tubular member 12 this pushing action is believed to so facilitate the removal of severed clot material that obturator 24 and tubular member 12 can be constructed with diameters thinner than those which might have only suction forces to remove severed clot material accordingly small diameter tubes may be used to remove clots of relatively high density aperture 34 and proximal port 18 cofunction as a valve to permit the flow of irrigant only upon a severing of a blood clot bc by cutting edge 28 of obturator 24 during the pressurization of obturator 24 by the irrigant from reservoir 30 obturator 24 is juxtaposed to intermediate port 16 so as to prevent the flow of pressurizing fluid into bypass vbp this juxtaposition occurs periodically inasmuch as the invention contemplates an alternating cycle initially a vacuum and other assist devices suck clots into the tubular clot removal device only after that has been accomplished and the obturator changes position does the pressure cycle commence during which the obturator and or pressurized saline solution ejects the clot material as shown in fig2 cutting edge 28 is a circular edge provided by beveling obturator 24 at a distal end thereof as shown in fig3 an obturator element 36 insertable inside tubular member 12 is provided at a distal.
