Abstract
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 includes sensing core fibers that extend distally along a flexible distal tip section having a bending flexibility that exceeds a flexibility of a main probe section. The optical fiber may further include illumining core fibers, imaging core fibers, and an electrical conductor. An electrode at the distal end provides for detection of an ECG signal. The distal tip section may also be steerable. The system includes a console having processors and logic stored in memory. The logic facilitates portraying of a shape of the elongate probe, an ECG waveform and/or an image of an interior of the patient. The elongate probe further includes a shape memory material defining a transition temperature.
