The provided document is an FDA 510(k) clearance letter for the Cure Twist Female Catheter. It outlines the device, its indications for use, and a comparison to a predicate device, along with a summary of performance data. However, it does not contain the specifics of a study or acceptance criteria in the format requested, particularly for AI/machine learning device evaluation.

The document indicates that the device is a urological catheter, not an AI/ML device. Therefore, a study proving an AI device meets acceptance criteria, including specifics like sample sizes for test and training sets, expert consensus, MRMC studies, or ground truth establishment, would not be found in this type of clearance letter. The performance data points listed (sterilization, biocompatibility, packaging integrity, etc.) are standard for a physical medical device, not an AI algorithm.

Therefore, I cannot extract the requested information from the provided text for an AI/ML device. The "acceptance criteria" and "study that proves the device meets the acceptance criteria" in this document refer to the physical and mechanical properties of a catheter, validated through standard engineering and biological testing, not AI model performance.

Explanation of why the requested information cannot be provided from this document:

• Device Type: The Cure Twist Female Catheter is a physical medical device (urological catheter), not an artificial intelligence/machine learning (AI/ML) device.
• Performance Data Scope: The "Performance Data" section lists tests relevant to physical medical devices (e.g., sterilization, biocompatibility, packaging integrity, flow rate, tensile strength). These are not metrics or studies typically associated with evaluating AI/ML algorithms.
• Absence of AI/ML Specifics: There is no mention of deep learning models, algorithms, human readers, ground truth consensus for image or data interpretation, or any other elements that would be present in a study proving an AI device's performance.

If this were an AI device, the 510(k) summary would typically include details about:

• Clinical Performance Study: Often a standalone study or a multi-reader, multi-case (MRMC) study.
• Performance Metrics: Sensitivity, specificity, AUC, F1-score, accuracy, etc.
• Test Set Description: Number of cases, demographics, data provenance, and how ground truth was established.
• Training Set Description: Size and how ground truth was established.
• Human Reader Performance: If AI assistance improves human reader performance (MRMC).

Since the provided document pertains to a traditional physical medical device, those types of studies and acceptance criteria are not applicable or detailed within this clearance letter.

The drainage end of the device has an outlet to which a urine bag with a suitable connector can be connected. The catheter also contains a hydrophilic-coating and is sterilized by irradiation.

The primary packaging provides the sterile barrier and contains a proof of seal for identification of opened products.

The Luja Coude is available in one length (33cm) with a flexible tip and diameters of 8 Fr, 10 Fr, 12 Fr, 14 Fr, 16 Fr, and 18 Fr.

The provided FDA 510(k) clearance letter and supporting Traditional 510(k) summary pertain to a urological catheter (Luja Coudé) and its substantial equivalence to a predicate device. This document focuses on the mechanical and material properties of the catheter, not on an AI/software as a medical device (SaMD) or diagnostic imaging device.

Therefore, many of the requested details, such as MRMC comparative effectiveness studies, standalone algorithm performance, AI training/test sets, expert ground truth establishment, and complex adjudication methods, are not applicable to this type of medical device submission. These elements are typically required for AI/ML-based diagnostic devices where performance is measured in terms of diagnostic accuracy (e.g., sensitivity, specificity, AUC) and reader improvement.

The provided information focuses on bench testing (non-clinical performance) to demonstrate the device's physical and biological properties meet established standards and are equivalent to the predicate.

Here's an analysis of the provided text in relation to your questions, highlighting what is available and what is not:

Analysis of Acceptance Criteria and Study Proof for Luja Coudé Catheter

Based on the provided FDA 510(k) clearance letter and Traditional 510(k) summary, the Luja Coudé catheter demonstrates its performance through non-clinical (bench) testing and biocompatibility assessments, rather than clinical studies or AI/ML performance evaluations involving human readers.

