  • Patent number: 7367976
    Abstract: An endoscopic forceps for treating tissue includes a housing having a shaft affixed thereto which has first and second jaw members attached to a distal end thereof. The forceps also includes an actuator for moving 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 therebetween. Each of the jaw members is connected to a source of electrosurgical energy such that the jaw members are selectively capable of operating in a bipolar mode which enables the jaw members to conduct bipolar energy through tissue held therebetween to treat tissue. The forceps also includes a monopolar element housed within the first jaw member which is selectively movable from a first position within the first jaw member to a second position distal to the first jaw member.

  • Patent number: 7364577
    Abstract: A method for electrosurgically sealing a tissue includes steps of: (A) applying a first pulse of RF energy to the tissue; and (B) applying at least one subsequent RF energy pulse to the tissue and keeping constant or varying RF energy parameters of individual pulses of subsequent RF energy pulses in accordance with at least one characteristic of an electrical transient that occurs during the individual RF energy pulses. The method terminates the generation of the at least one subsequent RF pulse upon a determination that the electrical transient is absent.

  • Publication number: 20080084911
    Abstract: A thermometry assembly includes a thermometer and a mount for mounting the thermometer on a wall or other support structure. The thermometry assembly has an anti-theft system for deterring theft of the thermometer. The anti-theft system generally includes a counter that counts the number of uses of the thermometer during a period beginning from the time the thermometer was last on the mount. A microcontroller of the thermometer is programmed to disable further operation of the thermometer when a threshold number has been reached or exceeded by the counter. The counter is reset when the thermometer is returned to the mount. The anti-theft system includes a solid-state sensor that is activated by a magnet in the mount. The sensor signals to the microcontroller to reset the counter when it is activated by the magnet.

  • Patent number: 7329256
    Abstract: A bipolar electrosurgical instrument for clamping, grasping, manipulating, and sealing tissue includes first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof. The handle being operable to effect movement of 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 therebetween. The bipolar instrument is connectable to a source of electrical energy having a first electrical potential connected to one of the jaw members and a second electrical potential connected to the other of the jaw members such that the jaw members are capable of selectively conducting energy through tissue held therebetween to effect a seal. Both the first and second electrical potentials are transmitted to the jaw members through the first shaft.

  • Patent number: 7311706
    Abstract: A method of manufacturing a seal in an electrosurgical device includes placing components of the electrosurgical device within an elongated housing section, the housing section including an actuator opening, introducing the housing section within a mold filled with a liquid thermoplastic elastomer and allowing the elastomer to flow within the housing, forming an elastomeric inwardly-extending lip portion circumferentially surrounding an opening at a distal end of the electrosurgical device for introducing an electrode therein, and allowing the molded elastomer to cure and become integral with the housing to seal the components within the molded elastomer contained within the housing section. The method may also include the step of forming an elastomeric actuator seal around the actuator opening.
