The device is intended for adult and pediatric patients.
The SPROTTE® Special NRFit™ anaesthesia conduction needle is intended to gain entry into the spinal canal to apply single shot spinal anaesthesia. It has an opening which will allow the introduction of a catheter which is used to inject anaesthetics to provide continuous spinal anaesthesia. The device is available in a range from 18G to 24G at a range of length from 90mm to 100mm. It is a disposable device, supplied sterile to the end user and non-sterile intended to be sterilized prior to use to repackagers/medical device manufacturers. The materials used include Stainless Steel 1.4301 (X5CrNi18-10), AISI 304 (V2A) for the needle/cannula, introducer tubing, stylet tubing, and haemostylet. Polycarbonate PC is used for the needle hub, ramp in tip, introducer hub, stylet knob, and retaining plate. Epoxy resin is used for optional glue.
This document describes the 510(k) premarket notification for the PAJUNK® SPROTTE® Special NRFit™ anesthesia conduction needle. The submission aims to demonstrate substantial equivalence to a predicate device (K911221 ATRAUMATIC SPECIAL SPROTTE NEEDLE). The key differences highlighted are the material of the hub and the stylet's knob, which are deemed non-significant due to either historical changes with new material being tested, or no patient contact for the knob.
Here's an analysis of the provided information, structured according to your request:
1. Table of Acceptance Criteria and Reported Device Performance
| Test/Criterion | Acceptance Criteria | Reported Device Performance |
|---|---|---|
| Bending Rigidity (Needle) | Compliant with ISO/FDIS 9626:2016 | The bending rigidity of both predicate and subject device needles is compliant with the standard. |
| Bonding to Hub (Needle) | Pull-off force ≥ 22N (per ISO/FDIS 7864:2016) | A force significantly higher than 22N had to be applied for both subject and predicate device needles. |
| Penetration Force (Needle) | No normative pass/fail criteria; objective comparison for less trauma (per ISO/FDIS 7864:2016 guidance) | Subject and predicate device needles show identical penetration/insertion forces. |
| Sterility Assurance Level (SAL) | 10-6 | Achieved 10-6 SAL. |
| EO and ECH Residuals | Compliant with ISO 10993-7 | In compliance. |
| Biocompatibility | Compliance with ISO 10993-1 (2nd and 3rd edition) and successful completion of specified tests. | Successfully completed tests: In vitro Cytotoxicity, Irritation, Sensitization, Acute systemic toxicity, Hemocompatibility. All devices comply. |
| Shelf-Life | 5 years, with continued efficacy of sterile barrier and essential performance. | Devices were found sterile after 5 years, sterile barrier efficient. No decrease in essential performance (connection, bonding, tensile strength, rigidity) after 5 years. |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set:
- For the subject devices, 5 types of SPROTTE® Special NRFit™ needles were tested, ranging from 18G to 24G in gauge and 90mm to 100mm in length.
- For the predicate devices, 5 types of SPROTTE® Special needles were tested, with the same range of gauge and length.
- Each of these device types was tested after sterilization and after accelerated aging (1 year, 3 years, 5 years). The specific number of individual units tested per type is not explicitly stated beyond these categorical breakdowns.
- Data Provenance: The document does not explicitly state the country of origin for the data or whether it was retrospective or prospective. Given that the manufacturer is a German company (PAJUNK® GmbH Medizintechnologie) and the studies involve physical testing of medical devices, the data is likely generated in a laboratory setting, presumably by or on behalf of the manufacturer, and would be considered prospective for the purpose of this submission.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications
This submission does not involve clinical studies with human "ground truth" derived from expert consensus. The "ground truth" or acceptance criteria are based on recognized international standards for medical devices (e.g., ISO 9626, ISO 7864, ISO 80369-6, ISO 11135-1, ISO 10993-1/5/10), which define physical and material properties, performance characteristics, and safety aspects. Therefore, no human experts were used to establish "ground truth" in the diagnostic sense.
4. Adjudication Method for the Test Set
Not applicable. This is not a study requiring adjudication of diagnostic outcomes. Performance is measured against engineering and safety standards.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
Not applicable. This is a premarket notification for a physical medical device (anesthesia conduction needle), not an AI-assisted diagnostic tool. Therefore, no MRMC study or assessment of human reader improvement with AI assistance was conducted.
6. Standalone Performance Study (Algorithm Only)
Not applicable. This device does not involve an algorithm.
7. Type of Ground Truth Used
The ground truth used for performance and safety assessments is primarily engineering and safety standards (e.g., ISO 9626, ISO 7864, ISO 80369-6, ISO 11135-1, ISO 10993-1/5/10) and the physical and material characteristics of the predicate device. For tests like bonding strength and bending rigidity, the "ground truth" is adherence to predefined force thresholds or established methodologies in the standards. For biocompatibility, it's compliance with ISO standards through a series of conducted tests.
8. Sample Size for the Training Set
Not applicable. There is no "training set" in the context of an AI/algorithm. The "training" for this device's performance comes from historical data, design validation, and manufacturing processes perfected over time, as implied by the use of an already cleared predicate device.
9. How the Ground Truth for the Training Set was Established
Not applicable, as there is no training set. The "ground truth" for the device's design and manufacturing is established through compliance with established medical device regulations, design controls, and international standards. The substantial equivalence argument relies on the predicate device's established safety and effectiveness.