1. Table of Acceptance Criteria and Reported Device Performance

The document states that "Biocompatibility and bench performance testing were conducted to verify the proposed subject devices with modified hydrophilic coating met the pre-determined acceptance criteria per specified requirements." It also states, "The subject devices met the pre-determined acceptance criteria after simulated shipping distribution and aging cycle per specified performance requirements."

However, the specific numerical acceptance criteria or the exact reported performance values are not detailed in this public summary. Instead, the summary lists the tests conducted and confirms that the device met the criteria.

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

• Sample Size for Test Set: The document does not specify exact sample sizes for each non-clinical test (e.g., number of catheters tested for friction, kink, etc.). It only states that "Testing was performed on final, finished, and sterilized devices." This is typical for bench testing where the number of units tested is governed by standard protocols (e.g., ISO, ASTM, internal methods) to achieve statistical confidence for manufacturing and design verification, but individual numbers are not usually disclosed in 510(k) summaries unless a specific, novel statistical method for performance testing is employed.
• Data Provenance: The studies are "non-clinical" (bench testing). Therefore, concepts like "country of origin of the data" or "retrospective/prospective" studies do not apply in the context of human subject data. The device is manufactured by Coloplast A/S in Humlebæk, Denmark, and the tests would have been performed in a controlled laboratory environment.

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

• Not Applicable. For this type of device (a physical urological catheter), "ground truth" is established through physical measurements, chemical analysis, and standardized biological assessments in a lab setting, not by human experts interpreting clinical data (like radiologists interpreting images). The "experts" involved would be engineers, material scientists, and microbiologists conducting the tests.

4. Adjudication Method for the Test Set

• Not Applicable. Adjudication methods (e.g., 2+1, 3+1) are used to resolve discrepancies among human readers/experts in diagnostic studies, typically for AI/ML device validation. This is not relevant for the bench testing of a physical catheter.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, and the effect size of how much human readers improve with AI vs without AI assistance

• No. An MRMC study is relevant for AI/ML-driven diagnostic devices where the AI assists human readers. This device is a physical medical instrument, not an AI diagnostic tool.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done

• No. This question applies to AI algorithms. The Luja Coudé is a physical catheter designed for direct patient use via insertion, not an algorithm.

7. The Type of Ground Truth Used

• For this device, the "ground truth" is based on:
  • Standardized Bench Test Measurements: Objective physical properties (e.g., friction coefficients, kink resistance, dimensions, pH, osmolality) measured against international and proprietary Coloplast standards (ISO 20696, Coloplast TMs).
  • Biocompatibility Testing: Laboratory assays and in-vivo animal models (for systemic toxicity, irritation, sensitization) that demonstrate the material's safety in a biological environment, conforming to ISO 10993 standards.
  • Sterility Assurance Level (SAL): Defined by microbial inactivation standards (SAL 10⁻⁶).

8. The Sample Size for the Training Set

• Not Applicable. The concept of a "training set" is for AI/ML models. This device does not use an AI/ML model. The design and manufacturing process for the catheter would involve extensive development and testing, but not in the sense of an "AI training set."

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

• Not Applicable. As there is no AI training set, there is no ground truth to establish for it. The development of the catheter relies on established engineering principles, material science, and manufacturing quality control.

Summary: The provided document is a 510(k) summary for a physical medical device (catheter) that relies on non-clinical bench testing and biocompatibility assessments to demonstrate substantial equivalence and safety/effectiveness. It does not involve AI/ML technology or human reader studies. Therefore, many of the questions related to AI/ML device validation are not applicable.

Therefore, I cannot provide the requested information about acceptance criteria, performance, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, ground truth types, or training set details as these concepts apply to the evaluation of AI/ML algorithms.

The document discusses:

• Device Name: Cure Dextra® and Cure Catheter® Closed System
• Device Type: Intermittent urinary catheter
• Regulation Number: 21 CFR 876.5130 (Urological Catheter and Accessories)
• Predicate Device: Cure Catheter® Closed System (K080881)
• Non-Clinical Performance Testing: A summary of tests performed to demonstrate substantial equivalence, including sterilization validation, biocompatibility, sterile packaging, shelf-life, packaging integrity, diameter/shaft length, flow rate, tensile strength, and kink stability testing. These are standard tests for physical medical devices and not related to AI/ML performance.

