The 510(k) summary describes a physical medical device (needles) and does not mention any software, algorithms, or data processing that would indicate the use of AI or ML.
No.
The device is a needle intended for the transient delivery of anesthetics or to facilitate epidural catheter placement, not for therapeutic treatment itself.
No
The device is described as an anesthesia needle for the delivery of anesthetics and placement of epidural catheters, not for diagnosing conditions.
No
The device description clearly describes physical needles and optional accessories made from plastic or stainless steel, indicating it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the "transient delivery of anesthetics to provide regional anesthesia and analgesia or to facilitate placement of an epidural catheter." This is a direct medical intervention on a patient, not a test performed on a sample taken from the body to diagnose a condition.
- Device Description: The device is a "Tuohy NRFit™ cannulas/ needles for anesthesia." This is a physical instrument used for delivering substances or placing catheters within the body.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting analytes, or providing diagnostic information based on laboratory testing.
IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This device's function is purely procedural and therapeutic (delivering anesthetics or facilitating catheter placement).

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
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
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

Both, the subject devices as well as the predicate devices have been tested ready to use right after sterilization and have been subject to testing after accelerated aging (1year, 3years, 5years) in order to demonstrate substantial equivalence and Shelf Life.
8
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.
Sterilization parameters are
| SAL | 10-6 |
|---|---|
| Type of gas | Ethylene Oxide 99,99% |
| Exposure time | 300 min. |
| Aeration method | evacuation |
| 2 airwashes | |
| Aeration period | residual EtO-gas is removed in circulating |
| air at 40° C (±5) for at least 48h |
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° as well as compliance with limits for chemical burden, bioburden (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:
Limits for Residuals: 25ppm = 25μg(g/device) of Ethyleneoxide (EO); 25ppm = 25μg/(g/device) Ethylene chlorhydrine
Limit for Pyroburden/ endotoxine: 0,06 EU/ml and 2,15 EU/ device acc. to FDA GUIDELINE ON VALIDATION OF LIMULUS AMEBOCYTE LYSATE TEST AS AN END-PRODUCT ENDOTOXIN TEST FOR HUMAN AND ANIMAL PARENTERAL DRUGS, BIOLOGICAL PRODUCTS, AND MEDICAL DEVICES - Issued 12/ 1987
The needles are also available in bulk non sterile. If appropriately packed and sterilized with Ethylene oxide 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.
9
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 aqed 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 years.
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.
Shelf-life is set to 5 years (60 month).

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 because the materials used as well as the processes employed (glue or/and direct injection moulding) remain unaltered. Therefore the biocompatibility testing conducted with the predicate device is still valid.
All devices comply with ISO 10993-1, 2nd and 3rd edition.
