Right heart ejection fraction and cardiac output catheter |
摘要 |
An apparatus for injecting a fluid into the heart and making temperature measurements within the pulmonary artery comprising an elongated flexible tube having a distal end portion, a temperature sensor mounted on the distal end portion, a peripheral wall, at least one lumen extending longitudinally within the tube and an injectate port opening in the peripheral wall proximally of the temperature sensor. The tube can be advanced through a vein, the right atrium and the right ventricle to place the distal end portion in the pulmonary artery and the injectate port in the right atrium facing generally toward the inferior vena cava. The temperature sensor is oriented on the distal end portion so as to materially reduce the likelihood that it will contact the wall of the pulmonary artery during use.
