A new pervenous non-traumatic screw-in electrode has been developed and tested in 61 patients. Dislocation of this electrode occurred in 2 instances (3.3%) and an increase in threshold (exit-block) in 3 cases (5%) necessitated repositioning of the electrode.
一种新型经静脉无创旋入式电极已被研发出来，并在61例患者中进行了测试。该电极发生脱位2例（3.3%），阈值升高（出口阻滞）3例（5%），这使得电极需要重新定位。
