    • An implantable neurostimulation system includes both implantable and external components. Electrical connectivity between the external and implanted components is achieved through a plurality of feedthrough pins located within an insulative wall of a percutaneous port embedded in the skin. The percutaneous port has the general shape and appearance of a small thimble, embedded in the skin with its open end facing outwardly from the skin surface, and with its closed end located below the skin surface, thereby forming a cavity or dimple in the skin. Various plugs or cartridges can be removably inserted into the cavity of the percutaneous port, in various orientations, to facilitate appropriate connectivity between the external and implanted components of the system through selected ones of the feedthrough pins. A mesh edging secured around the periphery wall of the port promotes tissue ingrowth and vascularization, thereby forming a percutaneous seal around the port that prevents infection.
    • 植入式神经刺激系统包括可植入和外部组件。 外部和植入部件之间的电连接通过位于皮肤内的经皮端口的绝缘壁内的多个穿通针来实现。 经皮端口具有嵌入皮肤中的小套管的一般形状和外观,其开口端从皮肤表面向外,并且其封闭端位于皮肤表面下方,从而在皮肤中形成空腔或凹坑。 可以以各种取向将各种插头或药筒可移除地插入到经皮端口的空腔中,以通过选定的馈通针来促进系统的外部部件和植入部件之间的适当连接。 围绕端口的周围壁固定的网状边缘促进组织向内生长和血管形成,从而在端口周围形成防止感染的经皮密封。
