| 1. A method of incorporating a tip into an endovascular device comprising:
providing a tubular end portion of an endovascular device, the tubular end portion further comprising a proximal end portion,
a distal end portion, an outlet opening in the distal end portion, a longitudinal bore extending through the tubular end portion
and in communication with the outlet opening, and at least a first pair of openings in an exterior surface of the tubular
end portion;
forming a counterbore in the distal end portion of the tubular end portion, wherein the step of forming the counterbore results
in the distal end portion comprising an increased internal diameter relative to an internal diameter in the proximal end portion;
providing a hollow tubular tip comprising a proximal end having at least first and second flanges, at least a first pair of
locking members protruding from an interior surface of the second flange;
positioning the first flange within the counterbore and positioning the second flange over an outer radial surface of the
tubular end portion; and
securing the tip onto the tubular end portion by mating the first pair of locking members with the first pair of openings.
