Various aspects of the present disclosure are directed towards apparatuses, systems, and methods for electroporation ablation. The electroporation ablation catheter may include an electrode assembly comprising one or more electrodes configured to generate electric fields in target tissue in response to a plurality of electrical pulse sequences delivered in a plurality of therapy sections, and an ultrasound transducer configured to generate a first set of ultrasound signals during a first electrical pulse sequence of the plurality of electrical pulse sequences and generate a second set of ultrasound signals after an end of the first electrical pulse sequence and before a beginning of a second electrical pulse sequence, the second electrical pulse sequence being an electrical pulse sequence subsequent to the first electrical pulse sequence.

A system for deploying needles in tissue includes a controller and a visual display. A treatment probe has both a needle and tines deployable from the needle which may be advanced into the tissue. The treatment probe also has adjustable stops which control the deployed positions of both the needle and the tines. The adjustable stops are coupled to the controller so that the virtual treatment and safety boundaries resulting from the treatment can be presented on the visual display prior to actual deployment of the system.

A balloon is provided for selectively moving an esophagus away from an ablation site. The balloon is received through an oral cavity and into the esophagus of a patient. A deflecting member is provided in the tube, the balloon, or both, so as to selectively distort to bend the balloon and/or the tube to move the esophagus away from the ablation site. The deflecting member may comprise at least one of a strip made of a shape memory material that is responsive to the receipt of a stimulus to deflect to a predetermined shape, a strip that is made of or contains a ferrous material and that deflects in response to the presence of a magnetic field, and a selectively tensionable cable, wire, or string. The deflecting member may be supplemented by a stiffening strip that is located in the balloon and that causes the balloon to expand circumferentially and asymmetrically when inflated.

A side-firing laser system with a standoff catheter includes an optical fiber configured to emit therapeutic laser radiation in a direction generally transverse to an axis of the fiber; and a catheter through which the optical fiber is inserted during a surgical procedure. The catheter includes a transparent end section through which the therapeutic laser radiation passes to vaporize tissue outside the catheter, an open distal end to permit exit of irrigation fluid from the catheter, and an opening in a side of the end section, the opening having dimensions that are approximately equal to or less than cross-sectional dimensions of the therapeutic laser radiation. When the fiber is moved to a position at which the therapeutic laser radiation passes through the opening, the laser radiation causes coagulation or vaporization of tissues.

Medical or surgical devices, instruments, systems, and methods for use in optically sensing loads acting on a patient's anatomy may include a surgical device or instrument configured for insertion to a surgical site and an interrogator coupled to the surgical device or instrument via an optical fiber having a sensing area at a location of the surgical device or instrument at which a load is to be sensed. The measured load may be used as being indicative of a load acting on a patient's anatomy. Such measured or determined load may be used to make decisions before, during, or after a patient procedure.

A system that compensates for movement during a surgical procedure on a patient includes a lidar array and a processor. The surgical procedure operates according to a surgical plan. The lidar array tracks the movement of the patient, a medical instrument, and/or a medical professional during the procedure. The processor modifies the surgical plan to compensate for one or more of the movements.

Devices, systems, and methods for a robot-assisted surgery. Navigable instrumentation, which are capable of being navigated by a surgeon using the surgical robot system, and navigation software allow for the navigated placement of interbody fusion devices or other surgical devices. The interbody implant navigation may involve navigation of access instruments (e.g., dilators, retractors, ports), disc preparation instruments, trials, and inserters.

A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to treat tissue to create lesions without ablating the tissue. The system includes a first treatment device having a plurality of electrodes. The electrodes are maintained in axial alignment and fixed radial spacing in retracted and extended positions. The device includes a basket having a plurality of arms. The arms are maintained in a fixed radial spacing in the collapsed position of the basket.

A system includes a connector with a central lumen. A multi-lumen chamber is removably connected to and in fluid communication with a proximal end of the central lumen. The multi-lumen chamber includes a first lumen aligned and adjacent a second lumen. The first lumen includes a first fluid in a proximal portion of the first lumen and a hydrophilic polymer in a distal portion of the first lumen, a first plunger rod within the first lumen to control flow of the first fluid into the distal portion to mix with the hydrophilic polymer in a first state to form a first mixture, and a first port. The second lumen includes a second fluid, a second plunger rod within the second lumen to distally move the second fluid and the first mixture in a second state, and a second port.

A severed nerve may be surgically rejoined and severed axons fused via sequential administrations of solutions. The solutions may include a priming solution comprising methylene blue in a Ca.sup.2+-free saline solution, a fusion solution comprising about 50% (w/w) PEG, and a sealing solution comprising Ca.sup.2+-containing saline. The PEG fusion solution may be applied in a nerve treatment device configured to isolate the injured segment of the nerve. The device may include a containment chamber for creating a fluid containment field around the anastomosis. The device may have slits, slots, and/or apertures in opposing endwalls of the device designed to receive the nerve. The device may have an open bath configuration or may include separable lower and upper bodies to create a closed bath configuration. The device may include one or more fluid ports in fluid communication with the containment chamber for introducing and/or removing fluid.
