An ablation probe (), comprising: an applicator () arranged to apply radiation to heat surrounding tissue; a feeding cable () arranged to supply electromagnetic energy to the applicator. The feeding cable comprises a distal portion () and a proximal portion (). The distal portion of the feeding cable has a distal cross sectional size and the proximal portion of the feeding cable has a proximal cross sectional size, wherein the distal cross sectional size is less that the proximal cross sectional size. The ablation probe further comprises a connector () arranged to mechanically and electrically couple the distal portion () of the feeding cable () to the proximal portion () of the feeding cable (). The connector comprises a joining member () comprising a proximal end () shaped to receive an end of the proximal portion () of the feeding cable and a distal end () shaped to receive an end of the distal portion () of the feeding cable.

Ablation probe

An ablation probe () suitable for insertion through the working channel of an intraluminal delivery device comprises an applicator () arranged to apply radiation to heat surrounding tissue. The probe also comprises a feeding cable () arranged to supply electromagnetic energy to the applicator (). The probe further comprises a first coolant flow path (). There is also a deformable member () arranged to move between an insertion configuration in which insertion of the probe is facilitated and a deployed configuration. A second coolant path (), via which coolant is able to flow, is provided by the deformable member () 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.

A microwave ablation probe (), comprising: an applicator () arranged to apply microwave radiation to heat surrounding tissue; a feeding cable () arranged to supply electromagnetic energy to the applicator; a coolant flow path () via which coolant is able to flow; and a choke arranged to reduce power reflected from the applicator () along the feeding cable (). The choke comprises a choke member () cooled by coolant flowing in the coolant flow path (). The choke member () extends between two points spaced apart in a direction having at least a component parallel to a longitudinal axis of the feeding cable. The choke member () comprises one or more turns extending around the longitudinal axis of the feeding cable. The choke member may be a spiral member ().
