  • Patent number: 5364345
    Abstract: A method of tubal recanalization comprising advancing an everting catheter adapted for dilatation and an endoscope to a position adjacent the site of a stenosis in an internal tubal passage of a patient. The everting catheter includes an endoscope lumen and the endoscope is within the endoscope lumen. The everting element 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be carried out prior to expansion of the everting element to locate the site as well as after the everting element has been retracted.
