Abstract
A large bore catheter has a guiding rail extending therethrough and an advance segment of the rail extends at least about 10 cm beyond the distal end of the catheter. The advance segment is advanced from the vena cava through the tricuspid and pulmonary valves of the heart into the central pulmonary artery while the distal end of the large bore catheter remains in the vena cava. The large bore catheter is thereafter distally advanced over the rail until the large bore catheter distal end is at least as far as the central pulmonary artery. The rail is thereafter proximally removed from the large bore catheter, and at least a portion of a clot is drawn from a pulmonary artery into the large bore catheter.
