4. Fig. 3
Catheter with deflated balloon inserted distally and introduced into true lumen of ascending aorta with a guide wire (left). Balloon inflated at tear site. When entry is closed, blood does not flow in pseudolumen, and progress of dissection is stopped (right).

7. Fig. 6
Experimental results of indwelling of inflated balloon. In this case diameter of central passage of balloon is 40% of canine aorta. No significant effects were observed in the hemodynamics, including blood pressure and flow above and below balloon.
