Abstract:
1. A method for percutaneously and repeatedly accessing a body fluid such as blood in an anatomical vessel, comprising: obtaining an access tube having an access end and an anastomosis end with a conduit extending from the access end to the anastomosis end; anastomosing the anastomosis end of the access tube to the sidewall of an anatomical vessel, wherein the access tube has sufficient length so that the access tube extends percutaneously with the access end being extracorporeally positioned; occluding the conduit of the access tube with an occluder at the anastomosis end; removing the occluder to provide fluid communication between the lumen of the anatomical vessel and the conduit of the access tube; re-occluding the conduit of the access tube; and flushing the conduit with a flushing fluid after the conduit of the access tube has been re-occluded.
