摘要： Embodiments described herein are directed to an automatic catheter measurement system for determining a length of a catheter required to extend between an insertion site and a target location, prior to placement of the catheter. The system can include a measurement device that can be aligned with, and map, a three-dimensional arrangement of one or more external landmarks. The measurement device can include magnetic and/or fiber optic systems to map the external landmarks. The system then determines a framework to provide a predicted catheter length required to extend between the insertion site and target location. The measurement device can also be included with the catheter during placement to confirm the actual catheter length and improve the accuracy of future predicted frameworks.

摘要： 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.

摘要： Embodiments disclosed herein are directed to steerable devices configured to negotiate tortuous vascular pathways. The system can include a stylet having a shapeable portion formed of a shape-memory, super-elastic material such as Nitinol. The stylet can be placed within a catheter and can include a fiber-optic strain sensor (FOSS) system configured to determine a shape of the stylet. Passing a fluid of a predetermined temperature through a lumen of the catheter can modify temperature of the shapeable portion which in turn can modify a shape and/or flexibility state of the shapeable portion. Modifying the shape of the shapeable portion can modify an angle at which a distal tip of the stylet extends relative to the central longitudinal axis. A user can then rotate and advance the distal tip to negotiate tortuous vascular pathways. Similarly, modifying a flexibility of the shapeable portion can facilitate negotiating tortuous vascular pathways.

摘要： Disclosed herein are medical systems and devices that include an elongate probe configured for insertion into a patient, where a multi-core optical fiber extends along the elongate probe. The optical fiber can include sensing core fibers that extend distally along the probe. The optical fiber can further include illumining core fibers to facilitate projection of light away from the distal end in various illumination patterns. The system includes a console having processors and logic stored in memory. The logic can facilitate singly projecting the illumination light in the various pattens. The logic can also extract an image from returning light and compare wavelengths between the illuminating light and the returning light to determine a motion of body elements.
