Mri catheter with ceramic reinforcement members

enhanced imaging by MRI (200) catheter comprising: an elongated body (210) having at least one lumen extending therethrough, further comprising the elongate body proximal end (220), a distal end (230), a circumference, a longitudinal axis (320) extending between said proximal and distal ends (220, 230) and a coaxial layer (320); and an operably proximate the distal end of the elongated body antenna arranged; and characterized in that: the coaxial layer (320) incorporates at least one elongated ceramic member (500), wherein the ceramic member is substantially covered with a coating (620) and the ceramic member includes knurled surface applied, and wherein filled coating surface applied splines allowing an overall flexibility such that the ceramic member can be bent without breaking.
