Patent number: 11160512Abstract: A monitoring system is disclosed for in vivo monitoring of preselected physiological parameters associated with acute and/or chronic tissue compromise or failure in one or multiple tissue/organ sites in real time. In one method, a body portion of a surgical stapling device is positioned adjacent a first tissue section, an anvil assembly adapted to engage the body portion is positioned adjacent a second tissue section, and a monitoring device is positioned adjacent the first and/or second tissue sections. The monitoring device includes a sensor adapted to measure a preselected physiological parameter and a transmitter for transmitting signal to an extracorporeal receiving unit. The surgical stapling device is fired to mechanically secure the first and second tissue sections with at least one staple and the preselected physiological parameter is monitored via the information transmitted from the monitoring device to the receiving unit.Type: GrantFiled: May 12, 2017Date of Patent: November 2, 2021Assignee: COVIDIEN LPInventors: Yong Ma, Nelson Scarborough, Marisha Godek, Rohan Shah, James Power, Nilay Mukherjee, Frank Viola, Edward Mckenna, Shannon Campbell
