a system and method for introducing medical devices within vasculature that incorporates a dual lumen introducer allowing a plurality of guidewires to be introduced without entanglement . the introducer further includes slits formed in the dual lumen introducer and a dilator or an inner member with grooves that facilitate easy removal of the introducer and dilator from vasculature . the dual lumen introducer maintains separation between guidewires . the slits in the dual lumen introducer and the dilator grooves allow removal from the guidewires by slipping the device off the guidewires without retracting them the entire guidewire length . a peel - away sheath protects the vasculature from the guidewires , prevents the dilator from slipping off the guidewires , and maintains access to an expanded vessel for the introduction of medical devices .
