Peritron is used in assessing the strength of pelvic floor muscles, teaching pelvic floor muscle exercises and for providing feedback during pelvic floor muscles exercises.
The Peritron Perineometer comprises a vaginal or anal Sensor, Readout Unit and interconnecting tube. Peritron incorporates a pressure transducer and microprocessor to interpret the air pressure in the sensor and display it either numerically in cm water column pressure or as an analogue bar graph. Hand-held Peritron weighs 220 gm and is powered by a standard 9 volt battery housed in an integral, user-accessible compartment separated physically from the electronic components. All operating functions are controlled by one push-button. The case of Peritron is of injection moulded plastic.
I am sorry, but the provided text does not contain the acceptance criteria or a study that proves the device meets specific acceptance criteria in the format requested.
The document is a "Safety and Effectiveness Summary" for the Peritron Perineometer (K983052), which aims to demonstrate substantial equivalence to a predicate device (Contimed II™) for FDA clearance. It discusses the device's design, safety features, and a general statement about manufacturing compliance.
Here's what I can extract and what's missing based on your request:
What's available in the text:
- Device Description: The Peritron Perineometer is described as comprising a vaginal or anal Sensor, Readout Unit, and interconnecting tube, used for diagnosing and treating stress incontinence, assessing pelvic floor muscle strength, and providing exercise feedback.
- Substantial Equivalence Claim: The document explicitly states, "Peritron does not alter the effectiveness compared to substantially equivalent Contimed II™ device as both devices measure the increase in air pressure in a sensor caused by a voluntary contraction of pelvic floor muscles."
- Manufacturing Compliance: "Peritron is tested during manufacture for compliance with the performance criteria set out in the Brochure and Handbook of Appendix five." (However, "Appendix five" and the specific performance criteria are not provided).
- Safety Experience: "Since its inception in 1991, over 1200 units have been put into operation and at no time during the development or usage of the Peritron has there been an incident that in any way threatened the safety of any individual." This is a general safety statement, not a performance study.
- FDA Clearance: The letter from the FDA confirms the device is "substantially equivalent" to legally marketed devices based on the submitted 510(k) notification.
Missing Information (which is what you requested):
- Table of acceptance criteria and reported device performance: This is not present. The document mentions "performance criteria set out in the Brochure and Handbook of Appendix five," but these criteria and the specific test results against them are not included.
- Sample size used for the test set and the data provenance: Not mentioned.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not mentioned.
- Adjudication method for the test set: Not mentioned.
- Multi Reader Multi Case (MRMC) comparative effectiveness study: No such study is described. The document relies on substantial equivalence to a predicate device's general effectiveness.
- Standalone (i.e., algorithm only without human-in-the-loop performance) study: Not applicable as this is a physical device that measures a physiological action, not an algorithm.
- Type of ground truth used: Not explicitly defined in terms of a study comparing device measurements to a gold standard. The device measures pressure from voluntary muscle contraction, implying real-time physiological response.
- Sample size for the training set: Not applicable as this is not an AI/machine learning device that requires a training set.
- How the ground truth for the training set was established: Not applicable.
In summary, this document is a regulatory submission for premarket clearance based on substantial equivalence, focusing on safety and general effectiveness relative to an existing device. It does not provide the detailed performance study data, acceptance criteria, or ground truth methodologies typically found in a clinical validation study for a new device's specific performance metrics.

Safety and Effectiveness Summary
This summary of safety and effectiveness information is being submitted in accordance with the requirements of SMDA 1990.
Background:
The Peritron Perineometer comprises a vaginal or anal Sensor, Readout Unit and interconnecting tube.
Perineometers are used in the diagnosis and treatment of stress incontinence in patients and for providing exercise feedback.
In the clinic Peritron is used to assess the condition of the pelvic floor muscles, (strength of contraction), teach pelvic floor exercises with the view to improving muscle strength and may be used at home as a biofeedback unit by patients performing pelvic floor exercises.
In operation, air displaced from the sensor caused by a voluntary contraction of the muscles of the pelvic floor travel to the readout units via the interconnecting tube. Peritron does not cause the contraction. These muscles are under the voluntary control of the user at all times.
1 Safety
None of these products diminish the safety level set by the substantially equivalent Contimed II™ (Hollister, Illinois) of Appendix 4(a) due to the following
1.1 Sensors
ﻣﻌﺘﺴﺴﺴﺴﺴﺴﺴﺴﺴﺴﺴﺴ
The key element concerning patient/user safety and the only contact component is the sensor.
As a principal manufacturer of catheters and tubing packs for Cardiac Surgery (Registered in Australia under the Therapeutic Goods Act as a GMP manufacturer but with no goods registered or offered for sale in the USA) we believe we have a good understanding of appropriate materials and manufacturing procedures necessary to produce a product of the highest biocompatibility and patient safety.
Accordingly we designed the sheath of the sensor (the only patient-contact surface) to be moulded in one piece without joins or crevices to potentially harbour bacteria. (In this respect it is safer than the vaginal sensor of the substantially equivalent Contimed unit, the several elements of which join together on the patient contact surface.) The sheath is injection moulded from liquid silicon rubber, Wacker Elastosil cat LR 3003/50A and LR/50B, that meets the requirements of FDA regulation 177.2600. Refer to documents in appendix 6(a)
As the sheath of the sensor contains 600ppm of blue pigment (Wacker cat RAL 5010 ref enclosure 6(c)) of unknown biocompatibility the FDA previously advised that we should conduct testing of the finished product. Refer to appendix 6 (a) for the test results.
{1}------------------------------------------------
1.2 Readout Unit
Peritron incorporates a pressure transducer and microprocessor to interpret the air pressure in the sensor and display it either numerically in cm water column pressure or as an analogue bar graph.
Hand-held Peritron weighs 220 gm and is powered by a standard 9 volt battery housed in an integral, user-accessible compartment separated physically from the electronic components.
All operating functions are controlled by one push-button.
The case of Peritron is of injection moulded plastic. There are no external parts that are of metal or are sharp and no electronic parts are accessible without the use of a tool.
At the time of the previous 510(k) application we understand electrical testing of the device was not required. However, since the previous approval we have had Peritron tested for Emission and Safety. The testing shows that Peritron is safe for the intended use. Refer to appendix 6(b) for test results.
1.3 Summary of Safety Features of Peritron
-
- Peritron is a passive device - it measures the result of a voluntary action of the user.
-
- There are no external wires, electrodes or electrical items of any kind.
-
- Internal user adjustments are neither required nor possible.
-
- A PVC tube is the only connection between the vaginal probe of the patient/user and the Readout unit.
-
- There are no liquids or dangerous items incorporated.
-
- All tests show that Peritron is safe for the intended use and meets standards where they exist.
Safety Experience
Since its inception in 1991, over 1200 units have been put into operation and at no time during the development or usage of the Peritron has there been an incident that in any way threatened the safety of any individual.
Effectiveness 2.
Peritron does not alter the effectiveness compared to substantially equivalent Contimed II™ device as both devices measure the increase in air pressure in a sensor caused by a voluntary contraction of pelvic floor muscles.
Like Peritron, Contimed 11 conveys air from its sensor to the readout unit by means of a plastic tube.
Peritron is tested during manufacture for compliance with the performance criteria set out in the Brochure and Handbook of Appendix five. We would be pleased to make test results available on request.
