Patent number: 11944299Abstract: A surgical instrument. The surgical instrument has a force delivery system which communicates a changing force to a user of the surgical instrument when a limit of a surgical function is reached. A sensor senses position of a moving element to communicate a signal to the force delivery system. In various embodiments, the system generates a vibratory force to signal the user.Type: GrantFiled: March 3, 2023Date of Patent: April 2, 2024Assignee: Cilag GmbH InternationalInventors: Frederick E. Shelton, IV, Jerome R. Morgan, Richard L. Leimbach, Mark D. Overmyer

Patent number: 11937866Abstract: A method for performing an electrosurgical procedure using an electrosurgical instrument including an end effector is disclosed. The method comprises applying a bipolar energy to a target tissue grasped by the end effector in a tissue-feathering segment, applying an energy blend of the bipolar energy and a monopolar energy to the target tissue in a tissue-warming segment and a tissue-sealing segment following the tissue-warming segment, and discontinuing the bipolar energy but continuing to apply the monopolar energy to the target tissue in a tissue-cutting segment following the tissue-sealing segment.Type: GrantFiled: May 28, 2020Date of Patent: March 26, 2024Assignee: Cilag GmbH InternationalInventors: Frederick E. Shelton, IV, Kevin M. Fiebig, Taylor W. Aronhalt, Jeffrey D. Messerly, Mark S. Zeiner, Sarah A. Worthington, Joshua P. Morgan, Nicholas M. Morgan

Patent number: 11931034Abstract: A surgical instrument includes an anvil and an elongate channel. The elongate channel includes a plurality of first electrical contacts and a plurality of electrical connectors comprising a plurality of second electrical contacts, wherein the electrical connectors are spring-biased such that a gap is maintained between the first electrical contacts and the second electrical contacts. The surgical instrument further includes a staple cartridge releasably attachable to the elongate channel, wherein the staple cartridge has a cartridge body comprising a plurality of staple cavities, a plurality of staples deployable from the staple cavities into the tissue, and a plurality of third electrical contacts, wherein the attachment of the staple cartridge to the elongate channel moves the electrical connectors causing the second electrical contacts to bridge the gap and become electrically coupled to the first electrical contacts.Type: GrantFiled: January 12, 2021Date of Patent: March 19, 2024Assignee: Cilag GmbH InternationalInventors: Sol E. Posada, Mark D. Overmyer, Raymond E. Parfett, Brian D. Schings, Brett E. Swensgard, Richard L. Leimbach, Shane R. Adams, David C. Yates, Jason L. Harris, Frederick E.

Publication number: 20240081802Abstract: Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient's body while maintaining insufflation.Type: ApplicationFiled: November 16, 2023Publication date: March 14, 2024Inventors: Mark S. Ortiz, David T. Martin, Matthew C. Miller, Mark J. Reese, Wells D. Haberstich, Carl Shurtleff, Charles J. Scheib, Frederick E. Shelton, IV, Jerome R. Morgan, Daniel H. Duke, Daniel J.

Patent number: 11918210Abstract: A staple cartridge is disclosed. The staple cartridge can comprise a cartridge body comprising a deck and a bottom surface opposite the deck. The staple cartridge can comprise a plurality of staple cavities, wherein each staple cavity extends into the cartridge body from the deck to the bottom surface. Additionally, a plurality of wells can be defined into the staple cartridge from the deck to a lowermost surface of the well. A plurality of staples can be removably positioned in the staple cavities. The staple cartridge can comprise a tissue thickness compensator releasably secured to the cartridge body, wherein the tissue thickness compensator comprises a compensator body and a plurality of extensions extending from the compensator body into the wells, wherein at least one extension is compressed within one of the wells. Each well can surround at least one staple cavity and/or can extend between at least two staple cavities.Type: GrantFiled: June 13, 2022Date of Patent: March 5, 2024Assignee: Cilag GmbH InternationalInventors: Frederick E. Shelton, IV, Lauren S. Weaner, Jerome R. Morgan, Michael J. Vendely, Taylor W. Aronhalt, Chester O. Baxter, III, Mark S. Zeiner

Patent number: 11918215Abstract: A staple cartridge for use with a surgical instrument that includes a cartridge body, a longitudinal row of first staple cavities, a longitudinal row of second staple cavities, a third staple cavity, a first staple driver and a second staple driver. The cartridge body has a longitudinal slot that defines a longitudinal axis. The first and second longitudinal rows of staple cavities are obliquely-oriented relative to the longitudinal axis and a third staple cavity is positioned substantially parallel to the longitudinal axis. The staple cavities positioned in the first and second rows are configured to receive staples. The first and second staple drivers include staple supports and ramps. The first ramp of the first staple driver is positioned beneath at least one first staple support and the second ramp is laterally offset relative to the second staple support.Type: GrantFiled: September 27, 2021Date of Patent: March 5, 2024Assignee: Cilag GmbH InternationalInventors: Jason L. Harris, Mark S. Zeiner, Janna B. Volz, Nichole Y. Kwee, Frederick E. Shelton, IV

Publication number: 20240072560Abstract: A surgical instrument is configured to compensate for battery pack and drivetrain failures. One method includes generating a firing sequence, determining whether a subset of rechargeable battery cells is damaged during the firing sequence, and stepping-up an output voltage of the battery pack to complete the firing sequence in response to a determination that a subset of the rechargeable battery cells is damaged. Another method includes generating a mechanical output to motivate a drivetrain to transmit a motion to a jaw assembly of the surgical instrument, activating a safe mode in response to an acute failure of the drivetrain, and activating a bailout mode in response to a catastrophic failure of the drivetrain. Another method includes driving a drivetrain, sensing and recording vibration information from the drivetrain, generating an output signal based on the vibration information, and determining a status of the surgical instrument based on the output signal.Type: ApplicationFiled: November 7, 2023Publication date: February 29, 2024Inventors: Frederick E. Shelton, IV, Mark D. Overmyer, David C. Yates, Jason L. Harris

Patent number: 4565258Abstract: The present invention is a stereo headset system for use with a stereo headset device and a stereo sound system. The stereo headset device is of the stethoscope type and has a pair of sound tubular mains. A coupling plug is mechanically and acoustically coupled to the pair of sound tubular mains. The stereo headset system includes an enclosure having a first chamber, a second chamber, a third chamber and a fourth chamber. The first and second chambers are mechanically and acoustically coupled to the coupling plug of the stereo headset device. A first electro-acoustic transducer is disposed in the third chamber of the enclosure and is acoustically coupled to the first chamber of the enclosure. A second electro-acoustic transducer is disposed in the fourth chamber of the enclosure and is acoustically coupled to the second chamber of the enclosure. The third and fourth chambers of the enclosure are water-proofed.Type: GrantFiled: August 7, 1984Date of Patent: January 21, 1986Inventors: Donald F. Butler, Mark E. Shelton
