    摘要： The disclosure relates to devices and methods for the treatment of edema, which devices use a restrictor for flow compensation. Devices and methods of the invention further use a flow-restrictor in the circulatory system, upstream of an intravascular pump, to balance pressure changes induced by the pump and to compensate for downstream flow. The device may be provided as an indwelling, intravascular catheter with a mechanical pump such as an impeller and a selectively deployable restrictor such as an inflatable balloon. Congestive heart failure or edema is treated by \ operating the pump in an innominate vein and using the restrictor for flow compensation, to restrict the upstream flow and thus amplify or maintain pressure reduction at the lymphatic outlet.

    摘要： The disclosure relates to devices and methods for the treatment of edema using a purge-free system. The invention provides devices and methods useful for treating edema by means of an indwelling catheter that is placed in a blood vessel of a patient and used to pump blood to cause a decrease in pressure at an outlet of a lymphatic duct. The catheter pumps blood by means of an impeller but is purge-free in that the catheter does not include a system for purging or flushing catheter components with a purge fluid. The purge-free catheter avoids blood-related mechanical complications such as clotting or thrombosis by means of an impermeable sleeve or shroud that protects moving parts of the impeller drive system.
