Abstract: An ultrasound probe includes a light source configured to project a visual indication onto a skin surface of the patient. The visual indication includes different visual characteristics that are based on characteristics of the anatomical target such as a location with respect to the probe and/or an identification of an anatomical target as a vein or as an anatomical element other than a vein, such as an artery. Visual characteristics include shapes, locations, and/or colors of the projected visual indication. Logic of the probe performs location and/or identification processes on ultrasound image data that may include applying trained machine-learning models to the ultrasound image data. Some embodiments, include a virtual/augmented reality headset and/or a needle tracking system. An ultrasound system includes machine-learning logic that generates the trained machine-learning models from historical ultrasound image data sets and actual anatomical target location/identification data sets.

The system can include a reference device including a reference magnet and an ultrasound probe including an ultrasound acoustic transducer or acoustic array that acquires ultrasound images and a magnetometer that detects a magnetic field generated by the reference magnet. The ultrasound probe couples a first ultrasound image with a first magnetic field strength, wherein both of the first ultrasound image is received and the first magnetic field strength is detected at a first time. The system can include a console including a processor and non-transitory computer-readable medium having stored thereon a plurality of processor executed logic modules that perform operations including receiving and recording a plurality of coupling of ultrasound images and detected magnetic field strengths, and generating a 3D visualization from the ultrasound images.

Abstract: A shape-sensing system can include a stylet, an optical interrogator, a console, and a display screen. The stylet can include an optical fiber with fiber Bragg grating (“FBG”) sensors along a length of the optical fiber. The optical interrogator can be configured to send input optical signals into the optical fiber and receive FBG sensor-reflected optical signals from the optical fiber. The console can be configured to convert the reflected optical signals with the aid of filtering algorithms of some optical signal-converter algorithms into plottable data for displaying plots thereof on the display screen. The plots can include a plot of curvature vs. time for each FBG sensor of a selection of the FBG sensors for identifying a distinctive change in strain of the optical fiber as the stylet is advanced into a superior vena cava of a patient.

Abstract: A catheter assembly can include a catheter, a controller, and an internal power source. The catheter can include a catheter tube and a catheter hub, wherein a proximal-end portion of the catheter tube can be disposed in the catheter hub. The catheter tube can incorporate a plurality of piezoelectric transducers into a length of the catheter tube. The plurality of piezoelectric transducers can be configured as a plurality of vibrators for vibrating and, thereby, inhibiting buildup of biomaterial on a luminal or abluminal surface of the catheter tube by way of vibrations along the length of the catheter tube when the catheter tube is placed in a vasculature. The controller can include a processor and memory, wherein the controller can be configured to control at least the plurality of piezoelectric transducers. The internal power source can be configured to power the controller and the plurality of piezoelectric transducers.

Abstract: Systems and methods for extending a guidewire from an insertion tool are disclosed. A guidewire assembly includes a slider configured to engage a guidewire carrier. The guidewire carrier defines a lumen configured to receive a guidewire therein. The guidewire carrier is biased to a non-linear, coiled resting state and can elastically transition to a linear extended state. As the guidewire assembly and slider are urged distally, the slider transitions the guidewire carrier from the non-linear state to the linear extended state. A distance travelled by the slider is less than a distance travelled by a tip of the guidewire as the guidewire carrier transitions from the coiled state to the linear state.

Abstract: Preloaded catheters are manufactured with a stylet, guidewire, or similar medical device disposed within the catheter, extending through a valve of the connector at a proximal end. During storage and transport, the stylet can remain in place for a prolonged period of time, which can cause stretching, indentations, and damage to the valve faces. These indentations can cause the valve leak, resulting in failure of the device as a whole. Embodiments disclosed herein are directed to devices and methods for preventing contact between the medical device and the valve faces, mitigating damage thereto.

Abstract: A medical needle assembly includes a stylet having non-circular cross-sectional shape disposed within the needle lumen. The needle and the stylet each define respective electrodes that enable ascertainment of an electrical property of a body substance adjacent the distal tip of the needle. An electrically insulative coating having a uniform thickness covers the stylet. Wire leads enable connection of the electrodes to a measurement module configured to measure an electrical property of a body substance adjacent a distal end of the needle during insertion. Electrical property measurement enables identification of the location of the needle tip within the patient based on the measurement value. A major diameter of the non-circular cross-sectional shape extends across the needle lumen to create first and second flow paths extending along the lumen on opposite sides of non-circular cross-sectional shape. The first and second flow paths enable blood to flow along the lumen during use.

Abstract: A medical network system is communicatively coupled with a number medical device tracking systems that utilize magnetic systems to track elongate medical devices along anatomical pathways within patients having differing physical attributes, such as height and weight. The medical network system collects tracking records from the medical device tracking systems and applies machine learning and/or artificial intelligence technics to the tracking record data to correlate recorded anatomical pathways with the differing physical attributes. The medical network system receives a patient value set of physical attributes for a specific patient from a medical device tracking system and provides a predicted anatomical pathway based on the correlation and the patient value set. The medical device tracking systems tracts the elongate medical device with respect to the predicted anatomical pathway during placement. The medical device tracking systems may also utilize fiber optic shape sensing systems to track the placement of elongate medical.

Abstract: Disclosed herein are dynamically adjusting ultrasound-imaging systems and methods thereof. For example, an ultrasound-imaging system can include an ultrasound probe, a console, and a display screen. The ultrasound probe includes an array of ultrasonic transducers that, when activated, emit generated ultrasound signals into a patient, receive reflected ultrasound signals from the patient, and convert the reflected ultrasound signals into corresponding electrical signals for processing into ultrasound images. The console is configured to execute instructions for dynamically adjusting a distance of activated ultrasonic transducers from a predefined target or area, an orientation of the activated ultrasonic transducers to the predefined target or area, or both the distance and the orientation of the activated ultrasonic transducers with respect to the predefined target or area. The display screen is configured to display a graphical user interface including the ultrasound images processed by the console from the corresponding electrical signals of the ultrasound signals.
