof while keeping the back span in substantially its original size and shape. The method then involves forming the fastener into a second loop having a width greater than a width of the first loop.

  • Patent number: 9713471
    Abstract: A surgical fastener applier having a handle and a fastener housing extending from the handle. The housing contains at least one anvil movable within the staple housing, the anvil has a proximal position and a distal position. When in the distal position a distal end of the anvil extends distal to the distal end of the staple housing. The housing contains a plurality of surgical fasteners each of which in the shape of a loop. At least one of the fasteners is placed around a portion of the anvil when in the distal position. The applier has a first mechanism for moving the anvil distally after a fastener has been deployed, and a second mechanism for moving the anvil distally after a fastener has been deployed. The second means is independent of the first means.
