Ablation probe

An ablation probe (100; 200) suitable for insertion through the working channel of an intraluminal delivery device comprises an applicator (102; 202) arranged to apply radiation to heat surrounding tissue. The probe also comprises a feeding cable (104; 204) arranged to supply electromagnetic energy to the applicator (102; 202). The probe further comprises a first coolant flow path (106). There is also a deformable member (110; 210) arranged to move between an insertion configuration in which insertion of the probe is facilitated and a deployed configuration. A second coolant path (108), via which coolant is able to flow, is provided by the deformable member (110; 210) when in the deployed configuration. The probe further comprises a tube arranged to house a distal portion of the feeding cable, and the deformable member surrounds at least part of the tube, and the tube is formed from an elastic material.
