Abstract: Described herein are percutaneous treatment tools and methods for applying electric treatment to a target tissue, hi some examples the treatment tools described herein allow for adjusting the spacing between the proximal electrode(s) and the distal electrode of the treatment tools. The treatment tools described herein may also be configured to reduce peak electric field for a given potential and/or to increase hoop stress on the tissue upon insertion of the tip to prevent or reduce arcing between the electrodes.

Abstract: A scissor style vessel sealer having a first shaft interconnected to a first jaw by a pivot plate that pivotally couples the first shaft to the first jaw by the pivot and also by a spring that is secured at one end to the first shaft and an opposing end to the pivot plate at a location offset from the pivot and a second shaft connected to a second jaw and pivotally coupled to the first jaw by the pivot. The first shaft and the second shaft are then pivotable from a jaws open position to a jaw closed position. Any further application of force results in the first shaft pivoting relative to the first jaw so that the additional force is not transmitted to the jaws. The first shaft pivoting relative to the first jaw may actuate a button associated with the second shaft.

Abstract: Disclosed is a modular surgical instrument, comprising a handle assembly comprising a handle assembly control circuit and a modular attachment. The modular attachment comprises a nozzle, and a shaft extending distally from the nozzle, the shaft defining a central longitudinal axis. The modular attachment further comprises an end effector distal to the shaft, the end effector comprising a sensor array. The modular attachment further comprises a modular attachment control circuit communicably coupled to the sensor array, and physically coupled to the shaft. The modular attachment control circuit is configured to rotate with the shaft relative to the handle assembly about the central longitudinal axis. The modular attachment control circuit is configured for wireless communication with the handle assembly control circuit.

Abstract: A surgical device, is disclosed herein. The surgical device can include an end effector including a clamp jaw, a trigger configured to open and close the clamp jaw, a sensor configured to detect a relative position of the trigger, and a control circuit communicably coupled to the sensor and a generator, wherein the control circuit is configured to cause the generator to administer energy associated with a surgical operation to be performed on the tissue, receive a signal from the sensor, determine that the clamp jaws are not positioned to administer the energy associated with the surgical operation, and cause the generator to administer energy configured to release the tissue from an ultrasonic blade, wherein the energy configured to release the tissue from the clamp jaw is different than the energy associated with a surgical operation to be performed on the tissue.

Abstract: At least some embodiments of the present disclosure are directed to systems and methods for estimating locations of electrodes and/or electrode assembly of an electroporation ablation catheter when the catheter is deployed. In some examples, the electrode position is estimated using electrical signals collected when a current is injected via tracking electrodes. In certain examples, the electrode positions are updated using one or more geometric models associated with the electroporation ablation catheter.