The submission concludes that the subject devices are substantially equivalent to the predicate device based on these non-clinical performance tests.

Ask a specific question about this device

Luja Coude is indicated for use by patients with urine retention and patients with post void residual volume (PVR) due to neurogenic and non-neurogenic voiding dysfunction. The catheter is inserted into the urethra to reach the bladder allowing urine to drain. The product is for adult male patients only.

Luja Coude is a single-use, sterile catheter for intermittent urinary catheterization. The catheter has a flexible tip which contains several small holes (micro holes) by the tip creating a drainage zone which allows the urine to flow from the bladder through the catheter. The drainage end of the device has an outlet to which a urine bag with a suitable connector can be connected. The catheter also contains a hydrophilic-coating and is sterilized by irradiation. The primary packaging provides the sterile barrier and contains a proof of seal for identification of opened products. Luja Coude is available in one length (33cm) with a flexible tip and diameters of 8 Fr, 10 Fr, 12 Fr, 14 Fr, 16 Fr, and 18 Fr. Luja Coudé CH/FR 18 differs from the predicate device in the catheter size variants. Luja Coudé (predicate) includes French size 8 (CH8) through French size 16 (CH16) variants compared to the subject device which is a line extension to the Luja Coudé. The reference device supports the inclusion of the 18 Fr size variant.

The provided text describes the non-clinical performance testing for the Luja Coude (20108 Male CH18 - large packaging) device. Here's a breakdown of the requested information:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly present a table of acceptance criteria with corresponding device performance values for each test. Instead, it lists the types of tests conducted and generally states that the "properties meet the acceptance criteria" or "proposed subject devices met the pre-determined acceptance criteria."

Here's an inferred table based on the information provided:

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

• Sample Size for Test Set: The document does not specify the exact sample size for each test conducted. It generally states that "the 18 fr size was included in analysis for all worst-case scenarios and included in testing." This implies that a sufficient number of 18 Fr devices were tested to represent the product.
• Data Provenance: The data is from non-clinical in vitro and bench testing conducted by Coloplast A/S (Denmark), with the contact person based in Minneapolis, MN, USA. The studies are retrospective in the sense that they are internal corporate testing used for regulatory submission.

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

This information is not applicable as the studies described are non-clinical bench and lab tests for a medical device (urological catheter). There are no human subjects, images, or diagnostic outputs that would require expert consensus or ground truth establishment by medical professionals like radiologists. The "ground truth" for these tests comes from established engineering and regulatory standards (e.g., ISO, ASTM, Coloplast internal methods).

4. Adjudication Method for the Test Set

This information is not applicable for non-clinical bench testing. Adjudication methods are typically used in clinical studies or studies involving human interpretation (e.g., by multiple readers).

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 information is not applicable. The submission describes non-clinical performance testing for a urological catheter, not an AI or imaging diagnostic device. Therefore, no MRMC study, human reader improvement, or AI assistance is relevant.

6. If a Standalone (i.e. algorithm only without human-in-the loop performance) was done

This information is not applicable. The device is a physical urological catheter, not an algorithm or software.

7. The Type of Ground Truth Used (Expert Consensus, Pathology, Outcomes Data, etc.)

The ground truth for the non-clinical tests described is based on:

• Established international and national standards (e.g., ISO, ASTM).
• Internal Coloplast test methods and specifications, which are themselves derived from engineering principles and regulatory requirements for safe and effective medical devices.
• The physical and chemical properties of the device materials and design.

8. The Sample Size for the Training Set

This information is not applicable. The device is a physical medical device, not an AI algorithm that requires a training set. The "training" for the device's design and manufacturing comes from engineering and material science principles.

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

This information is not applicable as the device is not an AI algorithm and therefore does not have a "training set" in that context.
