Abstract
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 ma…
