Systems and methods are disclosed in which changes in the position and/or orientation of an anatomical structure or of a surgical tool can be measured quantitatively during surgery. In some embodiments, a surgical electronic module can be configured to attach to a surgical device, to continually detect changes in a position and/or orientation of the surgical device during surgery, and to communicate the changes to a user. In this way, where the surgical device is attached to a portion of a patient's anatomy and/or is used to manipulate the patient's anatomy, the surgical electronic module can detect changes in the position and/or orientation of said anatomy. In embodiments where more than one module is used during surgery, the modules can continually detect changes in their positions and/or orientations relative to one another, which correspond to changes in relative positions and/or orientations of the surgical devices to which the modules are attached.

Described herein are methods and apparatuses for the application of electric energy treatment(s) to skin tissue to alter pigmentation, and in particular to remove a tattoo. These methods and apparatuses may deliver pulsed electrical energy having a pulse duration in submicrosecond pulse range to provide high-field strength pulses that may effectively release tattoo ink and allow removal of tattoo ink regardless of ink color or composition.

Provided herein are systems and methods for performing localization within a patient. A method of localization within a body comprises providing at least one processor coupled to at least one data storage device, establishing and calibrating a localization coordinate system within a body by executing a first localization mode by the at least one processor, recalibrating the localization coordinate system by executing a second localization mode by the at least one processor, and localizing a device within the localization coordinate system using the first localization mode and the second localization mode, by the at least one processor. The first localization mode can be an impedance-based localization mode and the second localization mode can be magnetic-based localization mode, or vice versa.

A method for removing tissues may comprise disposing a tissue resection device at a target tissue site, causing the tissue resection device to resect a core of tissue from the target tissue site, removing the core of tissue from the body, wherein the removing the core of tissue from the body creates a core cavity at the target tissue site. A tracking apparatus may be configured to determine a position of a portion of the tissue resection device in three dimensional space.

Novel tools and techniques are provided for implementing intelligent assistance (“IA”) ecosystem. In various embodiments, a computing system might receive device data associated with a device(s) configured to perform a task(s), might receive sensor data associated with sensors configured to monitor at least one of biometric, biological, genetic, cellular, or procedure-related data of a subject, and might receive imaging data associated with an imaging device(s) configured to generate images of a portion(s) of the subject. The computing system might analyze the received device data, sensor data, and imaging data (collectively “received data”), might map two or more of the received data to a 3D or 4D representation of the portion(s) of the subject based on the analysis, might generate and present (using a user experience (“UX”) device) one or more extended reality (“XR”) images or experiences based on the mapping.

Provided herein are systems for modeling a patients cardiac electrical activity data, including at least one diagnostic catheter for insertion into the heart of the patient and a processing unit. The at least one diagnostic catheter includes at least one recording element to record patient data over multiple cardiac cycles. The patient data includes biopotential data and localization data of the at least one recording element. The processing unit includes a clustering routine that: receives the recorded patient data; segments the recorded patient data by cardiac cycle to produce segmented patient data; groups the segments based on one or more characteristics of the segments to produce segmented data groups; and combines the segmented patient data within each segmented data group to produce one or more composite recordings. The systems create one or more models of cardiac electrical activity of the patient based on the one or more composite recordings.

A computer-implemented method of determining locations of transducers on a subject's body for applying tumor treating fields, the method including: selecting a plurality of pairs of locations on the subject's body, each pair of locations having a first location to locate a first transducer and a second location to locate a second transducer; obtaining, for each pair of locations, a voltage measurement and a current measurement for an electric field induced between the first transducer and the second transducer, the induced electric field passing through a tumor of the subject's body; calculating, for each pair of locations, a resistivity based on the voltage measurement and the current measurement; and selecting and outputting one or more recommended pairs of locations based on the calculated resistivities.

In one embodiment, a catheter alignment system includes a catheter to be inserted into a body part, and including catheter electrodes to contact tissue at respective locations within the body part, a display, and processing circuitry to receive signals provided by the catheter, assess respective levels of contact of ones of the catheter electrodes with the tissue of the body part responsively to the received signals, find a direction in which the catheter should be moved to improve at least one of the respective levels of contact of at least one of the catheter electrodes responsively to the respective levels of contact of the ones of the catheter electrodes, and render to the display a representation of the catheter responsively to the received signals, and a direction indicator indicating the direction in which the catheter should be moved responsively to the found direction.

There is provided a method of displaying a pre-acquired three dimensional (3D) image of at least a portion of an organ of a patient, the method comprising: receiving a plurality of electrical readings, each from a different electrode mounted on a catheter inside the portion of the organ of the patient, wherein the electrodes are mounted on the catheter at known distances from each other, transforming the plurality of electrical readings to a corresponding plurality of image points using a mapping transformation that transforms each electrical reading of the catheter from inside the portion of the organ of the patient to an anatomically corresponding image point in the 3D image based on the known distances, and displaying the 3D image with a marking of at least one of the plurality of image points.

The present disclosure provides systems, apparatuses and methods that provide probe-cavity location and motion data based on probe location and respiration data.
