Systems and methods for analyzing complexity of surgical footage are disclosed. A system may include at least one processor configured to analyze frames of the surgical footage to identify an anatomical structure in a first set of frames. The processor may access first historical data based on an analysis of first frame data captured from a first group of surgical procedures and analyze the first set of frames to determine a first complexity level. The processor may analyze the surgical footage to identify in a second set of frames a medical tool, an anatomical structure, and an interaction between the medical tool and the anatomical structure. The processor may access second historical data based on an analysis of a second frame data captured from a second group of surgical procedures and analyze the second set of frames to determine a second complexity level associated with the second set of frames.

Systems and methods for predicting post-discharge risk are disclosed. A system may include at least one processor configured to access frames of video captured during a specific surgical procedure on a patient and access stored historical data identifying intraoperative events and associated outcomes. The processor may analyze the accessed frames and, based on information obtained from the historical data, identify in the accessed frames at least one specific intraoperative event. The processor may further determine, based on information obtained from the historical data and the identified at least one intraoperative event, a predicted outcome associated with the specific surgical procedure, and output the predicted outcome in a manner associating the predicted outcome with the patient.

Aspects of the disclosure relate to an adjustable implant configured to be implanted into a patient that includes an adjustable portion moveable relative to a housing. The adjustable implant may include various smart components for enhancing operation of the implant. Smart components may include a controller for managing operations and a transducer for communicating ultrasound data with an external interface device. Additional smart components may include a load cell within the housing for measuring an imparted load; a sensor for measuring angular position of the adjustable portion; a dual sensor arrangement for measuring imparted forces; a reed switch; a half piezo transducer; and an energy harvester.

An ultrasonic transducer for an ultrasonic surgical instrument includes a proximal hub, a piezoelectric rod array including a plurality of piezoelectric rods spaced-apart from one another and disposed in parallel and longitudinally-extending orientation relative to one another, and a distal horn including a distal connector configured to engage a waveguide. The proximal hub and the distal horn are configured to engage one another to retain the piezoelectric rod array therebetween under compression.

Disclosed herein are left atrial appendage (LAA) occluders that include self-powered physiological sensors to monitor physiological parameters of a subject. The sensors can be powered by harvesting energy generated by the patient's body or using wireless power delivery technologies. The disclosed devices can be used to close the LAA and to provide self-powering sensors to wirelessly monitor physiological parameters such as heart rate, pressure, temperature, size of the atrium, and levels of biomarkers such as C-reactive protein (CRP) and B-type natriuretic peptide (BNP) (e.g., using biosensors). In addition to addressing the stroke risk for patients with non-valvular atrial fibrillation, the disclosed devices offer post-surgical connected care that can reduce hospital readmissions, provide superior medical management, and improve patient quality of life.

A treatment method and a treatment system capable of effectively irradiating an antibody-photosensitive substance bound to a tumor cell with a near-infrared ray. The treatment method includes: intravenously administering the antibody-photosensitive substance; inserting a guide wire and a catheter into a main artery of an organ having the tumor cell; removing the guide wire; inserting an optical fiber into the catheter and advancing the optical fiber to a target position while checking a position of the optical fiber with an orientation marker disposed on the optical fiber; and irradiating the antibody-photosensitive substance bound to a tumor cell membrane with the near-infrared ray from the optical fiber while reducing an influence of blood in the artery on the near-infrared ray after 12 hours to 36 hours from intravenous administration.

A tactile sensor, a surgical instrument, and a method of making the tactile sensor are provided. In one embodiment, a tactile sensor includes a first electrode, a second electrode, and an intermediate layer between the first electrode and the second electrode. The intermediate layer includes a polyurethane-zinc oxide nanocomposite. Further, one or both of the first and second electrodes may include a silver conductive paste.

A handheld instrument for endoscope surgery includes a shaft, a jaw, a handle, a phased array ultrasonic sensor, and a signal wiring. The jaw is placed at one end of the shaft and has a holding function. The handle is placed at the other end of the shaft and includes an operation mechanism for operating the jaw. The phased array ultrasonic sensor is mounted on the jaw and has an imaging function. The signal wiring is provided to the shaft and connects the ultrasonic sensor and the handle.

An ablation catheter including an elongate shaft, an inflatable balloon positioned at a distal region of the elongate shaft, a first ablation electrode disposed outside of and carried by an outer surface of the inflatable balloon, a first ultrasound transducer disposed outside of the inflatable balloon, and a flexible circuit. The flexible circuit includes a first conductor and a second conductor and is disposed outside of and carried by the outer surface of the inflatable balloon. The first conductor is in electrical communication with the first ablation electrode, and the second conductor in electrical communication with the first ultrasound transducer.

A lithotripter is provided that includes a lithotripsy apparatus for treatment of a urinary tract stone by fragmentation. The lithotripsy apparatus includes a lithotripsy wave guide shaft configured to transmit an energy form to at least one urinary tract stone. The lithotripter includes a sensing device configured to provide signal data for determining optimal application of energy during treatment with the lithotripsy apparatus. The lithotripter includes a processor configured to collect the signal data and provide feedback to a user. The processor has a control logic configured to determine at least one of: a) if the lithotripsy wave guide shaft is in contact with a tissue; b) if the lithotripsy wave guide shaft is in contact with a stone; c) type of stone; d) if a user is applying force in excess of a predetermined threshold; and e) physical characteristics of a stone. A method is also provided.
