Claim:
A lead locking device, comprising: a lead engaging member having a distal end and a proximal end, said lead engaging member defining a lumen extending along a longitudinal axis between said distal end and said proximal end; and a mandrel disposed in said lumen and attached to said distal end of said lead engaging member, said mandrel extending along substantially an entire length of said lumen and protruding beyond a most proximal end of said lead engaging member and beyond the said distal end of said lead engaging member, wherein said lead engaging member has a first configuration adapted to be inserted into a lumen of a lead and a second configuration adapted to engage the lead from within said lumen of the lead, wherein the outer diameter of the section of said mandrel distally protruding from the said distal end of said lead engaging member is less than the outer diameter of the remainder of said mandrel, and a flexible coil disposed over said distally protruding section of said mandrel, wherein the distal end of said coil is fixedly attached to the distal end of said mandrel.
