Device Description

The HemoSphere Alta Advanced Monitoring Platform is the next-generation platform that provides a means to interact with and visualize hemodynamic and volumetric data on a screen. It incorporates a comprehensive view of patient hemodynamic parameters with an intuitive and easy user interface. The HemoSphere Alta Advanced Monitoring Platform is designed to provide monitoring of cardiac flow with various core technologies coupled with other technologies-based features such as Algorithms and Interactions. It integrates existing hemodynamic monitoring technologies into a unified platform.

AI/ML Overview

The HemoSphere Alta Advanced Monitoring Platform's FDA 510(k) clearance letter and associated 510(k) summary (K252533) primarily focus on software modifications and the integration of previously cleared hardware components to an existing platform (K242451). The document states that no new clinical testing was performed in support of the subject 510(k). Therefore, the information provided mainly pertains to performance verification studies rather than standalone clinical performance studies involving ground truth establishment by experts for a novel algorithm.

However, based on the provided text, we can infer the acceptance criteria and study information as follows:


1. Table of Acceptance Criteria and Reported Device Performance

The document describes several verification activities without providing specific numerical acceptance criteria for each, except implicitly stating "All tests passed" or "All acceptance criteria were met."

Acceptance Criteria CategoryReported Device Performance
UsabilityDemonstrated that intended users can perform primary operating functions and critical tasks without usability issues that may lead to patient or user harm. All acceptance criteria were met for human factors validation.
System Verification (Non-Clinical Performance)Met predetermined design and performance specifications. Differences in design and materials did not adversely affect safety and effectiveness. All tests passed.
Electrical Safety and EMCComplies with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-6, IEC 60601-1-8, IEC 62304, IEC 62366-1, IEC 60601-2-34, IEC 60601-2-57, IEC 60601-2-49, IEC 60529-1, and IEC 80601-2-49. All tests passed.
Software VerificationExtensive software verification testing ensured safety for use, demonstrating substantial equivalence to predicate devices. All tests passed.

2. Sample Size Used for the Test Set and Data Provenance

  • For Usability Study: The document mentions "the intended users." It does not specify the numerical sample size of users or the provenance of the data (e.g., retrospective or prospective, country of origin).
  • For Non-Clinical Performance (Bench Simulation): "Measured and derived parameters were tested using a bench simulation." No sample size in terms of patient data or data provenance is applicable here, as it's a bench test.
  • For Software Verification: "Extensive software verification testing was conducted." No specific sample size of test cases or data provenance is provided.
  • For Clinical Performance: "No new clinical testing was performed in support of the subject 510(k)." This indicates no patient-level test set data was used for this specific submission. The algorithms within the device (e.g., GHI, Smart Wedge, HPI, CAI, RVP, RVCO, AFM) likely had clinical performance studies for their initial clearances, but those details are not provided in this 510(k) for the HemoSphere Alta platform updates.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

  • As "no new clinical testing was performed" for this 510(k) submission, there is no mention of experts establishing ground truth for a new clinical test set.
  • For the Usability Study, "intended users" participated, implying clinical professionals, but their specific qualifications or their role in establishing "ground truth" (beyond identifying usability issues) are not detailed.

4. Adjudication Method for the Test Set

  • Since no new clinical test set data with expert adjudication is described in this submission, no adjudication method is mentioned.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

  • The document does not mention any MRMC comparative effectiveness study comparing human readers with and without AI assistance for this 510(k) submission.

6. Standalone Performance (Algorithm Only Without Human-in-the-Loop)

  • While the device contains various algorithms (e.g., GHI, HPI, Smart Wedge, CAI, RVP, RVCO, AFM), this 510(k) primarily addresses software updates and hardware integration to an existing platform. It doesn't detail standalone performance studies for these specific algorithms within this document. The description of these algorithms (e.g., "additional information regarding the patient's physiological condition for reference only and no therapeutic decisions should be made based solely on the GHI algorithm predictions") implies a non-standalone, assistive role, but explicit standalone performance studies are not part of this submission's provided information.

7. Type of Ground Truth Used

  • "No new clinical testing was performed." Therefore, for this specific 510(k) submission, no new patient-level ground truth (expert consensus, pathology, outcomes data, etc.) was established for performance evaluation of new algorithms or features. The verification activities relied on bench simulations and usability testing, not clinical ground truth.

8. Sample Size for the Training Set

  • The document pertains to the clearance of a device (HemoSphere Alta Advanced Monitoring Platform) with software modifications and hardware integration, not the development or training of new AI algorithms. Therefore, no information on the sample size of a training set is provided. The algorithms included in the HemoSphere Alta system (e.g., GHI, HPI, CAI) would have been developed and trained using data sets prior to their initial clearance. This current 510(k) does not detail those previous training sets.

9. How the Ground Truth for the Training Set Was Established

  • Similar to the training set sample size, this information is not provided in this 510(k) document, as it focuses on software updates and hardware integration to an already cleared platform, not the initial development and training of novel algorithms.
