Abstract
Disclosed herein are medical systems, devices, and methods for performing vascular treatments and diagnoses. A vascular device include an optical fiber including a single fiber core disposed offset from a central axis of the optical fiber. The single fiber enables logic of the system to perform determine multiple conditions of the device and the patient. The conditions may include one or more of blood flow parameters, infusate delivery parameters, location of the device within the patient, pH of the blood, oxygen level of the blood, damage to the optical fiber, or core temperature of the patient. The elongate medical device may be a catheter, a stylet, a guidewire, or a probe.
Claims5
A medical system, comprising:
- an elongate medical device configured for insertion within a blood vessel of a patient, the elongate medical device comprising:
- an optical fiber extending along a longitudinal length of the elongate medical device to a distal end of the elongate medical device, the optical fiber having a single core fiber extending along the optical fiber, the single core fiber disposed radially offset from a central axis of the optical fiber, the single core fiber including a plurality of sensors distributed along the longitudinal length, each sensor of the plurality of sensors configured to (i) reflect a light signal of a different spectral width based on received incident light, and (ii) change a characteristic of the reflected light signal based on a state of the optical fiber;
- and
- a console including:
- a light source optically coupled with the optical fiber via an optical connector;
- an optical receiver optically coupled with the optical fiber via the optical connector;
- a display;
- a processor;
- and
- a non-transitory computer-readable medium having stored thereon logic that, when executed by the processor, causes operations including:
- projecting via the light source a light distally along the optical fiber;
- receiving via the optical receiver the reflected light signal from the plurality of sensors;
- processing the reflected light signal by the processor to determine the state of the optical fiber based on the reflected light signal;
- and
- communicating the state to a user via the display, wherein the state includes a temperature.
