Abstract: According to one embodiment, a guidance system is described for assisting in an advancement of a medical component within a body of a patient. The guidance system features a probe and a console. The console is communicatively coupled to the probe and features AI-based visualization controls and AI-based guidance assistance logic. The AI-based visualization controls are configured to generate, position, and reposition a visualization area between the medical component and a targeted vasculature of the patient. The visualization area is a sub-region of a total imaging area rendered by the console. The AI-based guidance assistance logic is configured to monitor for a presence of the medical component within the visualization area, provide a feedback for generating a notification that the medical component is within the visualization area, and apply an imaging enhancement to at least a portion of imaged data within the visualization area to assist in the advancement.

Abstract: A system, apparatus and method directed to placing a medical instrument in a vasculature of a patient body, the system including an optical fiber with one or more core fibers. The system can include a console having non-transitory computer-readable medium storing logic that, when executed, causes operations of providing an incident light signal to the optical fiber, receiving a reflected light signal of the incident light, wherein the reflected light signal is reflected from at least one of red blood cells or tissue within the patient body, processing the reflected light signal to determine an oxygen level within the patient body near a distal tip of the optical fiber. The method can include determining a location of the distal tip of the optical fiber within the patient body at least based on the oxygen level.

Abstract: Disclosed herein are medical systems, devices, and methods for identifying a blood vessel as a vein or as an artery. The system includes an optical fiber configured for insertion into a blood vessel coupled with a console having a light source, an optical receiver, processors, and logic stored in memory. The optical fiber includes sensors disposed along its length configured to determine a state or condition of the optical fiber, where the state or condition includes a strain, movement, pressure, or temperature. The logic analyzes reflected optical signals emanating from the sensors to determine that the optical fiber is inserted within an artery or within a vein. Logic may also determine a red-blue shift of a projected light to determine a blood flow direction with respect to the optical fiber.

In one embodiment, the placement system comprises a console including a processor and a plurality of optical fiber-based strain sensors included with the catheter. A light source is also included and configured to operably connect with the strain sensors and produce outgoing optical signals incident on the strain sensors. A photodetector is included and configured to operably connect with the strain sensors and receive return optical signals from the strain sensors. A processor is configured to process data from the return optical signals. The data relates to an aspect of the catheter. A user interface such as a display is configured to communicate information relating to the aspect of the catheter.

Abstract: Blood vessel recognition and needle guidance systems, components, and methods thereof are disclosed. A console can be configured to instantiate a target recognition process for recognizing an anatomical target, such as a blood vessel, of a patient and a needle guidance process for guiding insertion of a needle into the anatomical target using ultrasound-imaging data received by the console. The system can perform target identification based on artificial intelligence (AI), which can be trained to recognize targets based on the ultrasound image. The ultrasound probe can be configured to provide to the console electrical signals corresponding to the ultrasound-imaging data. The ultrasound probe can include an array of transducers and, optionally, an array of magnetic sensors respectively configured to convert reflected ultrasound signals from the patient and magnetic signals from the needle, when magnetized, into the electrical signals.

Abstract: A vasculature assessment device includes an imaging probe configured to acquire raw image data of a blood vessel of a patient and a device module having a console coupled with the imaging probe. Logic stored in memory device module determines blood vessel data from the raw image data and applies a trained machine learning model to the blood vessel data to determine suggested catheter parameters for catheter to be inserted within the blood vessel. A vasculature assessment system includes a plurality of the vasculature assessment devices and a computing system coupled with the vasculature assessment devices. Machine learning logic of the computing system performs a machine learning algorithm on historical catheter placement data sets to define the trained machine learning model.

Abstract: Shape-sensing systems and methods for medical devices. The shape-sensing system can include a medical device, an optical interrogator, a console, and a display screen. The medical device can include an integrated optical-fiber stylet having fiber Bragg grating (“FBG”) sensors along at least a distal-end portion thereof. The optical interrogator can be configured to send input optical signals into the optical-fiber stylet and receive FBG sensor-reflected optical signals therefrom. 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 stylet as a tip of the medical device is advanced into a superior vena cava of a patient.
