1. A catheter, comprising:
an elongated tubing including an opening at a distal end of the tubing, the tubing being formed by an axial wall defining a lumen extending between a proximal end of the tubing to the distal end of the tubing;
a septum positioned across the opening of the tubing;
a first micro-lumen formed in the septum;
a plurality of micro-lumens formed along a circumference of the wall forming the tubing;
a first core fiber residing within the first micro-lumen; and
a plurality of core fibers each residing within a different micro-lumen of the plurality of micro-lumens, wherein at least one of the plurality of micro-lumens is sized with a diameter to fixedly retain one of the plurality of core fibers, such that there is no spacing between a lateral surface of the one of the plurality of core fibers and an interior wall surface of the at least one of the plurality of micro-lumens,
wherein:
a plurality of sensors are distributed along a longitudinal length of both the first core fiber and each of the plurality of core fibers and each sensor of the plurality of sensors being 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 for use in determining a physical state of the catheter,
a characteristic of the reflected light signal for the plurality of core fibers is compared with a characteristic of the reflected light signal for the first core fiber to determine the physical state of the catheter, and
the characteristic of the reflected light signal is configured such that the physical state of the catheter is determined utilizing machine-learning techniques that include accessing a data store with pre-stored data, including image data, pertaining to different regions of the catheter in which the plurality of core fibers experienced a similar characteristic of the reflected light signal.

13. A catheter, comprising:
an elongated tubing including a distal end, the tubing being formed by an axial wall defining a lumen extending between a proximal end of the tubing to the distal end of the tubing;
a septum positioned across the distal end of the tubing;
a first micro-lumen formed along an axis central to a cross-section of the distal end of the tubing;
one or more micro-lumens formed along a circumference of the wall forming the tubing;
a first core fiber residing within the first micro-lumen; and
one or more core fibers each residing within a different micro-lumen of the one or more micro-lumens,
wherein at least one of the one or more micro-lumens is sized with a diameter to fixedly retain one of the one or more core fibers, such that there is no spacing between a lateral surface of the one of the one or more core fibers and an interior wall surface of the at least one of the one or more micro-lumens, and
wherein:
a plurality of sensors are distributed along a longitudinal length of both the first core fiber and each of the one or more core fibers and each sensor of the plurality of sensors being 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 for use in determining a physical state of the catheter,
a characteristic of the reflected light signal for the one or more core fibers is compared with a characteristic of the reflected light signal for the first core fiber to determine the physical state of the catheter, and
the characteristic of the reflected light signal is configured such that the physical state of the catheter is determined utilizing machine-learning techniques that include accessing a data store with pre-stored data, including image data, pertaining to different regions of the catheter in which the one or more core fibers experienced a similar characteristic of the reflected light signal.
