No
The document explicitly states "Mentions AI, DNN, or ML: Not Found" and the device description focuses on mechanical ultrafiltration and software for control, without mentioning any AI/ML capabilities.
Yes
The device is marketed for "temporary (up to 8 hours) ultrafiltration treatment" and "extended (longer than 8 hours) ultrafiltration treatment" for patients with fluid overload, actively treating a medical condition.
No
The Aquadex FlexFlow System is indicated for removing excess fluid (ultrafiltration treatment) from patients, which is a therapeutic treatment. It does not diagnose conditions.
No
The device description explicitly states the system is comprised of a console mounted on a cart, proprietary software, and accessories (catheters, extensions, blood pump circuit), indicating it includes significant hardware components beyond just software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVDs are used to examine specimens from the human body. The Aquadex FlexFlow System directly treats the patient by filtering their blood. It does not analyze samples taken from the patient.
- The intended use describes a treatment. The system is used for "ultrafiltration treatment of patients with fluid overload." This is a therapeutic intervention, not a diagnostic test.
- The device description details a blood filtration system. It describes a "hollow-fiber hemofilter" and a "blood pump circuit," which are components of an extracorporeal blood treatment system.
Therefore, the Aquadex FlexFlow System is a therapeutic medical device, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The Aquadex FlexFlow™ System is indicated for:
• Temporary (up to 8 hours) ultrafiltration treatment of patients with fluid overload who have failed diuretic therapy, and
• Extended (longer than 8 hours) ultrafiltration treatment of patients with fluid overload who have failed diuretic therapy and require hospitalization.
All treatments must be administered by a health care provider, under physician prescription, both of whom having received training in extracorporeal therapies.

Device Description
The Aquadex FlexFlow System removes excess fluid from the patient in fluid overload by ultrafiltration of blood across a hollow-fiber hemofilter at the clinician selected rate. The system is comprised on a console mounted on a cart, proprietary software and accessories (venous access catheters, extensions and a blood pump circuit). Patient access is obtained via either peripheral or central venous veins.

§ 876.5860 High permeability hemodialysis system.
(a)
Identification. A high permeability hemodialysis system is a device intended for use as an artificial kidney system for the treatment of patients with renal failure, fluid overload, or toxemic conditions by performing such therapies as hemodialysis, hemofiltration, hemoconcentration, and hemodiafiltration. Using a hemodialyzer with a semipermeable membrane that is more permeable to water than the semipermeable membrane of the conventional hemodialysis system (§ 876.5820), the high permeability hemodialysis system removes toxins or excess fluid from the patient's blood using the principles of convection (via a high ultrafiltration rate) and/or diffusion (via a concentration gradient in dialysate). During treatment, blood is circulated from the patient through the hemodialyzer's blood compartment, while the dialysate solution flows countercurrent through the dialysate compartment. In this process, toxins and/or fluid are transferred across the membrane from the blood to the dialysate compartment. The hemodialysis delivery machine controls and monitors the parameters related to this processing, including the rate at which blood and dialysate are pumped through the system, and the rate at which fluid is removed from the patient. The high permeability hemodialysis system consists of the following devices:(1) The hemodialyzer consists of a semipermeable membrane with an in vitro ultrafiltration coefficient (K
uf ) greater than 8 milliliters per hour per conventional millimeter of mercury, as measured with bovine or expired human blood, and is used with either an automated ultrafiltration controller or anther method of ultrafiltration control to prevent fluid imbalance.(2) The hemodialysis delivery machine is similar to the extracorporeal blood system and dialysate delivery system of the hemodialysis system and accessories (§ 876.5820), with the addition of an ultrafiltration controller and mechanisms that monitor and/or control such parameters as fluid balance, dialysate composition, and patient treatment parameters (e.g., blood pressure, hematocrit, urea, etc.).
(3) The high permeability hemodialysis system accessories include, but are not limited to, tubing lines and various treatment related monitors (e.g., dialysate pH, blood pressure, hematocrit, and blood recirculation monitors).
(b)
Classification. Class II. The special controls for this device are FDA's:(1) “Use of International Standard ISO 10993 ‘Biological Evaluation of Medical Device—Part I: Evaluation and Testing,’ ”
(2) “Guidance for the Content of 510(k)s for Conventional and High Permeability Hemodialyzers,”
(3) “Guidance for Industry and CDRH Reviewers on the Content of Premarket Notifications for Hemodialysis Delivery Systems,”
(4) “Guidance for the Content of Premarket Notifications for Water Purification Components and Systems for Hemodialysis,” and
