The AcQCross™ Qx Integrated Transseptal Dilator/Needle is indicated to puncture the interatrial septum to gain access to the left side of the heart whereby various cardiovascular catheters are introduced.
AcQCross™ Qx combines the conventional vessel dilator and transseptal needle into a single device. AcQCross™ Qx consists of an elongated shaft with a tapered tip and central lumen to track over a guidewire. The lumen of AcQCross™ Ox is fitted with a hollow stainless steel transseptal needle. Both the shaft and needle are connected to the proximal handle of AcQCross™ Qx. The lumen of the needle will allow for guidewires up to 0.032" in diameter. The needle is affixed to a spring-tensioned actuator in the handle of AcQCross™ Ox that prevents needle extension until the operator purposely advances the needle via a slider button located on the outer surface of the handle. The proximal handle is fitted with a Luer connector to gain access to the central lumen of the needle. The handle is also fitted with an electrical connector that allows for monitoring intracardiac electrograms (EGMs) from the needle while in the heart utilizing the EGM adapter cable, and/or allows for the application of radiofrequency (RF) current from an electrosurgical generator to facilitate the septal puncture utilizing the ES adapter cable. AcQCross™ Qx is for single-use only and is provided sterile.
This document is an FDA 510(k) premarket notification for a medical device called the AcQCross™ Qx Integrated Transseptal Dilator/Needle. It's a submission seeking clearance for new models of an existing device, asserting substantial equivalence to a previously cleared predicate device (K210685).
Based on the provided information, the request is to "Describe the acceptance criteria and the study that proves the device meets the acceptance criteria." However, it's crucial to understand that this document describes a submission for a device (a physical medical tool), not a PREDICATE AI/ML device or a study proving AI/ML model performance in the context of typical AI acceptance criteria (e.g., sensitivity, specificity, AUC).
Therefore, I cannot directly extract "acceptance criteria" and "study results" in the way one would for an AI/ML diagnostic or predictive model, nor can I fill out the table with metrics like sensitivity, specificity, accuracy, etc. The "performance data" section of this document refers to bench testing of a physical medical device.
I will interpret the request within the context of the provided document, focusing on the device's functional performance and the evidence provided to the FDA for its substantial equivalence, which is how "acceptance criteria" and "study proving it meets criteria" are addressed for this type of medical device.
Acceptance Criteria and Study for the AcQCross™ Qx Integrated Transseptal Dilator/Needle (K220047)
The document describes the acceptance criteria and supporting studies in terms of substantial equivalence to a predicate device (AcQCross™ Qx, K210685). The "acceptance criteria" are implicitly met if the new models perform "as intended" and present "no unacceptable risks" compared to the predicate, with specific focus on dimensional modifications facilitating compatibility with different transseptal sheaths. The "study that proves the device meets the acceptance criteria" refers to bench testing and leveraging existing data from the predicate device.
1. Table of Acceptance Criteria (Functional Performance) and Reported Device Performance
For this physical medical device, "acceptance criteria" are related to its mechanical and electrical function, material compatibility, and sterile presentation, demonstrating it functions similarly to the predicate device despite minor dimensional changes. The "reported device performance" refers to the successful completion of these tests.
| Acceptance Criteria (Functional Performance Aspect) | Reported Device Performance (as demonstrated by testing) |
|---|---|
| Dimensional Compatibility: New models must facilitate compatibility with different transseptal sheaths. | Dimensional changes (effective dilator length, effective needle length, handle lock feature) were specifically tested and found to be compatible with new sheaths. Minor dimensional differences do not impact safety/effectiveness. |
| Material Safety (Biocompatibility): Materials must be safe for patient contact. | Biocompatibility testing performed on the predicate device (K210685) found the materials (Polyethylene Hexene Copolymer, ethylene homopolymer, barium sulfate with blue colorant, 304 Stainless steel, polycarbonate) to be safe. New models use identical materials, thus no additional testing was required. |
| Sterility Assurance: Device must be sterile at point of use. | Sterilization validation performed on the predicate device (K210685) in accordance with ISO 11135 (Ethylene Oxide) demonstrated a sterility assurance level (SAL) of 10-6. New models were adopted into the existing process per AAMI TIR28, requiring no further process validation. |
| Electrical Safety & EMC: Electrical components must be safe and not interfere with other devices. | Electrical safety and Electromagnetic Compatibility (EMC) testing performed on the predicate device (K210685) in accordance with ANSI/AAMI IEC 60601-1, IEC 60601-1-2, and IEC 60601-2-2. Modifications do not impact these parameters, thus no additional testing was required. |
| Mechanical Integrity/Functionality: Device must operate as intended (e.g., tensile strength, kink resistance, needle actuation). | Bench testing was performed focusing on the modifications, including: - Shaft to handle tensile - Length compatibility - Snap engagement - Kink resistance - Needle actuation - Visual inspection - Aspiration/flushing - Electrical continuity (Other tests leveraged from predicate: Dimensional Verification, Surface Inspection, Tip Curve Retention, System Leak- Air Leakage- Luer Fitting, Needle to Button Tensile, Luer to Hypotube Tensile, Pushability/Trackability, Corrosion Resistance, Radiopacity). The nonclinical bench data support the safety of the device and demonstrate that it performs as intended. |
2. Sample size used for the test set and the data provenance:
- Test Set: The document does not specify exact sample sizes for each bench test (e.g., number of devices tested for tensile strength, kink resistance, etc.). However, it indicates these tests were performed on "AcQCross™ Ox" (the new models) focusing on the dimensional modifications.
- Data Provenance: The studies are bench testing conducted by the manufacturer (Acutus Medical, Inc.). This is not "data" in the sense of patient data (retrospective/prospective, country of origin). It's engineering and performance testing of the physical product.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
This question is not applicable in the context of this device. "Ground truth" established by experts (e.g., radiologists for image interpretation) is relevant for diagnostic AI/ML devices. For a physical medical device like a transseptal dilator/needle, the "truth" is determined by engineering specifications and objective bench test results, often against recognized standards (e.g., ISO standards). No human expert "labels" or "interprets" a performance test in this manner.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
This question is not applicable. Adjudication methods (concensus among multiple readers) are relevant for clinical studies, particularly in diagnostic imaging. For bench testing of a physical device, results are typically quantitative measurements and characterizations against pre-defined engineering limits or established standards.
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:
This question is not applicable. An MRMC study is relevant for evaluating the impact of AI on human performance in diagnostic tasks. This submission is for a physical, interventional medical device, not an AI/ML diagnostic tool. There is no "human-in-the-loop" performance improvement measured.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
This question is not applicable. This refers to an AI algorithm's independent performance. The AcQCross™ Qx is a physical medical device, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
The "ground truth" for this device's performance testing is based on engineering specifications, direct measurements, and compliance with recognized industry standards (e.g., ISO 11070:2014, ISO 10555-1:2013 for general requirements, AAMI/ANSI/ISO 10993-1:2009 for biocompatibility, ISO 11135:2014 for sterilization, ANSI/AAMI IEC 60601 series for electrical safety/EMC). For example, a "kink resistance" test's ground truth would be whether the device meets a pre-defined maximum kink angle or maintains patency under a certain force, rather than an expert opinion.
8. The sample size for the training set:
This question is not applicable. This device does not use an "AI training set." Its design is based on engineering principles and knowledge gained from the predicate device, not machine learning.
9. How the ground truth for the training set was established:
This question is not applicable as there is no AI training set.
