Publication number: 20240245513Abstract: A heart anchor tensioning device includes a main body and an elongated shaft. A tension member or tether through a lumen of the elongated shaft allows the shaft to advance over the tension member and within a body while the main body is positioned outside of the body. The device 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 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.Type: ApplicationFiled: February 16, 2024Publication date: July 25, 2024Inventors: Kevin Van Bladel, Lon Annest, Ernest Heflin, Gilbert Mata, JR., Lawrence Crainich, Brian LaRose

Publication number: 20220079640Abstract: 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.Type: ApplicationFiled: April 26, 2021Publication date: March 17, 2022Inventors: Peter M.

Patent number: 10512462Abstract: 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.Type: GrantFiled: February 7, 2017Date of Patent: December 24, 2019Assignee: Ethicon LLCInventors: Kevin D.
