A New Device For the Treatment of Thromboembolic Strokes

We present data concerning the design and testing of a new clot-sucking device for possible use in the extraction of blood clots that arise during thromboembolic strokes. Our data indicate that a jellylike mass of 0.02 g (of an artificial clot) can be removed from plastic tubing using this vortex-creating device, which has an optimal diameter of 1 mm, in conjunction with a 6F arterial catheter that is 110-cm long and using applied suction pressures of about 50 cm Hg.
