Abstract
A medical electrode placement system including a stylet insertable within an electrode carrying lead to provide stability to the lead during electrode placement within the body. The stylet includes a knob secured to one end thereof and a lead engagement device mechanically connected to the knob for imparting movement to a lead in accordance with manipulation of the knob. In a preferred embodiment, the lead engagement device is spaced from the knob to accommodate differences in length from lead to lead and may take the form of a clamp. The lead engagement device may be formed of a body member having a lead accepting groove therein, the groove being configured to compress a lead of desired cross section when placed within the groove. Finger(s) may be provided to project into the lead accepting groove to further enhance the engagement of the lead. In some instances, x-rays may be employed to provide a view of the lead placement. In such instances, the knob may be provided with an extension to remove the hand of the physician from the x-ray or fluoroscopy field.
