Patent number: 9814518Abstract: Bipolar electrosurgical instrument having a first and a second opposing jaw member at a distal end thereof, wherein each jaw member includes an outer housing, and an inner tissue engaging surface corresponding to the inner tissue engaging surface of the opposing jaw. The instruments includes the ability to move the jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue. The jaws include asymmetrical electrodes disposed on the inner tissue engaging surfaces. A first contact region of the electrode has a greater surface area than that of the second contact region. During resection procedures wider electrodes impart improved sealing energy to the patient-side vessel while providing sufficient energy to resected tissue to effect hemostasis.Type: GrantFiled: November 21, 2016Date of Patent: November 14, 2017Assignee: COVIDIEN LPInventors: Gary M. Couture, Rebecca Coulson

Patent number: 8968316Abstract: A forceps includes an end effector assembly and one or more cutting blades. The end effector assembly defines a longitudinal axis and has a pair of jaw members selectively positionable relative to one another about a pivot. One or more of the jaw members includes an electrically conductive tissue engaging surface adapted to connect to an electrosurgical energy source. One or more of the jaw members includes two or more blade channels defined therein and extending therealong. The one or more cutting blades are selectively movable within one or more of the two or more blade channels.Type: GrantFiled: February 18, 2011Date of Patent: March 3, 2015Assignee: Covidien LPInventors: Jeffrey M. Roy, Rebecca Coulson

Patent number: 8685016Abstract: An electrosurgical system is disclosed. The electrosurgical system includes an electrosurgical generator adapted to supply electrosurgical energy to tissue. The electrosurgical generator includes impedance sensing circuitry which measures impedance of tissue, a processor configured to determine whether a tissue reaction has occurred as a function of a minimum impedance value and a predetermined rise in impedance, wherein tissue reaction corresponds to a boiling point of tissue fluid, and an electrosurgical instrument including at least one active electrode adapted to apply electrosurgical energy to tissue. A tissue cooling period is provided to enhance operative outcomes.Type: GrantFiled: February 23, 2009Date of Patent: April 1, 2014Assignee: Covidien AGInventors: Roberth H. Wham, Rebecca Coulson, Kari L. Riegner, David A. Schechter, Nicole McKenna, Barbara R. Bastian, Jennifer S. Harper

Patent number: 8663222Abstract: An end effector assembly includes opposed jaws moveable from an open to a closed position for grasping tissue therebetween. Each jaw includes an electrically conductive surface adapted to conduct electrosurgical energy through tissue disposed between the jaws. A static bipolar cutting portion including at least one electrically conductive cutting element and at least one insulating element having a first configuration is disposed on at least one of the jaws. The static cutting portion is configured to electrically cut tissue disposed between the jaws upon activation of the cutting element and at least one of an opposing sealing surface and an opposing cutting element. A dynamic cutting portion including at least one electrically conductive cutting element and at least one insulating element having a second configuration is disposed on at least one of the jaws. The dynamic cutting portion electrically transects tissue during movement relative to tissue.Type: GrantFiled: September 7, 2010Date of Patent: March 4, 2014Assignee: Covidien LPInventors: Sara E. Anderson, William H. Nau, Jr., Gary M. Couture, Rebecca Coulson
