A guiding sheath for inserting guidewires or vascular catheters within a blood vessel includes an elongate body having plurality of axial lumens. At least some of the lumens project laterally from the body at preselected angles so that, when inserted therethrough, the guidewire or catheter will exit at said preselected angle to facilitate directing the guidewire or catheter to the proper location within the vascular system. Usually, the insertional sheath will include a primary axial lumen which is used for inserting the sheath on a guidewire to a location where a branching in the vascular system occurs. The sheath is then positioned under fluoroscopic guidance so that one of the lumens is then properly located to direct the guidewire or catheter in the desired direction.
