1. A catheter assembly comprising:
a catheter tip assembly coupled to a distal end of a catheter body, the catheter tip assembly comprising:
a flexing structure configured to bend in response to an external force;
an electrode adjacent the flexing structure, the electrode comprising:
a distal end wall; and
a longitudinally extending inner wall intersecting with the distal end wall,
wherein the distal end wall and the inner wall define a cavity; and
a multi-core fiber comprising a plurality of cores and a distal end, wherein each of the plurality of cores extends from a proximal end to the distal end of the multi-core fiber, wherein at least one of the plurality of cores comprises a fiber Bragg grating and is configured to sense a shape of the flexing structure,
wherein the distal end of the multi-core fiber is disposed within the cavity and is in contact with a surface of the distal end wall of the electrode, and
wherein a distal end of the fiber Bragg grating is disposed within the cavity and is spaced apart from the distal end wall of the electrode.
