Abstract
An ablation probe comprising an elongate body extending a length along a longitudinal axis from a first end to a second end, the first end extending into a housing and the second end comprising an ablation probe tip configured for insertion into a biopsy tract in a patient. In example forms, the elongate body of the ablation probe can be inserted into a patient through an existing trocar needle or biopsy access cannula following completion of a biopsy. In other example forms, the elongate body of the ablation probe defines a lumen. In one example form, the lumen contains a wire for heating the ablation probe tip, which may be composed of graphite, a resistive metal, or another electrically-resistive material. In another example form, the lumen additionally contains a thermocouple or other temperature sensor for monitoring the temperature of the ablation probe tip. In any of the above example forms, use of the ablation probe to heat tissue following a biopsy effects cauterization of the tissue, stopping bleeding and reducing or preventing the seeding of additional tumors.
