Patent number: 11166760Abstract: A medical instrument is provided and includes a housing and a shaft coupled to the housing. The shaft has a proximal end and a distal end. An end-effector assembly is disposed at the distal end of the shaft. The end-effector assembly includes first and second jaw members. At least one of the first and second jaw members is movable from a first position wherein the first and second jaw members are disposed in spaced relation relative to one another to at least a second position closer to one another wherein the first and second jaw members cooperate to grasp tissue therebetween. The medical instrument also includes one or more light-emitting elements and one or more light-detecting elements configured to generate one or more signals indicative of tissue florescence. The one or more light-emitting elements are adapted to deliver light energy to tissue grasped between the first and second jaw members.Type: GrantFiled: July 24, 2020Date of Patent: November 9, 2021Assignee: Covidien LPInventors: Shobhit Arya, Kristy Lee Cloyd, Vadzim Chalau, Daniel S. Elson, George B. Hanna, Martin A. B. Hedegaard, Molly Stevens, Lei Su

Patent number: 10098690Abstract: A method of sealing bowel tissue includes grasping bowel tissue between first and second electrically-conductive surfaces, applying a clamping pressure to the grasped bowel tissue in a range of about 1 kg/cm2 to about 2.5 kg/cm2, supplying energy to at least one of the first and second electrically-conductive surfaces such that the energy is conducted between the first and second electrically-conductive surfaces and through the grasped bowel tissue to seal the grasped bowel tissue, and monitoring one or more parameters during the supplying of energy to the electrically-conductive surface(s). Instruments, end effector assemblies, generators, and systems suitable for this purpose are also provided.Type: GrantFiled: February 28, 2018Date of Patent: October 16, 2018Assignee: COVIDIEN LPInventors: Shobhit Arya, Lei Su, Ara W.
