#$%^&*AU2019283880A120200123.pdf#####ABSTRACT A dilator for sheathless access to a vessel of a patient, having a distal portion with a maximal outer diameter that extends from a distal end to a guidewire exit port 5 and a proximal portion with a reduced profile that extends from the guidewire exit port to the proximal end and a lumen that extends between the distal end and the guidewire exit port. A first guidewire may be positioned within the vessel and the dilator advanced over the guidewire. A guide catheter may then be advanced over the dilator. -18-WO 2016/053993 PCT/US2015/052866 1/12 r'r4 rfM 00 00 -1 1-
