    摘要： An electrosurgical system for sealing tissue is disclosed which includes an electrosurgical forceps having a shaft member and a jaw member disposed at a distal end thereof. The jaw members are movable from a first position in spaced relation relative to one another to at least one subsequent position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members including a sealing plate which communicates electrosurgical energy through tissue held therebetween. The jaw members are adapted to connect to an electrosurgical generator. The system also includes one or more sensors which determine a gap distance between the sealing plates of the jaw members and a microprocessor which is adapted to communicate with the sensor and measure an initial gap distance between the sealing plates as well as to generate a desired gap distance trajectory based on the initial gap distance. The microprocessor is further adapted to communicate with the at least one sensor in real time to adjust output level of the electrosurgical generator as a function of the measured gap distance during the sealing process.

    摘要： An electrode sealing assembly is designed for use with an electrosurgical instrument for sealing tissue and includes first and second jaw members each having an insulative housing and being movable from a first position in spaced relation relative to one another to at least one second position for grasping tissue therebetween. Each of the jaw members includes an electrically conductive sealing member disposed within the respective insulative housing. At least one of the insulative housings includes at least one tissue engaging surface configured to extend beyond the electrically conductive sealing member of one of the jaw members. The tissue engaging surface of the insulative housing cooperates with the opposing insulative housing of the opposing jaw member to both pinch and spread tissue when the jaw members are moved to the second position to decrease extraneous energy transmittance to tissue surrounding the jaw members.

    摘要： A fatigue testing system provides simultaneous cycle testing for a plurality of prosthetic devices under simulated physiological loading conditions. A plurality of sample holders containing test samples of prosthetic devices is positioned between a distribution chamber and a return fluid chamber to form an integrated test chamber. A reciprocating linear drive motor operates a rolling bellows diaphragm to cyclically pressurize fluid within the test chamber and drive the pressurized fluid through the prosthetic devices being tested. The test chamber defines a return flow conduit in fluid communication with each of the sample holders, the return fluid chamber, and the distribution chamber. Compliance chambers and throttle valves associated with each of the sample holders regulate the pressure gradient and back pressure across the prosthetic devices being tested.

    摘要： An electrosurgical bipolar forceps for sealing and dividing tissue is disclosed. The forceps includes one or more shaft members having an end effector assembly disposed at a distal end thereof. The end effector assembly includes two jaw members movable from a first position to a second position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members includes an electrically conductive surface adapted to connect to a first energy source which communicates electrosurgical energy through tissue held therebetween. The forceps also include an energy-based cutting element adapted to connect to a second energy source and disposed between the jaw members. The energy-based cutting element is moveable from a first configuration when said jaw members are in the first position to a second configuration wherein the energy-based cutting element is disposed at an angle between the jaw members.
