SYSTEMS AND METHODS FOR REDUCING PRESSURE AT AN OUTFLOW OF A DUCT

Abstract: various systems and methods are provided for reducing pressure at an outflow of a duct such as the thoracic duct or the lymphatic duct. a catheter system can include a catheter shaft configured to be at least partially implantable within a patient's vein, a flexible membrane attached to the catheter shaft, the flexible membrane being a collapsible, tube-like member having a lumen extending therethrough, and a single selectively deployable restriction member formed over a portion of the flexible membrane at substantially a midpoint between a proximal end of the flexible membrane and a distal end of the flexible membrane, the restriction member being configured to control a size of the lumen so as to direct a controlled volume of fluid from an upstream side of the restriction member to a downstream side the restriction member.
