Abstract: An instrument includes a hand piece, a pair of jaws, and an actuator. The jaws extend from the hand piece. Each jaw includes a proximal portion and a distal portion. The actuator is in communication with both the hand piece and the pair of jaws. Movement of the actuator causes the jaws to move from an open configuration to a closed configuration. During the move from the open configuration to the closed configuration, the jaws undergo a translational movement followed by a first non-translational movement.

Abstract: A medical instrument that includes a needle and an expandable member located at a distal end of the needle. The expandable member includes a blocking member. The expandable member is configured to move tissue away from a distal end of the needle and/or from a distal end of a tubular member that is in fluid communication with a substance source. A substance is configured to be expelled into the anatomy through the expandable member. The blocking member is configured to restrict or prevent the substance from being expelled through the portion of the expandable member that includes the blocking member.

Abstract: An instrument including a first arm, a second arm, and a blade. The first arm includes a lumen in communication with a source of irrigation fluid and one or more outlets in communication with the lumen for delivering the irrigation fluid to a surgical site. The instrument is switchable between a first configuration and a second configuration. In the first configuration, the instrument is configured to deliver a first therapy current through a distal end of the first arm, a distal end of the second arm, or both. In the second configuration, a distal end of the blade extends beyond the distal end of the first arm and beyond the distal end of the second arm.

Abstract: A jaw assembly that includes a first jaw and a second jaw. The first jaw includes a first outer jaw member having an effecting surface; a first inner jaw member having an effecting surface; and an element connecting the first outer jaw member and the first inner jaw member. The first inner jaw member is moveable relative to the first outer jaw member. The effecting surface of the first outer jaw member is proud of the effecting surface of the first inner jaw member in a direction of the second jaw.

Abstract: Apparatus and associated methods relate to controlling electrical power of an electrotherapeutic signal that is provided to a biological tissue engaged by an electrosurgical instrument during a medical procedure. Electrical power—a product of a voltage difference across and an electrical current conducted by the engaged biological tissue—is controlled according to a therapeutic schedule. The electrotherapeutic schedule can be reduced or terminated in response to a termination criterion being met. In some examples, the termination criterion is a current characteristic, such as, for example, a decrease in current conducted by the engaged biological tissue. In some examples, the termination criterion is a biological tissue resistance characteristic, such as, for example, an increase in the biological tissue resistance that exceeds a predetermined delta resistance value.
