A number of augering tips used on the instruments are disclosed along with a method for releasibly affixing augering tips to the instruments. In addition, a dottering tip is disclosed for use in procedures where it is desired to open a pathway without excising material from the obstructed site. A combined augering and dottering tip is disclosed for a procedure in which material displacement followed by excising of material from within an artery is accomplished without removal of the combined augering and dottering tip until the procedure is complete.
