METHOD OF TUBAL RECANALIZATION AND CATHETER SYSTEM THEREFOR

摘要

A method of tubal recanalization comprising advancing an everting catheter (11) adapted for dilatation and an endoscope (53) to a position adjacent the site of a stenosis (83) in an internal tubal passage (81) of a patient. The everting catheter includes an endoscope lumen (41), (23a), (203) and the endoscope is within the endoscope lumen. The everting element (17) is everted to a location within the stenosis and is then expanded to reduce the stenosis. When the tubal passage has been opened sufficiently, the everting element is retracted. The site of the stenosis is viewed using the endoscope and such viewing may be carried out prior to exapansion of the everting element to locate the site as well as after the everting element has been retracted.
