Patent number: 10660724Abstract: A jaw assembly including first and second jaw members configured to clamp tissue therebetween. The first jaw member includes a surface opposing a surface of the second jaw member, a light source, and a light detector. The light source is configured to emit light from an opening defined in the surface of the first jaw member. The light detector is disposed within the opening and is configured to sense properties of light reflected off tissue clamped between the first and second jaw members and to generate signals indicative of the sensed properties of light. A processor is operatively associated with the light detector and is configured to receive the signals from the light detector. The processor is also configured to analyze the signals to determine an attribute of tissue clamped between the first and second jaw members and to provide feedback to a user of the attribute of the tissue.Type: GrantFiled: December 6, 2016Date of Patent: May 26, 2020Assignee: COVIDIEN LPInventors: Elizabeth Hufnagel, Xingrui Chen, Matthew Chowaniec, Peter T. Collings, Paul D. Richard, Michael A. Zemlok

Patent number: 10463382Abstract: An electromechanical surgical system is provided and includes a hand-held surgical device. The surgical device includes a device housing defining a connecting portion for selectively connecting with an adapter assembly, the housing being configured to removably receive a battery therein; at least one drive motor supported in the device housing for controlling power delivered from a battery to the motor. The system includes a battery configured for disposition in the device housing, the battery being capable of powering the at least one drive motor, the battery including at least one display. The device housing is configured such that the at least one display of the battery is visible therethrough.Type: GrantFiled: February 9, 2017Date of Patent: November 5, 2019Assignee: Covidien LPInventors: Michael D. Ingmanson, Kelly Valentine, Elizabeth Hufnagel
