Right ventricular injection catheter; right ventricular angiographic method; and method of monitoring septal wall motion

摘要: A novel right ventricular injection catheter is disclosed having a balloon tip for disposition in non-irritable portion of the pulmonary artery, and distinct lumen terminating plurality perforations located 6-8 centimeters from through which materials may be injected into ventricle. Using this catheter, it has been found that premature beats avoided, thereby permitting observation normal intraventricular septal motion.
