    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 tissue penetrating probe includes a distal tissue piercing end; a first electrode; a second electrode; and a dielectric element. A proximal end of the dielectric element is bonded to a distal end of the first electrode and a distal end of the dielectric element is bonded to a proximal end of the second electrode. The dielectric element is formed of a composite material including a fiber braid within a polymeric material.
