摘要：
Systems and methods are provided for performing a medical procedure within a patients body that involves a thoracic duct including an ostium communicating with the patients venous system. A distal end of a catheter is introduced through the patients venous system into a body lumen adjacent the ostium of the thoracic duct. An expandable member on the distal end of the tubular may be expanded adjacent the ostium, e.g., within the body lumen or the thoracic duct itself, and used to isolate the thoracic duct from the body lumen, whereupon a medical procedure may be performed via the thoracic duct. For example, lymphatic fluid may be removed from the thoracic duct through a lumen of the tubular member and/or one or more agents may be introduced into the thoracic duct through the tubular member.
