Hemodialysis with an ELISIO-H or ELISIO-M hemodialyzer is indicated for patients with acute or chronic renal failure when conservative therapy is judged to be inadequate. It also may be indicated in the treatment of patients intoxicated with poisons or drugs.
The device is for prescription use only.
This product is intended for single use only. The performance properties of reused dialyzers have not been established.
The ELISIO-H and ELISIO-M hemodialyzers are medical devices used as an artificial kidney system for the treatment of patients with renal failure. 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 ELISIO-H and ELISIO-M dialyzers are composed of polyethersulfone fiber and are available in various sizes, which are differentiated by membrane surface area.
The provided 510(k) summary for the Nipro ELISIO™-H and ELISIO™-M Hemodialyzers (K122347) describes a medical device, not an AI or software-based diagnostic tool. Therefore, many of the requested categories related to AI/algorithm performance, such as "number of experts used," "adjudication method," "MRMC comparative effectiveness study," "standalone performance," and "training set details," are not applicable.
The acceptance criteria and study are focused on demonstrating substantial equivalence to predicate devices through non-clinical performance testing for a physical medical device.
1. Table of Acceptance Criteria and Reported Device Performance
| Performance Measure | Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|---|
| Analyte Clearance: | Comparable to predicate devices (Baxter Xenium XPH and XPM) | "Results of these studies establish substantial equivalence" |
| - Urea | ||
| - Creatinine | ||
| - Phosphate | ||
| - Vitamin B12 and/or Inulin | ||
| Ultrafiltration Coefficient | Comparable to predicate devices (Baxter Xenium XPH and XPM) | "Results of these studies establish substantial equivalence" |
| Pressure Drop | Comparable to predicate devices (Baxter Xenium XPH and XPM) | "Results of these studies establish substantial equivalence" |
| Safety | Meets established safety standards and is comparable to predicates | "Testing performed... indicates that they are safe, effective and perform as well as the predicate devices" |
| Effectiveness | Meets established effectiveness standards and is comparable to predicates | "Testing performed... indicates that they are safe, effective and perform as well as the predicate devices" |
Note on Acceptance Criteria: The document states "Results of these studies establish substantial equivalence." This implies that the acceptance criteria were that the ELISIO™ hemodialyzers performed comparably to, or at least no worse than, the identified predicate devices (K083778 Baxter Xenium XPH Hemodialyzer and K093120 Baxter Xenium XPM Hemodialyzer) for the measured parameters. Specific numerical thresholds are not provided in this summary.
2. Sample Size Used for the Test Set and the Data Provenance
The document does not specify exact sample sizes for the non-clinical tests (e.g., how many dialyzers of each type were tested). The data provenance is also not detailed, as these are non-clinical (laboratory/bench) studies on manufactured devices rather than studies on patient data.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
Not applicable. This is a physical medical device; its performance is evaluated through objective physical and chemical measurements in a laboratory setting, not by human expert interpretation of data or images.
4. Adjudication Method for the Test Set
Not applicable. There is no human interpretation or subjective assessment that would require adjudication.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done, If so, What Was the Effect Size of How Much Human Readers Improve with AI vs without AI Assistance
Not applicable. This is not an AI/software-assisted diagnostic device.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done
Not applicable. This is not an AI/algorithm-based device.
7. The Type of Ground Truth Used
The "ground truth" for the performance characteristics (analyte clearance, ultrafiltration coefficient, pressure drop) would be established through:
- Physical and Chemical Measurements: Direct, standardized laboratory measurements of the dialyzers' performance using established methods and calibrated equipment.
- Comparison to Predicate Devices: The performance metrics of the ELISIO™ dialyzers were compared directly to the performance of the legally marketed predicate devices to establish substantial equivalence.
8. The Sample Size for the Training Set
Not applicable. This is not an AI/machine learning device that requires a training set.
9. How the Ground Truth for the Training Set Was Established
Not applicable. This is not an AI/machine learning device.
§ 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).
