Abstract: A surgical device to deliver energy to tissue can include a hand piece and a shaft. The hand piece can be operable to control the surgical device. The shaft can extend along a longitudinal axis and the shaft can include a proximal portion and a distal portion opposite the proximal portion. The proximal portion can be connected to the hand piece. The device can include an end effector connected to the distal portion of the shaft. The end effector can include an active electrode, an insulator at least partially surrounding the active electrode, and a return electrode adjacent the insulator. The device can include a heat pipe connected to the return electrode and extending at least partially through the shaft. The heat pipe can be configured to transfer heat from the return electrode to the hand piece.

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.

Abstract: A method of treating diverticulitis while maintaining the bioactivity of the diverticulum. The devices and methods include placing an endoscopic device within a colonic lumen relative to at least one diverticulum and inserting a plurality of particles into the at least one diverticulum. The plurality of particles can include magnetic particles, non-magnetic particles, or both. The plurality of particles can partially or totally occlude the diverticulum preventing unwanted material from entering the diverticulum. Additionally, the plurality of particles can include antimicrobial and therapeutic layers that can treat diverticulitis and prevent or minimize diverticulitis from occurring.

Abstract: Disclosed embodiments include apparatuses, systems, and methods for positioning electrodes within a body. In an illustrative embodiment, an apparatus for slidably moving multiple features relative to a sheath inserted into a body and positioned relative to a reference point includes a primary actuator configured to move a primary electrode, a secondary actuator configured to move a secondary electrode, and a control mechanism. The control mechanism is configured to selectively prevent movement of at least one of the primary actuator based on a position of the secondary actuator and of the secondary actuator based on a position of the primary actuator and lock positions of the primary actuator and the secondary actuator.

Abstract: Techniques for detecting depth contours of an anatomical target and for enhancing imaging of the anatomical target are provided. In an example, a reference pattern of light can be projected across an anatomical target and an image of the reflected light pattern upon the anatomical target can be captured. The captured light pattern can be analyzed to determine contour information, which can then be used to provide 3D cues to enhance a 2-dimensional image of the anatomical target.

Abstract: A method of treating a calculi mass can include using an ultrasonic probe to produce acoustic energy and fragment the mass. The method can include varying the frequency at which fragmentation occurs to treat the mass with a resonant frequency. The ultrasonic probe can have a distal tip for contact with the mass, where the tip has a morphology for concentrating stress on the mass. The ultrasonic probe can have two or more ultrasonic horns to allow for higher voltage and power levels.
