Erco-Ribbon ™ - C is used to maintain penile rigidity in men with erectile dysfunction. It restricts blood outflow from the penis after the patient has obtained an erection (either with the aid of a vacuum pump, or naturally). Men with firm but short lasting erection may use constricting device separately. If a man is impotent to a degree that he is unable to achieve a natural erection, a vacuum constriction system may help him to overcome this dysfunction.

Erco-Ribbon ™ - C can be used for patients with following conditions:

• a) separately:
  premature ejaculation,

firm but short lasting erection.

b) as a part of a vacuum constriction system:

Diabetes

Venous leakage

Prostatectomy

Hypertension

Psychogenic impotence

Impotence due to radiation therapy

Spinal cord injury

Erco-Ribbon ™-C is an improved version of Erco-Ribbon ™, using a cuff for forming a shell around the ribbon and a quick release loop for removing the constrictor. A constriction ribbon is made of elastic and soft rubber-like material with generally rectangular cross section.

For arrangement of Erco-Ribbon ™-C penile constriction device, the ribbon is wrapped with the tension by multyple turns over the proximal end of the mounting tube (or a vacuum chamber, when Erco-Ribbon ™-C is used as a part of a vacuum constriction system). Erco-Ribbon ™-C is locked by the cuff in a state with prearranged inward pressure. A quick release loop unlocks the constrictor and allows easy removal of the ribbon. The materials conform FDA regulation for devices contacting human skin. A mounting tube is made of a segment of acrylic tube.

The provided document is a 510(k) summary for the Erco-Ribbon™ -C, a constriction device for penile rigidity. It focuses on demonstrating substantial equivalence to existing predicate devices rather than directly presenting a study with specific acceptance criteria and detailed performance metrics as would be typical for a device providing diagnostic or treatment efficacy data.

Therefore, the information regarding acceptance criteria and a study proving their fulfillment is largely not present in the provided text in the traditional sense you might expect for a diagnostic AI device or certain therapeutic devices. The submission focuses on design and material comparisons to established equivalent devices.

However, I will extract what can be inferred as "acceptance criteria" based on the comparison made and the overarching goal of a 510(k) submission, and then describe how the comparison itself serves as the "study" for showing substantial equivalence.

Here's the breakdown based on your request:

Acceptance Criteria and Study Proving Device Meets Acceptance Criteria

The Erco-Ribbon™ -C is a constriction device for penile rigidity that was submitted for 510(k) clearance, asserting substantial equivalence to predicate devices already on the market. In such a submission, "acceptance criteria" are implicitly tied to demonstrating that the new device is as safe and effective as the predicate devices, despite technological differences. The "study" proving this is primarily a comparative analysis of design, materials, and intended use, rather than a clinical trial with statistical endpoints against pre-defined performance metrics.

1. A table of acceptance criteria and the reported device performance

Given the nature of this 510(k) submission, the "acceptance criteria" are derived from the safety and performance characteristics of the predicate devices. The "reported device performance" is a comparative qualitative assessment rather than quantitative measurements from a specific trial.

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 document. The submission does not describe a clinical "test set" with patients. The "test" in this context is the qualitative comparison of design and functionality against predicate devices.

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 information is not provided. As no clinical "test set" or diagnostic ground truth was established, no experts in this capacity were involved in the described comparison. The "ground truth" for the submission is the established safety and effectiveness of the predicate devices based on their long-term marketing.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

This information is not provided, as there was no test set requiring expert adjudication.

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

An MRMC comparative effectiveness study was not performed. This type of study is relevant for diagnostic devices often involving image interpretation or clinical decision support, which is not the function of the Erco-Ribbon™ -C. This device is a mechanical constriction aid.

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

A standalone performance study was not performed in the traditional sense of an algorithm. The device's "standalone performance" is its mechanical function, which is assessed through a comparative description rather than quantitative testing data in this submission.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

The "ground truth" for this 510(k) submission is the established long-term safety and effectiveness of the legally marketed predicate devices to which the Erco-Ribbon™ -C claims substantial equivalence. The argument is that if the new device is sufficiently similar in intended use and fundamental operating principle, and its technological differences lead to superior or at least equivalent safety and performance, then it is substantially equivalent.

8. The sample size for the training set

This information is not provided. There was no "training set" in the context of device development described in this submission, as it's a mechanical device, not an AI algorithm.

9. How the ground truth for the training set was established

This information is not provided, as there was no training set.

Summary of the "Study" (Substantial Equivalence Comparison):

The "study" presented in this 510(k) is a documentary comparison (a "Comparison of design and performance") between the Erco-Ribbon™ -C and several legally marketed predicate devices (ErecAid, Confidence, VED, VET, Pos-T-Vac, and the previous Erco-Ribbon™).

The comparison highlights technological differences of the Erco-Ribbon™ -C (e.g., multi-turn ribbon design, quick release loop, cuff for shell formation) and argues how these differences provide superior safety and performance compared to the predicate's fixed-size, molded constriction rings. Key arguments for superior safety and performance included:

• User-adjustable pressure: Allows for smooth control of pressure, reducing instances of excessive pressure and discomfort.
• Easier application: Multi-turn ribbon is easier to apply than solid rings, requiring less force to extend.
• Easier removal: Quick release loop allows for easy removal.
• Reduced discomfort/pain: Less twisting/intertwining with pubic hair, and less pain during removal.
• Material conformity: Materials meet FDA regulations for skin contact.

The conclusion is that despite technological differences, the Erco-Ribbon™ -C has the same intended use as the predicate devices and its design features lead to superior safety and performance, thus establishing substantial equivalence.

1. A table of acceptance criteria and the reported device performance: This information is completely absent. The document states a claim of "superior safety and performance" compared to predicate devices, but no metrics or specific criteria are provided.
2. Sample sized used for the test set and the data provenance: There is no mention of any test set, sample sizes, or data provenance (e.g., country of origin, retrospective/prospective).
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: There is no mention of ground truth or experts for performance evaluation.
4. Adjudication method for the test set: No test set or adjudication method is described.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and the effect size: No such study is mentioned.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: As this is a physical medical device, not an algorithm, this question is not applicable in the context of the provided document. Even if rephrased for device performance, no standalone performance study details are given.
7. The type of ground truth used: No ground truth is discussed in relation to a performance study.
8. The sample size for the training set: There is no mention of a "training set" as this is not an AI/ML device and no performance study details are given.
9. How the ground truth for the training set was established: Not applicable, as there is no training set mentioned.

What the document does provide in relation to general performance and comparison:

• Claim of Superiority: "Technological differences of Erco-Ribbon™ provide superior safety and performance." This is a general claim, not supported by quantitative data in this summary.
• Comparison to Predicate Devices: The document extensively compares the Erco-Ribbon™ to predicate devices based on design and perceived user experience (e.g., ease of application, comfort, pressure control, removal). It highlights potential issues with predicate devices (excessive pressure, discomfort, difficult placement, painful removal) and suggests that the Erco-Ribbon's design (multi-turn ribbon, user-adjustable tension) addresses these. These are qualitative comparisons based on design features, not quantitative performance metrics from a study.
• Material Conformance: "The material conforms FDA regulation for devices contacting human skin." This is a regulatory conformance statement, not a performance metric from a study.

In summary, the provided 510(k) summary focuses on demonstrating substantial equivalence based on intended use and design characteristics, arguing for improved user experience and safety. It lacks the specific performance data and study details requested in your prompt.
