Abstract: A distal end portion of a medical device may comprise: a first portion having a groove around a perimeter of an outer surface of the first portion; a cover disposed around the outer surface of the first portion, and disposed within the groove; and a second portion having a tab protruding radially inward from an inner surface of the second portion. The tab may be received within the groove, radially outward of the cover.

Abstract: 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.
Abstract translation: 提供消融探针和制造消融探针的方法。 探针包括探针轴和单体电极元件。 一体电极元件包括位于轴的远端的公共电极基座和从电极基座向远侧延伸的多个电极齿。 可以通过从导电细长构件的第一端向细长构件的相对的第二端形成分隔（例如狭缝或狭槽）来产生电极元件。 或者，分隔可以由导电片的第一端朝向片的相对的第二端形成，然后弯曲或滚动以形成细长构件。 在任一情况下，公共电极基座可以单独地安装到探针轴上，或者探针轴可以由细长构件形成，在这种情况下，电极基座将与探针轴一体化为一体结构。 电极尖齿可以是任意成形的，例如，以近端倾斜。

Abstract: 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.
