  • Patent number: 11903834
    Abstract: According to one embodiment, a heart anchor tensioning device includes a main body and an elongate shaft. A tension member or tether may be inserted through a lumen of the elongate shaft to allow the shaft to be advanced over the tension member and within a body while the main body is positioned outside of the body. The device also includes an anchor coupling mechanism that is configured to engage a heart anchor and move the heart anchor into engagement with a first wall of the heart. The anchor coupling mechanism is able to lock the heart anchor to inhibit proximal movement of the heart anchor along the tension member. The device further includes a tension indicating mechanism that provides an indication of a force being applied to the heart anchor by the device.

  • Publication number: 20230277178
    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.

  • Patent number: 11540825
    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.

  • Publication number: 20220079640
    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.

  • 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: 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.
