An implantable medical lead includes one or more tines configured to extend and/or retract from a lead body. The implantable medical lead includes a torque member within the implantable medical lead and configured to rotate a drive shaft within the implantable medical lead. The drive shaft is threadingly engaged with an inner surface of the implantable medical lead and is configured to convert the rotation into lateral translation of the drive shaft. The one or more tines are configured such that the lateral translation of the torque member translates the one or more tines laterally. The one or more tines are each electrically connected to a conductor that extends through the lumen of the implantable medical lead and is electrically isolated from each other. 一种可植入医疗引线，该可植入医疗引线包括被配置为从引线主体延展和/或缩回的一个或多个尖齿。该可植入医疗引线包括扭矩构件，该扭矩构件在该可植入医疗引线内并且被配置为使驱动轴在该可植入医疗引线内旋转。该驱动轴与该可植入医疗引线的内表面螺纹地接合并且被配置为将该旋转转换为该驱动轴的横向平移。一个或多个尖齿被配置为使得该扭矩构件的该横向平移使该一个或多个尖齿横向地平移。该一个或多个尖齿各自电连接到导体，该导体延伸穿过该可植入医疗引线的内腔并且彼此电隔离。
