Hemodialysis with an ELISIO™-H 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 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 dialyzers are composed of polyethersulfone fiber and are available in various sizes, which are differentiated by membrane surface area.
The provided text describes a 510(k) summary for the ELISIO™-H Hemodialyzer, a medical device. This type of regulatory submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than providing extensive details about a clinical study with acceptance criteria for device performance in the same way one might for a novel AI/software diagnostic device.
Therefore, many of the requested elements are not applicable or cannot be extracted from this document, as it pertains to a hemodialysis system and not an AI or imaging diagnostic device.
Here's an analysis based on the provided text, addressing the applicable points:
1. A table of acceptance criteria and the reported device performance
The document does not specify quantitative acceptance criteria in terms of performance metrics (e.g., sensitivity, specificity, or specific physical parameters with defined thresholds) or present a table of reported device performance against such criteria. The "Conclusion" states: "Testing performed on the ELISIO-H dialyzers indicates that they are safe, effective and perform as well as the legally marketed device models, when used in accordance with the instructions for use." This is a qualitative statement of efficacy in the context of substantial equivalence, not a detailed performance report.
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
This information is not provided. The document mentions "testing performed" but does not detail the nature of these tests (e.g., in vitro, animal, or human clinical trials), sample sizes, or data provenance.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This is not applicable to this type of device and submission. The ground truth for a hemodialyzer's performance would primarily be established through physical and chemical testing (e.g., clearance rates, ultrafiltration rates, biocompatibility) rather than expert interpretation of medical data from a test set.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. This concept is typically relevant for studies involving human interpretation of data, where multiple experts might be used to resolve discrepancies in diagnoses or interpretations.
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 a hemodialysis system, not an AI or imaging device that would typically involve human readers being assisted by AI.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Not applicable. The device is a physical medical device (hemodialyzer), not a standalone algorithm.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
The "ground truth" for a hemodialyzer's performance would be established through engineering and biological testing (e.g., direct measurement of solute clearance, ultrafiltration, pressure drops, blood-material interactions, and possibly in vivo biocompatibility or animal studies to simulate real-world conditions). The document does not detail these specific methods or outcomes. The basis for the substantial equivalence is the ELISIO™-H Hemodialyzer's composition and function being "safe, effective and perform as well as the legally marketed device models," implying that the performance metrics of the predicate devices serve as an implicit benchmark.
8. The sample size for the training set
Not applicable. The ELISIO™-H Hemodialyzer is a physical device, not an algorithm that requires a training set.
9. How the ground truth for the training set was established
Not applicable.
§ 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).
