Abstract: A surgical system includes an end effector assembly having first and second jaw members configured to grasp tissue between tissue contacting surfaces thereof. An electromagnetic induction coil is fixedly disposed within the second jaw member. A thermal cutting element is disposed at least partially within the electromagnetic induction coil and movable relative to the electromagnetic induction coil and the second jaw member between a retracted position, wherein the thermal cutting element is flush with or recessed within the second jaw member, and an extended position, wherein the thermal cutting element protrudes from the second jaw member. The thermal cutting element is formed at least partially from an electromagnetic material capable of being inductively heated. The electromagnetic induction coil is adapted to connect to a source of energy to produce an electromagnetic field within the electromagnetic induction coil to thereby inductively heat the thermal cutting element.

Abstract: A surgical end effector assembly includes first and second jaw members configured to grasp tissue. At least one of the jaw members defines a channel. A cutting element reciprocates through the channel to cut grasped tissue. The cutting element may include a first bevel defined along a first portion of a distal edge on a first side surface of the cutting element and a second bevel defined along a second portion of the distal edge on a second side surface of the cutting element. The first and second portions of the distal edge are sharpened to facilitate cutting tissue upon distal advancement of the cutting element. Alternatively or additionally, the cutting element may include a proximal body and a distal fin defining a height greater than a height of the proximal body and including a thinned portion defining a depression within a first side surface thereof.

Abstract: A system of medical devices includes a radiofrequency generator, a stylet, and an introducer. The stylet includes an elongate shaft having a shaft proximal portion and a shaft distal portion defining a shaft distal end. The shaft is rigid. A radiofrequency puncture electrode is at the shaft distal end. The radiofrequency puncture electrode is electrically connectable to the radiofrequency generator. The introducer includes an elongate tube extending between a tube proximal portion and a tube distal portion defining a tube distal end. The shaft is receivable in the tube with the electrode proud of the tube distal end.

Abstract: An electronic system for multimodal diagnostic measurements and therapeutic interventions includes a plurality of element network layers vertically stacked one with another on a flexible substrate, each element network layer being bi-axially stretchable and comprising a plurality of elements configured in an addressable, interconnected array formed in a multilayered structure and operably performing a distinct function. The electronic system is a multimodal, multiplexed soft electronic system in a multilayered configuration that supports capabilities ranging from high-density spatiotemporal mapping of temperature, pressure and electrophysiological parameters, to options in programmable high-density actuation of thermal inputs and/or electrical stimulation, drug elution, radio frequency ablation, and/or irreversible electroporation ablation.

Abstract: A surgical robotic system includes a first mobile cart, a control tower coupled to the first mobile cart, and a surgical console coupled to the control tower. The first mobile cart includes a surgical robotic arm and an image capture device actuatable in response to a user input and configured to capture a video of an object in a surgical site. The control tower includes a first controller configured to receive the captured video, determine a speed of the object within the captured video, determine a movement speed of the image capture device, and calculate a distance of the object from the image capture device based on the speed of the object and the movement speed of the image capture device. The surgical console includes a display configured to display the captured video of the surgical site and a user input device configured to generate the user input.