12.2.2.1.1 Discussion of differences
-
The material of the hub has been altered in 1994. Before that date Polycarbonate PC xxx has been used which then was switched to Polycarbonate PC - yyy. The biocompatibility test reports provided for the SPROTTE contain needles equipped with hubs made from yyy. However, the base substance for both is Polycarbonate Medical Grade. xxx has a significant higher flow pattern index.
-
The material of the stylet´s knob has been switched from Poliamide zzz to Polycarbonate PC yyy. Since the knob does not have any patient contact this change is non-significant to form, fit and function.
12.2.2.3 Devices under test
For demonstrating substantial equivalence the items listed below have been compared:

12.2.3 Technology/ Performance
12.2.3.1 Performance Testing: Summary
The predicate device as well as the subject device only differs in design of the hub.
This difference does not have any impact on the performance tests listed below. Therefore performance testing is still valid and applies to both, subject device and predicate device.
The performance tests have been accomplished in order to comply with the standards listed below (even though 6-366 and 6-362 are not directly linked with Product Code BSP):
| Recognition-# | Standard Number | Title |
|---|---|---|
| 6-366 | ISO 9626 | Stainless steel needle tubing for the manufacture ofmedical devices - Requirements and test methods |
| 6-362 | ISO 7864 | Sterile hypodermic needles for single use -Requirements and test methods |
| 5-108 | ISO 80369-6 | Small bore connectors for liquids and gases inhealthcare applications - Part 6: Connectors forneuraxial applications. |
Stability test Bonding-to-Hub has to be conducted in order to compare the stability of the LUER Hub with the stability of the NRFit™ hub.
Furthermore compliance of the needle hub with ISO 80369-6 has to be proven.
Standard testing regarding the remaining sections of the recognized performance standards can be conducted using either the predicate device or the subject device because the needle tubing is absolutely identical.
Needle: stability test bending rigidity
Reason for test: The needle has to demonstrate bending stability and resistance against breakage in order to resist forces reasonably assumed to the needle in situ under the defined intended use
Procedure of test: The test procedure is defined by international standard ISO/FDIS 9626:2016 Stainless steel needle tubing for manufacture of medical devices.
Pass/ Fail criteria: The acceptance criterion of bending rigidity for the cannula is defined in above mentioned standard.
Results: The bending rigidity of the predicate device 's needles and the subject device's needles is compliant with the standard.
Conclusion: Substantially Equivalent
{9}------------------------------------------------
Needle: stability test bonding to hub
Reason for test: The needle has to demonstrate stability at the bonding of the hub in order to resist forces reasonably assumed to be applied to the needle in situ under the defined intended use.
Procedure of test: The test procedure is defined by international standard ISO/FDIS 7864:2016 Sterile hypodermic needles for single use
Pass/ Fail criteria: The acceptance criterion for the bond between hub and needle tube (pull-off force) is ≥22N.
Results: For the needles of the subject device and the needles of the predicate device a force significantly higher than the target value has to be applied. Therefore the predicate device 's needles as well as the subject device 's needles are substantially equivalent.
Conclusion: Substantially Equivalent
Needle: Penetration force
Reason for test: The needles have to demonstrate less trauma when applied with the patient under the intended use. ISO/FDIS 7864:2016 Sterile hypodermic needles for single use recommends penetration force testing only without giving a normative test method.
Procedure of test: According to international European standard EN 13097.
Pass/ Fail criteria: -none- objective comparison only.
Results: The subject device's needles as well as the predicate device´s needles show identical penetration/ insertion forces.
Conclusion: Substantially Equivalent
2.4 Sterilization
The predicate device as well as the subject device only differs in design of the hub. This difference does not have any impact on Sterilization. Therefore the Sterilization is still valid.
The contract sterilizer and the sterilizing process are identical to the contract sterilizer and the sterilizing process used for all PAJUNK® - manufactured devices which are already cleared for market or exempt.

Pioneering medical technology
Cleaning and Sterilization method, which ensures an SAL of 10th as compliance with limits for chemical burden, bioburden, pyroburden (i.e. LAL and the rabbit pyrogen test) and EtOresiduals as well as shelf life have been validated.
The limits listed below are met by each device:
The needles are also available in bulk non sterile. If appropriately packed and sterilized with Ethyleneoxide according to the parameters above the technological parameters remain unchanged. However, final responsibility for sterilization remains with the customer of needles purchased bulk non-sterile.
2.5 Shelf Life
The predicate device as well as the subject device only differs in design of the hub. This difference does not have any impact on Shelf Life. Therefore the Shelf Life is still valid.
Efficacy of sterile product's lifecycle has been validated using similar products and worst case devices.
Sterility tests have been performed using worst case devices with similar characteristics made from identical material after 5 years. The devices were found to be sterile after 5 years, the sterile barrier system is efficient.
Performance of the essential performance of the device (LUER/ NRFit™ connection, stability of bonding connections, catheter's tensile strength, needle 's bending rigidity) has been tested with real time aged needles and catheters made from identical material employing identical processes and those are found to work properly. There is no decrease in performance after 5 vears.
Shelf-life is set to 5 years.
2.6 Biocompatibility:
The predicate device as well as the subject device only differs in design of the hub. The manufacturing processes of the subject device and the predicate device are identical. The difference in design does not have any impact on Biocompatibility of the device. Therefore the biocompatibility testing conducted with the predicate device is still valid.
All devices comply with ISO 10993-1, 2nd and 3rd edition.
The tests listed below have been conducted and accomplished successfully by the worst case device:
- . In vitro Cytotoxicity ISO 10993-5
- . Irritation ISO 10993-10
- Sensitization ISO 10993-10
- Acute systemic toxicity
- . Hemocompatibility
Therefore and based upon sterilization validation and residuals validation the devices are considered to be biocompatible.
