摘要： 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.
摘要翻译：提供组织消融探针。所述组织消融探针包括细长轴，由所述细长轴承载的至少一个电极齿条，至少一个齿出口，所述电极齿可以从所述至少一个齿出口从所述细长轴展开并缩回到所述细长轴内，覆盖电极齿出口。护套可以例如对细长轴的外表面或细长轴的内表面进行排列。护套具有定位在电极齿出口上方的至少一个齿阀（例如狭缝），并且构造成当电极齿展开时打开，并且当电极齿被缩回时闭合。在一个实施例中，齿阀构造成响应于在电极尖的展开期间施加的压力而打开。在另一个实施例中，齿形阀构造成阻止生物材料进入细长轴内。在一个实施例中，鞘是柔韧的，使得齿可以更容易地阻碍生物材料的进入。

摘要： 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.
摘要翻译： RF消融装置包括探针组件，该探针组件具有细长插管，该插管具有设置在套管的外壁内部的内腔。细长插管包括形成在外壁内的多个槽，其提供对腔的通路。探针组件包括可滑动地设置在细长插管内的电极构件，电极构件包括构造成通过多个槽的多个尖齿。狭槽围绕套管的外壁以交错布置或图案布置。槽的交错布置可以用于插管上的电极的单极或双极布置。与现有设计相比，使用交错配置的电极的双极布置在更短的时间段内产生较大的消融区域。

摘要： 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., to proximally evert.
