An improved body stimulation lead wherein the electrode is isolated from extraneous forces imparted to the lead body. In a preferred embodiment, a plurality of lobes are formed in the lead body, the lobes being engageable with body tissue to maintain the position of the electrode and being deformable in response to extraneous forces to minimize the influence of such forces on the position of the electrode. In addition, the lead conductor is formed as a space-wound coil which provides additional stress relief. A stylet is insertable within the coil to temporarily straighten the lobes and to provide sufficient stability to the lead body for placement of the lead. |
