Abstract: The dilator catheter accepts at least one or more medical components such as electrically conductive leads, wires, or catheter for a medical device and/or procedure. The dilator catheter provides an inner sleeve and an outer sleeve. The inner sleeve inserts into an opening of the outer sleeve. The opening of the outer sleeve is sized such that the inner sleeve will contact the outer sleeve to secure the inner sleeve within the outer sleeve. The inner sleeve and the outer sleeve provide an opening that extends throughout the dilator catheter. The user places the distal end of the dilator catheter at the desired location for introducing the medical component. The user then removes the inner sleeve to enlarge the opening. The user then directs the medical component(s) through the opening to the distal end of the dilator catheter for proper placement of the medical component(s).
