An ablation probe and method of manufacturing the ablation probe are provided. The probe comprises a probe shaft and a unibody electrode element. The unibody electrode element comprises a common electrode base located at the distal end of the shaft, and a plurality of electrode tines distally extending from the electrode base. The electrode element may be created by forming divisions (such as slits or slots) from a first end of an electrically conductive elongate member towards an opposing second end of the elongate member. Alternatively, the divisions can be formed from a first end of an electrically conductive sheet towards an opposing second end of the sheet, and then bent or rolled to form the elongate member. In either case, the common electrode base can either be separately mounted to a probe shaft, or the probe shaft can be formed from the elongate member, in which case, the electrode base will be integrated with the probe shaft as a unibody structure. The electrode tines can be optionally shaped, e. g.

A tissue ablation probe is provided. The tissue ablation probe comprises an elongated shaft, at least one electrode tine carried by the elongated shaft, at least one tine exit from which the electrode tine(s) can be deployed from the elongated shaft and retracted within the elongated shaft, and a sheath covering the electrode tine exit(s). The sheath may, e. g. , line an exterior surface of the elongated shaft or an interior surface of the elongated shaft. The sheath has at least one tine valve (e. g. , a slit) positioned over the electrode tine exit(s) and configured to open when the electrode tine is deployed and to close when the electrode tine(s) is retracted. In one embodiment, the tine valve(s) is configured to open in response to pressure exerted during deployment of the electrode tine(s). In another embodiment, the tine valve(s) is configured to hinder the entry of biological material within the elongated shaft. In one embodiment, the sheath is pliable, such that the tine valve(s) can more easily hinder the entry of the biological material.

A RF ablation device includes a probe assembly that has an elongate cannula having a lumen disposed interiorly of an external wall of the cannula. The elongate cannula includes a plurality of slots formed within the external wall that provide access to the lumen. The probe assembly includes an electrode member that is slidably disposed within the elongate cannula, the electrode member including a plurality of tines configured for passage through the plurality of slots. The slots are disposed in a staggered arrangement or pattern about the external wall of the cannula. The staggered arrangement of slots may be used in a monopolar or bipolar arrangement of the electrodes on the cannula. A bipolar arrangement of electrodes using the staggered configuration produces larger ablation areas in a shorter period of time as compared to prior designs.
