Abstract:
1. A method for providing repeated access to a body fluid in an anatomical, native vessel, comprising: providing an occludable access tube having an anastomosis end; anastomosing the access tube at its anastomosis end to the sidewall of the anatomical vessel, without sutures, for fluid communication between the anatomical, native vessel and the access tube; occluding the access tube with an occluder at its anastomosis end to prevent the body fluid in the anatomical, native vessel from entering the access tube; opening the access tube by selectively moving the occluder so that the occludable access tube is no longer occluded to provide fluid communication between the anatomical, native vessel and the access tube; enabling fluid communication between the access tube and a device; and re-occluding the access tube.
