  • Publication number: 20240130778
    Abstract: A surgical end effector includes an ultrasonic blade and a jaw member. The blade is adapted to receive ultrasonic and electrosurgical energy and defines a distal face. The jaw member is movable relative to the blade from a spaced-apart to an approximated position for clamping tissue and includes a structural body having a body portion and a distal cap portion. The distal cap portion defines an electrode that receives electrosurgical energy. The jaw member further includes a jaw liner engaged within the body portion and extending therefrom towards the blade such that, in the approximated position, the jaw liner contacts the blade to define a gap distance between the electrode and the distal face to facilitate bipolar electrosurgical tissue treatment upon conduction of bipolar energy between the electrode and the distal face and through tissue in contact therewith.

  • Patent number: 5428135
    Abstract: A method for refolding recombinant platelet-derived growth factor from a high expression host cell system, such as E. coli, is provided in accordance with the present invention. The recombinant platelet-derived growth factor is isolated from inclusion body proteins, after which the free sulfydryl groups of the reduced monomeric recombinant protein are blocked. The blocked recombinant protein can then be brought into a biologically active conformation, without interference from the formation of incorrect disulfide bonds. Once in a biologically active conformation, the recombinant platelet-derived growth factor may be unblocked to allow the desired disulfide bonds to form, thus locking the recombinant protein into a biologically active conformation. The present invention also provides a novel mixed disulfide intermediate wherein the free sulfhydryl groups of reduced recombinant platelet-derived growth factor are derivatized to a disulfide blocking agent.

  • Patent number: 5216812
    Abstract: A knife utensil for separating shell members of a mollusk comprised of a bar member having a blade portion mounted to retaining members forming a handle and formed with an arcuate upper honed edge and a concave-shaped lower honed edge defining a point at a free end disposed between a centerline of a bar member and a point at which the upper surface meets the retaining members.
