CHF Solutions, Inc. is a privately held manufacturer of innovative medical devices for cardiac care and the developer of the aquapheresis therapy and the Aquadex FlexFlow Fluid Removal system. Fluid overload is failure to eliminate excess fluid, primarily salt and water, from the body. While many conditions such as renal failure, metabolic disease and post surgical conditions may result in fluid overload, congestive heart failure is a leading cause. Aquapheresis therapy and the Aquadex FlexFlow Fluid Removal system are designed specifically for use by physicians to safely, effectively, and conveniently treat fluid overloaded patients by removing excess salt and water. With aquaphereis, the physician specifies the amount of fluid to be removed from a patient's blood at a controlled rate and the system does so in a highly controlled and effective way.
