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