a substantial portion of the diameter of grasping member 103 preferably grasping member 103 is a single integral structure and gap 301 is only completely open on only one side of grasping member 103 additionally grasping member 103 is preferably fabricated of a bio compatible and bio stable material that possesses a relatively low durometer to cause grasping member 103 to be compressible for example grasping member 103 can be fabricated from a suitable silicone material in use when a lead is positioned within the burr hole of a patient grasping member 103 is placed around the lead using gap 301 when grasping member 103 is not compressed gap 301 possesses a width that is sufficiently greater than the diameter of the lead to prevent application of an excessive frictional force on the lead thus grasping member 103 can be placed on the lead at a distance away from the position where outer ring 101 is secured to the skull then grasping member 103 can be slid along the lead and into the outer ring without dislocating the lead within the patient the outside diameter of grasping member 103 is preferably smaller that the inside diameter of outer ring 101 thereby allowing the insertion of grasping member 103 into outer ring 101 to occur with little complication after grasping member 103 is placed around the lead and within outer ring 101 wedge member 102 as shown in isolation in fig4 is placed around grasping member 103 and within outer ring 101 to form the assembly shown in fig1 wedge member 102 preferably possesses a durometer that is greater than the durometer of grasping member 103.
