The Mentor ObTape Trans-obturator Surgical Kit consists of an implantable, suburethral support tape and introducers. It is indicated for the surgical treatment of all types of stress urinary incontinence (SUI), for female urinary incontinence resulting from urethral hypermobility and/or sphincter deficiency.
The Mentor ObTape Trans-obturator Surgical Kit consists of two components: the Mentor ObTape Trans-obturator Tape and a set of Introducer Needles.
The Mentor ObTape Trans-obturator Tape is an implantable, suburethral, support tape indicated for the surgical treatment of all types of stress urinary incontinence (SUI), for female urinary incontinence resulting from urethral hypermobility and/or intrinsic sphincter deficiency. The tape is made from non-woven polypropylene fibers. This structure gives the ObTape resistance to traction, allows tissue colonization and facilitates positioning during surgery.
A set of sterile, disposable Introducer Needles (one flat curved introducer and a pair of helical introducers) necessary for implantation of the tape are also included in the Kit.
The provided text describes a 510(k) submission for the Mentor ObTape™ Trans-obturator Surgical Kit. This is a medical device clearance process, not a study evaluating an AI algorithm, and therefore many of the requested elements (like sample size for test sets, number of experts, MRMC studies, standalone performance of an algorithm, and training set details) are not applicable to this type of regulatory submission.
The "study" in this context refers to the pre-clinical and mechanical testing performed to demonstrate that the device is substantially equivalent to a previously cleared predicate device.
Here's an analysis based on the provided text:

The introducers' performance is based on mechanical and biocompatibility testing against predefined standards, likely conducted by qualified engineers and toxicologists/biologists, but not "experts" establishing a "ground truth" for a test set.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not applicable. No adjudication method is relevant as there is no "test set" or human interpretation of data in the AI context.
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-assisted device.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:
- Not applicable. This is not an AI device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- Not applicable. For the tape, the "ground truth" is that it is identical to a predicate device already deemed safe and effective. For the introducers, the "ground truth" is adherence to established mechanical performance specifications and demonstrated biocompatibility as per relevant standards. These are not "ground truths" in the diagnostic AI sense.
8. The sample size for the training set:
- Not applicable. This is not an AI device with a training set.
9. How the ground truth for the training set was established:
- Not applicable. This is not an AI device.

Mentor ObTape Trans-obturator Tape is an implantable, suburethral, support tape indicated for the surgical treatment of all types of stress urinary incontinence (SUI), for female urinary incontinence resulting from urethral hypermobility and/or intrinsic sphincter deficiency.
ObTape is made from non-woven polypropylene fibers. This structure gives the ObTape resistance to traction, tissue colonization and facilitates positioning during surgery. Disposable and re-usable Introducer Needles necessary for the implantation are also available with the device.
The provided text is a 510(k) summary for a medical device (Mentor ObTape Trans-obturator Tape and Introducers). This type of submission focuses on demonstrating substantial equivalence to a predicate device rather than presenting a standalone study with acceptance criteria and a detailed performance evaluation in the way an AI/software device would.
Therefore, many of the requested categories for a study proving device acceptance against specific criteria are not applicable or cannot be extracted from this document, as it describes a physical surgical mesh and its introducers.
Here's an attempt to answer the questions based on the available information:
Acceptance Criteria and Study to Prove Device Meets Acceptance Criteria
1. A table of acceptance criteria and the reported device performance
| Acceptance Criteria Category | Specific Criteria | Reported Device Performance |
|---|---|---|
| Material Properties | Adherence to established EDANA standards for Tear Strength | Complies with established EDANA standards for Tear Strength |
| Adherence to established EDANA standards for Tensile Strength | Complies with established EDANA standards for Tensile Strength | |
| Adherence to established EDANA standards for Elongation | Complies with established EDANA standards for Elongation | |
| Biocompatibility | Compliance with USP, ISO 10993, or EN standards for Cytotoxicity | Complies with established USP, ISO 10993 or EN standards for Cytotoxicity |
| Compliance with USP, ISO 10993, or EN standards for Genotoxicity | Complies with established USP, ISO 10993 or EN standards for Genotoxicity | |

