AI/ML Overview

The provided text describes a 510(k) premarket notification for a medical device, specifically SPROTTE® STANDARD (LUER/ NRFit®) Anesthesiology needles. The submission aims to demonstrate substantial equivalence to a legally marketed predicate device (SPROTTE NRFit™, Quincke NRFit™) by validating the addition of an alternative sterilization service provider and an alternative packaging material.

The document does not detail acceptance criteria or study results for AI performance or diagnostic accuracy. Instead, it focuses on the physical and biological characteristics of the needle itself, and the validation of manufacturing processes (sterilization and packaging) to ensure sterility and shelf life.

Therefore, many of the requested items (e.g., AI performance, expert ground truth, MRMC studies, training set details) are not applicable to this type of device submission. This is a traditional medical device submission, not an AI/ML-based device.

However, based on the provided text, we can address the applicable criteria:

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

The acceptance criteria are generally implied by adherence to relevant ISO standards and maintaining the same performance characteristics as the predicate device. The "reported device performance" is essentially a "Pass/Fail" determination against these standards.

ISO 80369-7 (LUER Connectors)
7.1 Fluid Leakage	Passed
7.2 Air Leakage	Passed
7.3 Stress Cracking	Passed
7.4 Separation Axial Load	Passed
7.5 Unscrewing	Passed
7.6 Overriding	Passed
Sterilization (ISO 11135-1)
Sterility Assurance Level (SAL)	SAL=10^-6 (Validated)
EO and ECH Residuals (ISO 10993-7)	Compliant
Shelf Life

No decrease in performance after 60 months	Validated
Biocompatibility (ISO 10993-1)	Compliant
Use of materials	Compliant

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):

Sample Size: The document indicates that for ISO 9626, "5.7 Sample size" was "Passed", implying a specific sample size was used as per the standard, but the exact number is not provided. For sterility and shelf-life testing, "process most challenging worst case devices" were used, but specific numbers are not given.
Data Provenance: The manufacturing and testing are stated to occur at PAJUNK GmbH Medizintechnologie in Geisingen, Germany, and the contract sterilizers are in Wiesbaden, Germany (Sterigenics) and Halberstadt, Germany (HA2 Medizintechnik). The data is derived from prospective testing conducted to validate the manufacturing and sterilization processes.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

This is not applicable. This submission concerns the physical and biological characteristics of a medical device (anesthesia needle) and the validation of its manufacturing and sterilization processes, not the performance of an AI/ML algorithm or diagnostic accuracy involving expert review.

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

This is not applicable. No adjudication method for expert reviews or ground truth establishment is mentioned as this is not an AI/ML or diagnostic performance study. Performance is measured against specific ISO standards and validated processes.

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. This is not an AI-assisted device; it is a physical medical device.

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

This is not applicable. This is not an AI/ML algorithm.

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

The "ground truth" in this context is the adherence to established international standards (ISO series) for medical device design, manufacturing, sterilization, and biocompatibility. For instance, sterility is validated to an SAL of 10^-6 (a defined standard), and material properties are tested against specified values in the ISO standards. The performance characteristics of the new device are directly compared to existing predicate devices and their proven specifications, and confirmed by testing against the same engineering and safety standards.

8. The sample size for the training set:

This is not applicable. This is not an AI/ML device that requires a training set.

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

This is not applicable.

4 Substantial Equivalence Discussion

The subject device can be either directly injection moulded or glued. The predicate device technology for hubto-needle bonding is glueing. Both manufacturing technologies are safe and the processes are running stable. Both technologies - direct molding as well as glueing - are standard technologies.

Also the connectivity of the subject device can be eigther LUER or NRFit. The connectivity of the predicate device is NRFit. Both connectivities - LUER as well as NRFit - are state of the art.

The predicate devices, the Sprotte NRFit and Quincke NRFit needles, are packed with Tyvek and foil and sterilized with Ethyleneoxide at Sterigenics, Germany.

The subject devices, the Sprotte STANDARD (LUER/ NRFit) needles, are packed either with Tyvek and foil as well as optionally with Medical Paper and foil.

Furthermore, the subject devices are sterilized at Sterigenics in Wiesbaden as well as optionally at HA2 Medizintechnik in Halberstadt.

The main differences which are subject to this premarket submission are

the addition of a sterilization facility and a)
b) the addition of an alternative packaging material.

In order to verify substantial equivalence of the sterilization validation validation according ISO11135 has been performed and successfully accomplished. The sterility assurance level of 10-6 has been successfully validated at both facilities: Sterigenics and HA2.

In order to verify substantial equivalence of the packaging and shelf life tests have been

The needles subject to this premarket submission are subject to performance testing prior to release as well as after shelf life scenario of 5 years.

There is no impact of the change subject to this submission (additional optional sterilization provider, additional optional packaging) on the performance of the needle as defined in the user requirements specification.

Especially the hub to needle bonding requirements remain unaffacted. The processes are still valid and reliable.

6 Sterilization

The contract sterilizer and the sterilizing process are identical to the process and sterilizer used for all PAJUNK® - manufactured devices which are already cleared for market or exempt.

Sterilization parameters are:

SAL	10-6
Type of gas	Ethylene Oxide 99,99%

Sterilization has been validated according to ISO 11135-1 Overkill Approach (1 sublethal cycle, 2 half cycle, 1 full cycle)

Residuals of EO and ECH are in compliance with ISO 10993-7.

Cleaning and Sterilization method, which ensures an SAL of 10-6 as well as compliance with limits for chemical burden, bioburden, pyroburden (i.e. LAL) and EtO-residuals as well as shelf life have been validated and are safe and effective.

The limits listed below are met by each device:

Limits for Residuals: 25ppm = 25μg/(g/device) of Ehyleneoxide (EO); 25ppm = 25μg/(g/device) Ethylene chlorhydrine

7 Shelf Life

Efficiancy of sterile product's lifecycle has been validated using process most challenging worst case devices.

Sterility tests have been performed using process most challenging worst case devices with similar characteristics made from the same material after 5 years. The devices were found to be sterile after 5 years, the sterile barrier system is efficient.

Performance of the device (LUER/ NRFit connection, stability of bonding connections, needle s bending rigidity) has been tested. There is no decrease in performance after 5 years. Shelf-life is set to 5 years.

8 Biocompatibility

All products comply with ISO 10993-1 and with FDA´s guidance Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process".

Therefore, based on sterilization and residuals validation the kits also are considered to be biocompatible.

9 Technology Characteristics

Both, the subject device and the predicate device, consist of identical components.

10 Conclusion

The comparison between the predicate device and the subject device of this submission focussed on the validated sterilization process and the shelf life testing demonstrates that the subject device can be optionally in addition packed using medical paper and can be optionally sterilized at the alternative sterilization service provider at an SAL of 10-6.

The results demonstrate that the subject device is substantially equivalent and as safe, as effective, and performs as well as the predicate device.
