    摘要: An end effector assembly for use with an instrument for sealing vessels and cutting vessels includes a pair of opposing first and second jaw members which are movable relative to one another from a first spaced apart position to a second position for grasping tissue therebetween. Each jaw member includes an electrically conductive tissue contacting surface connected to an electrosurgical energy source. At least one of the jaw members includes an electrically conductive cutting element disposed within an insulator defined in the jaw member. At least one channel is included in the insulator which is configured to deliver fluid between the jaw members.

    摘要: A directional flow valve in a cardiovascular prosthesis test system includes a regurgitant flow passage. Forward flow from a pump through the valve is unrestricted and allowed to pass freely through the directional flow valve. Regurgitant flow is allowed across the directional flow valve to reduce a negative pressure gradient across the prosthetic device. The volume of regurgitant flow is controllable by changing a size of the regurgitant flow pathway.

    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.
