Publication number: 20240108399Abstract: An apparatus including a body, a shaft assembly extending distally from the body, and an end effector configured to grasp and transmit RF energy to the tissue. The end effector includes a first jaw having a first tissue grasping feature and a second jaw. The second jaw is pivotably coupled to the first jaw between an open position, a partially closed position, and a closed position. The second jaw includes a proximal taper having a proximal electrode surface, a distal taper including a distal electrode surface, and a juncture between the proximal and distal electrode surface. The juncture is spaced further from the first tissue grasping feature compared to the proximal and distal end while the second jaw is in the partially closed position. The proximal and distal electrode surface deform to define a gap with the first tissue grasping feature while in the closed position.Type: ApplicationFiled: December 14, 2023Publication date: April 4, 2024Inventors: James M. Wilson, Randolph C. Stewart, Jason R. Lesko, Gregory A. Trees, Kristen L. D'Uva

Publication number: 20230225754Abstract: A surgical apparatus includes a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and a rigidizing member. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide includes a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section includes a first member and a second member. The second member is longitudinally translatable relative to the first member. The end effector includes an ultrasonic blade in acoustic communication with the waveguide. The rigidizing member is configured to selectively engage at least a portion of the articulation section to thereby selectively provide rigidity to the articulation section.Type: ApplicationFiled: February 17, 2023Publication date: July 20, 2023Inventors: William B. Weisenburgh, II, Barry C. Worrell, Jeffrey D. Messerly, Kristen L. D'Uva, Craig N. Faller, John B. Schulte, Kristen G. Denzinger, Joseph E. Hollo, Jason R. Sullivan, Brian D. Black, Frederick L.

Publication number: 20230112022Abstract: An apparatus comprises a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide comprises a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section comprises a plurality of body portions aligned along the longitudinal axis and a flexible locking member. The flexible locking member is operable to secure the body portions in relation to each other and in relation to the shaft. The end effector comprises an ultrasonic blade in acoustic communication with the waveguide. The articulation drive assembly is operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis.Type: ApplicationFiled: October 12, 2022Publication date: April 13, 2023Inventors: Barry C. Worrell, Benjamin J. Danziger, Benjamin D. Dickerson, Brian D. Black, Cara L. Shapiro, Charles J. Scheib, Craig N. Faller, Daniel J. Mumaw, David J. Cagle, David T. Martin, David A. Monroe, Disha V.

Publication number: 20220395317Abstract: An apparatus includes a shaft assembly and an end effector. The shaft assembly includes an outer sheath, at least one irrigation conduit, and at least one suction conduit. The end effector includes a first electrode, a second electrode, and a web. The electrodes extend distally relative to a distal end of the outer sheath. The electrodes are operable to apply bipolar RF energy to tissue. The web extends laterally between the first and second electrodes. The web is positioned distal to the distal end of the outer sheath.Type: ApplicationFiled: June 23, 2022Publication date: December 15, 2022Inventors: Mark A. Davison, Mark E. Tebbe, Kristen G. Denzinger, Ryan M. Asher, Craig T. Davis, Kevin Bash, Eric Roberson, John E. Brady, Jeffrey A. Bullock, Jeffrey L. Aldridge, Monica L. Zeckel, Shan Wan, Kristen L. D'Uva
