The invention relates to an agent delivery catheter, comprising a first hollow tube and a second hollow tube 2 which protrudes from a distal opening of the first hollow tube 1 and defines an agent delivery lumen 3 extending along the entire length of the catheter, wherein: the distal end of the first tube 1 is coupled to the second tube 2 to form an annular cavity 4 between the first tube 1 and the second tube 2, the annular cavity 4 being configured to accommodate a retractable stylet shaft 5； a ceramic member 6 which is disposed at the distal end of the first tube 1, in particular distally with respect to the distal opening of the first tube 1, encompasses the second tube 2 and couples the first tube 1 to the second tube 2, in particular via a third hollow tube 23 which encompasses the first tube 1 and the ceramic member 6； and a protective shrink-fit tube 7 is disposed radially on the outside of the ceramic member 6 and extends over at least the length of the ceramic member 6. Another aspect of the invention relates to an agent delivery system comprising such a catheter and a stylet which comprises a handle portion 15 and a ceramic shaft 5 which is configured to be accommodated within the annular cavity 4 of said catheter, wherein a shrink-fit tube 6 is disposed radially on the outside of the ceramic shaft 5 and in particular extends over at least the length of the ceramic shaft 5.
