Appeal No. 2001-1472
Application 08/772,878
delivery tip associated with such a probe wherein the tip (e.g.,
as seen in Figure 2 of the application) has an enlargement (40)
at an end thereof providing an enlarged annular flat surface
transverse to the longitudinal axis of the tube for engaging the
calculi. The tip also includes a restriction (42) at the distal
end of the tip for preventing debris from the concretion or
calculi from entering the internal passageway of the probe until
it has been reduced to a sufficiently small size to allow it to
be aspirated through the probe without plugging. Independent
claim 22 is representative of the subject matter on appeal and a
copy thereof may be found in the Appendix to appellant’s brief.
