Abstract: In some examples, an extension includes a connector adapted to electrically couple to a proximal end of the therapy delivery element. An elongated extension body is attached to the connector. The elongated extension body includes a stylet coil having a stylet coil lumen. The stylet coil extends within the elongated extension body to the connector. A conductor assembly includes a plurality of insulated electrical conductors braided to extend around the stylet coil and electrically coupled to the connector. The conductor assembly includes an inner lumen with a diameter greater than an outside diameter of the stylet coil, wherein axial elongated of the elongated extension body reduces the inner diameter of the conductor assembly. A low durometer insulator extends around the conductor assembly. A stylet is sized to slide freely within the stylet coil lumen during implantation of the extension in the living body.

Abstract: A low-insertion force electrical connector for implantable medical devices includes a housing with a pair of opposing sidewalls each with center openings oriented generally concentrically around a center axis. An inner coil is located in a recess with a coil axis generally co-linear with the center axis of the center openings. The inner coil includes an outer diameter less than a recess diameter, and an inner diameter greater than a center opening diameter. An outer coil is threaded onto the inner coil. The outer coil has an outer diameter less than the recess diameter, and an inner diameter less than the center opening diameter. The outer coil is radially expanded within the recess in response to engagement with contact rings on the implantable medical device, such that the outer diameter of the outer coil is at least equal to the recess diameter.

Abstract translation: 在一些示例中，延伸部包括适于电耦合到治疗递送元件的近端的连接器。 细长的延伸体连接到连接器上。 细长延伸体包括具有探针线圈腔的探针线圈。 探针线圈在细长延伸体内延伸到连接器。 导体组件包括多个绝缘电导体，编织成围绕管心针线圈延伸并电耦合到连接器。 导体组件包括直径大于通管线圈外径的内腔，其中细长延伸体的轴向细长减小了导体组件的内径。 低硬度绝缘体围绕导体组件延伸。 探针的尺寸可以在植入生物体内的延伸部分时在探针线圈腔内自由滑动。
