The PrisMax control unit is intended for:
· Continuous Renal Replacement Therapy (CRRT) for patients weighing 20 kilograms or more with acute renal failure and/or fluid overload.
• Therapeutic Plasma Exchange (TPE) therapy for patients weighing 20 kilograms or more with diseases where removal of plasma components is indicated.
All treatments administered via the PrisMax control unit must be prescribed by a physician.
The PrisMax System is intended for Continuous Renal Replacement Therapy (CRRT) for patients with acute renal failure and/or fluid overload. The goals of acute renal failure treatments are removal of waste products, restoration of acid-base balance; correction of electrolyte imbalances (e.g., hyperkalemia), patient fluid balance, nutritional support, and other conditions in which fluid removal is needed. PrisMax System offers four Continuous Renal Replacement Therapy (CRRT) options: Slow Continuous Ultrafiltration (SCUF), Continuous Veno-Venous Hemofiltration (CVVH), Continuous VenoVenous Hemodialysis (CVVHD), and Continuous Venovenous Hemodialfiltration (CVVHDF). The proposed device PrisMax, which is the subject of this Traditional premarket notification (510(k)), consists of the PrisMax Control Unit System, Blood Tubing Sets and Accessories. Specific to this submission, is the accessory for blood warming and a blood tubing set for Therapeutic Plasma Exchange (TPE2000).
Here's a breakdown of the acceptance criteria and the study information for the PrisMax System Version 2, based on the provided document.
It's important to note that this document is a 510(k) summary for a medical device and not a study report for an AI/algorithm-based device. Therefore, many of the requested categories (like sample sizes for test/training sets, number of experts, adjudication methods, MRMC studies, standalone AI performance, and ground truth establishment for AI) are not applicable to this submission, as it concerns a physical medical device (CRRT/TPE system) and its software/accessories, not an AI model.

§ 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).
