The 2008T BlueStar Hemodialysis Machine is indicated for acute and chronic dialysis therapy in a healthcare facility.
Additional therapy options for patients receiving hemodialysis include: Isolated Ultrafiltration, Sustained Low Efficiency Dialysis (SLED), and low volume hemodialysis (patients weighing ≥ 20kg and ≤ 40 kg). This machine accommodates the use of both low flux and high flux dialyzers. The SLED therapy option is not to be used for patients weighing ≤ 40 kg. The 2008T BlueStar Hemodialysis Machine is not to be used for plasma replacement therapies, for patients weighing less than 20 kg, or for renal therapies using substitution fluid.
The 2008T BlueStar Hemodialysis Machine is an electromechanical device. Software controls the machine during hemodialysis treatment, including fluid flow, mixing, heating, and alarms.
The 2008T BlueStar Hemodialysis Machine provides hemodialysis treatment by controlling and monitoring both the dialysate circuit and the extracorporeal blood circuit. The machine pumps blood from the patient's body through an extracorporeal circuit, one component of which is the dialyzer. The dialyzer contains a semi-permeable membrane that uses diffusion to transfer toxins and ultrafiltration to transport excess water from the blood into the dialysate circuit. In this separate dialysate circuit, the dialysate concentrates are mixed with purified water, heated, degassed, and delivered to the dialyzer. Balancing chambers control the incoming flow and outgoing flow of the dialysate fluid during ultrafiltration. During hemodialysis, the extracorporeal blood circuit is monitored for venous and arterial blood pressures as well as for the presence of air and blood.
The 2008T BlueStar Hemodialysis Machine has automation features (independent internal conductivity testing, auto priming, auto start, CDX auto on, assisted reinfusion) to minimize user workload and improve user experience. The 2008T BlueStar Hemodialysis Machine includes SLED (Sustained Low Efficiency Dialysis), Low Volume, and Isolated Ultrafiltration therapy options. The 2008T BlueStar Hemodialysis Machine also accommodates the use of the Patient Card system, a dialysis treatment information system.
Based on the provided FDA 510(k) Clearance Letter, the device in question is the 2008T BlueStar Hemodialysis Machine. This document is a Class II Medical Device submission, which means it relies on substantial equivalence to a predicate device, rather than a clinical trial proving new efficacy. Therefore, the "acceptance criteria" and "study that proves the device meets the acceptance criteria" in this context are focused on demonstrating substantial equivalence to a legally marketed predicate device, rather than establishing new clinical effectiveness benchmarks through a de novo study.
The primary study type proving the device meets the "acceptance criteria" for 510(k) clearance is a comparison to a predicate device and supporting non-clinical performance and safety testing.
Here's a breakdown of the requested information based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
The "acceptance criteria" for a 510(k) submission are typically related to demonstrating that the new device meets the same performance specifications as the predicate and does not raise new questions of safety or effectiveness. The reported device performance is presented as its features and specifications.
| Feature / Acceptance Criteria (Derived from Predicate) | Reported Device Performance (2008T BlueStar Hemodialysis Machine) |

| Indications for Use Equivalence | Identical to predicate. Includes acute and chronic dialysis therapy in a healthcare facility, with options for Isolated Ultrafiltration, SLED, and low volume hemodialysis (patients ≥20kg and ≤40kg). Accommodates low/high flux dialyzers. Restrictions: not for SLED on patients ≤40kg, plasma replacement, patients |
§ 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).
