ATHENA PELVIC MUSCLE TRAINER
The Athena Pelvic Muscle Trainer is intended to provide electrical stimulation and neuromuscular reeducation for the purpose of rehabilitation of weak pelvic floor muscles for the treatment of stress, urge and mixed urinary incontinence in women.
The Athena Pelvic Muscle Trainer is a vaginal two electrode stimulation probe operated through a FM remote control device. The probe is stored in an activator box that turns the probe on automatically when the probe is removed from the box.
The provided text is a 510(k) Premarket Notification for the Athena Pelvic Muscle Trainer. It focuses on demonstrating substantial equivalence to existing predicate devices, rather than presenting a standalone study with acceptance criteria and detailed performance metrics of the device itself. Therefore, many of the requested details about a study and its results cannot be fully extracted.
Here's an analysis based on the provided text, addressing the points where information is available and indicating where it is not:
1. A table of acceptance criteria and the reported device performance
The document does not explicitly define "acceptance criteria" in the context of a performance study for the Athena Pelvic Muscle Trainer. Instead, it compares the device's technical specifications to those of legally marketed predicate devices to establish substantial equivalence.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document does not describe a clinical performance study with a test set. This 510(k) is based on demonstrating substantial equivalence through comparison of technical specifications and intended use to predicate devices. No patient data or clinical study results for the Athena Pelvic Muscle Trainer are provided.
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)
Not applicable, as no clinical performance study involving a test set and ground truth establishment is described.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable, as no clinical performance study involving a test set is described.
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 device is an electrical stimulator, not an AI-powered diagnostic tool, and no MRMC study is mentioned.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Not applicable. This device is an electrical stimulator, not an algorithm, and its performance is assessed against predicate devices' technical specifications, not by an algorithm's standalone performance.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
Not applicable, as no clinical performance study with defined ground truth is described. The "ground truth" in this context is the established safety and effectiveness of the predicate devices based on their prior clearance, to which the new device claims substantial equivalence.
8. The sample size for the training set
Not applicable, as no AI model or training set is mentioned for this device.
9. How the ground truth for the training set was established
Not applicable, as no AI model or training set is mentioned for this device.