| Compliance with USP, ISO 10993, or EN standards for Pyrogenicity | Complies with established USP, ISO 10993 or EN standards for Pyrogenicity | |
| Compliance with USP, ISO 10993, or EN standards for Intracutaneous Reactivity | Complies with established USP, ISO 10993 or EN standards for Intracutaneous Reactivity | |
| Compliance with USP, ISO 10993, or EN standards for Sensitization | Complies with established USP, ISO 10993 or EN standards for Sensitization | |
| Compliance with USP, ISO 10993, or EN standards for Systemic Toxicity | Complies with established USP, ISO 10993 or EN standards for Systemic Toxicity |
2. Sample size 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 in the 510(k) summary. The document describes tests against established standards for materials and biocompatibility, but it does not detail the specific sample sizes used for these tests, nor the data provenance in terms of country of origin or whether the tests were retrospective/prospective. This type of detail is typically part of the underlying test reports, not the summary.
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 the type of device and testing described. The "ground truth" for this device is determined by physical and biological testing against recognized industry standards (EDANA, USP, ISO, EN), not by expert interpretation of clinical data in the same way an AI device would require.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This is not applicable to the type of testing described. Adjudication methods are typically used when interpreting subjective data (like medical images), which is not the case for mechanical properties or biocompatibility testing. The compliance is determined by objective measurements against predefined thresholds within the 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 is not applicable. An MRMC study is relevant for evaluating the clinical performance of diagnostic or assistive AI technologies. This submission is for a surgical implant (mesh), not an AI-powered diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This is not applicable. The device is a physical surgical implant, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "ground truth" is based on established industry and regulatory standards for material properties and biocompatibility.
- For mechanical testing: The ground truth for compliance is whether the measured Tear Strength, Tensile Strength, and Elongation meet the specified values within the EDANA standards.
- For biocompatibility: The ground truth for compliance is whether the results of tests for Cytotoxicity, Genotoxicity, Hemolysis, Implantation, Pyrogenicity, Intracutaneous Reactivity, Sensitization, and Systemic Toxicity adhere to the requirements of USP, ISO 10993, or EN standards.
8. The sample size for the training set
This is not applicable. This is a physical medical device, not a machine learning model, so there is no "training set."
9. How the ground truth for the training set was established
This is not applicable. As there is no training set for a physical device, this question is irrelevant.

- UAL patients (test group): 180
- SAL patients (control group): 186
- Data Provenance: The document does not explicitly state the country of origin or whether the data was retrospective or prospective. Given it's a clinical study comparing two treatments for a 510(k) submission, it is highly likely to be a prospective study. The country of origin is not specified, but typically for FDA submissions, studies are often conducted in the US or follow international clinical trial standards.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:
- The document mentions "a masked reviewer" assessed body contour measurements.
- It does not specify the number of experts (beyond "a masked reviewer"), their qualifications (e.g., radiologist with X years of experience), or how they established the 'ground truth' for other measures like satisfaction or self-esteem (which are patient-reported outcomes).
4. Adjudication Method for the Test Set:
- The document does not describe any specific adjudication method (e.g., 2+1, 3+1). For patient-reported outcomes like satisfaction and self-esteem, adjudication is typically not applicable as the patient's report is the primary data. For body contour measurements, "a masked reviewer" implies a single assessment, not a consensus or adjudication process.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
- This study was a clinical comparative effectiveness study, but specifically comparing device performance (UAL vs. SAL lipoplasty), not a multi-reader multi-case study comparing human readers with and without AI assistance.
- Therefore, an effect size of how much human readers improve with AI vs. without AI assistance is not applicable to this document as it's not an AI device.
6. Standalone (Algorithm Only) Performance:
- This is not an AI device, so standalone algorithm performance is not applicable. The study evaluates the performance of a medical device (Mentor® Contour Genesis System) used by a surgeon.
7. Type of Ground Truth Used:
- Primary Safety Measures: Adverse events (patient-reported and/or clinician-observed).
- Secondary Effectiveness Measures:
- Patient-reported overall satisfaction.
- Patient-reported feelings towards each body area treated.
- Patient-reported self-esteem (using Rosenberg Self-Esteem scale and Body Esteem scale).
- Body contour measurements as assessed by a masked reviewer.
8. Sample Size for the Training Set:
- The document describes a clinical study to compare the device, which serves as the test set for demonstrating equivalence. It does not mention a separate training set for the device itself. This device is a physical medical system (ultrasonic generator, handpiece, etc.), not a machine learning algorithm that requires a training set.
9. How Ground Truth for the Training Set Was Established:
- As this is not an AI/ML device, a separate training set and its associated ground truth establishment are not applicable.
