Patent number: 11291443Abstract: A surgical apparatus has a clamp and a stapling mechanism. The clamp has a first jaw and a second jaw to clamp on a body tissue at a desired location for a stapling operation. The stapling mechanism is controlled by a trigger handle or a switch assembly. The surgical apparatus has a controller for providing a delay between clamping and actuating of the firing mechanism of the stapling mechanism. The delay provides for a desired amount of time for tissue compression producing a more uniform staple formation. The surgical apparatus also has an indicator. The indicator provides feedback about the status of the stapling mechanism and also displays a time of tissue compression by the clamp.Type: GrantFiled: May 14, 2019Date of Patent: April 5, 2022Assignee: Covidien LPInventors: Frank J. Viola, Gregg Krehel, Guido Pedros, Michael A. Soltz, Robert DeSantis, Henry E. Holsten, Russell Heinrich, Michael Ingmanson, Philip Irka, David M. McCuen, Gene A. Stellon

Patent number: 10828065Abstract: A surgical access system includes a cannula assembly and an obturator assembly. The obturator assembly provides an insufflation channel or fluid passage for delivery of insufflation fluids directly to an underlying cavity, e.g., the abdominal cavity. The fluid passage is completely confined within the obturator assembly isolated from the cannula assembly and terminates at a location distal of the cannula assembly such that the insufflation fluids released from the fluid passage are directed toward the abdominal cavity and not within the cannula assembly.Type: GrantFiled: July 24, 2018Date of Patent: November 10, 2020Assignee: COVIDIEN LPInventor: Henry E.
