A novel catheter is described. The catheter comprises a handle, an inner sheath providing an inner sheath lumen extending along a first length from a proximal inner sheath portion supported by the handle to a distal inner sheath portion connected to a cage gripper, and an outer sheath having a second length extending from a proximal outer sheath portion supported by the handle to a distal outer sheath portion connected to a cage housing. The inner sheath rotatably resides inside the outer sheath with the cage gripper rotatably housed inside cage housing. During a surgical procedure, a distal bridge portion of the inner sheath is connected to an opening in the lead sidewall with the lead received inside the cage housing. A gear knob is manipulated to cause the inner sheath to rotate with respect to the outer sheath so that the cage gripper is moved from an un-deployed position housed inside the cage gripper to a deployed position completely surrounding the lead connected to the distal bride. The catheter connected to the lead is moved into and to a desired location in a vasculature. Then, a screw driver is inserted through the housing and inner sheath lumens and into the lead and manipulated to screw the distal electrode into body tissue. Manipulating the gear knob causes the inner sheath to rotate the cage gripper from the deployed to the un-deployed position and then the catheter is separated from the lead and removed from the vasculature, leaving the lead behind.
