An ablation device comprises a reusable handle assembly (410) including a first electrical contact (422)； and a limited-use needle electrode assembly (450) releasably engagable with the reusable handle assembly. The limited-use needle electrode assembly includes a second electrical contact (472) configured to electrically couple to the first electrical contact to establish electrical communication between the reusable handle assembly and the limited-use needle electrode assembly. The second electrical contact is movable from a first position, wherein mechanical engagement of the reusable handle assembly and the limited-use needle electrode assembly is permitted, to a second position, wherein the second electrical contact (472) inhibits mechanical engagement of the reusable handle assembly (410) and the limited-use needle electrode assembly (450) to one another.
