Patent number: 11389228Abstract: A surgical instrument includes a temperature sensor and a control unit that is operable to deactivate an end effector of the surgical instrument. In some versions the temperature sensor detects the temperature of a transducer, while in others the temperature sensor detects the temperature of the end effector. The surgical instrument may also include a trigger and a trigger position sensor. A force sensor or a position sensor may be included to determine the force and/or position of the transmission assembly. The end effector may also include a force sensor or a micro coil. A surgical instrument having a sensor may be included in a surgical system that includes a control unit and a remote controller. In some instances the remote controller may have one or more force-feedback components. In addition, a device interface and a surgeon interface may be included to remotely adjust the settings of the control unit.Type: GrantFiled: September 5, 2017Date of Patent: July 19, 2022Assignee: Cilag GmbH InternationalInventors: Kevin L.

Patent number: 8727964Abstract: An apparatus for regulating the functioning of a patient's organ or duct includes an elongated member having a first end and a second end. The elongated member has a compressible ventral surface and a substantially rigid dorsal periphery, wherein the elongated member includes a fluid bladder positioned along the ventral surface. A fastener is disposed on the first end of the elongated member. The fastener is configured to engage the second end of the elongated member so that the elongated member forms a loop around the organ or duct. A tension element is disposed for movement within the elongated member. A drive element is associated with and engages the tension element for causing the tension element to control the tension applied by the elongated member against a patient's body organ or duct. Alternate embodiments are also disclosed.Type: GrantFiled: September 18, 2009Date of Patent: May 20, 2014Assignee: Ethicon Endo-Surgery, Inc.Inventors: Daniel F. Dlugos, Jr., Thomas E.
