Substantial Equivalence Discussion

• There are no differences in intended use and indications for use between the subject device and the predicate device.

• Subject device has different materials of construction in its hub and adhesive. Biological evaluation has been performed in accordance with ISO 10993-1:2018 to demonstrate the material differences do not raise new or different questions of safety and effectiveness as compared to the predicate device.

• Subject device has a different hub and cannula design. The subject device has both a 27G and 29G cannula model compared to the predicate device with includes a 27G and 30G cannula. In addition, the cannula of the subject device has a 45° back-end cut, whereas the cannula of the predicate device has a straight back-end cut. The 45° back-end cut helps in ensuring an easy fluid passage and a homogenous flow. Design verification has been evaluated according to ISO 7864:2016, ISO 9626:2016 and ISO 80369-7:2021. The same standards were utilized for the predicate device to demonstrate performance. Hence, the differences in technological characteristics of the subject device compared to the predicate do not raise new or different questions of safety and effectiveness.

8. Non Clinical Test (807.92(b)(1))

Performance

The design of the K-Pack Enhance Needle has been validated by Terumo Europe N.V. in accordance with the Design Control Requirements and recognized consensus standards that have been established for hypodermic needles under FDA product code FMI and 21CFR Section 880.5570:

  • ISO 7864:2016 "Sterile hypodermic needle for Single use"
  • ISO 9626:2016 "Stainless steel needle tubing for the manufacturing of medical devices"
  • ISO 80369-7: 2021 "Small bore connectors for liquids & gases in healthcare applications – Part 7: Connectors for intravascular or hypodermic applications
  • ISO 6009:2016 "Hypodermic needles for single use — Colour coding for identification"
  • ISO 11607-1:2019 "Packaging for terminally sterilized medical devices - Part 1: Requirements for materials, sterile barrier systems and packaging systems"
  • USP <788> Particulate matter in injections
  • USP <71> Sterility test

Biocompatibility

The K-Pack Enhance Needles are categorized following the definitions in ISO 10993-1:2018 as external communicating devices that can contact tissue or that can indirectly contact the blood path up to 24 hours (limited exposure).

Page 14

The biological evaluation for the K-Pack Enhance Needle has been performed taking into consideration the materials of construction and manufacturing process. The raw materials used for the manufacturing of the K-Pack Enhance Needle were carefully selected and consequently the chosen materials are suitable to be used for production of this product for human use. The raw materials comply with the required internal specifications (with reference to standards and/or guidance if applicable) and applicable legislation and have passed all necessary tests during incoming inspection.

Moreover, considering FDA Guidance document: Use of International Standard ISO-10993-1, "Biological Evaluation of Medical Devices Part-1: Evaluation and testing within a risk management process" the following biological endpoints are addressed: cytotoxicity, sensitization, intracutaneous reactivity, acute systemic toxicity, material-mediated pyrogenicity, and hemolysis.

Sterilization and shelf life

The sterility of the K-Pack Enhance Needle is assured by using a validated sterilization method qualified in accordance with ISO 11135:2014 "Sterilization of Health Care Products – Ethylene oxide – Part 1: Requirements for the development, validation and routine control of a sterilization process for medical devices" to ensure that not more than one living micro-organism is present in 1 x 10⁶ sterilized units of the final product.

The physical validation of the sterilizer is conducted to verify the temperature and humidity in the sterilization load and the pressure in the sterilizer during the whole cycle.

The biological validation is performed in accordance with ISO 11135:2014 Annex B "Conservative determination of lethal rate of the sterilization process – Overkill approach" part B.1.2.a "Half cycle approach". This resulted in a holding time of 120 min for the sterilization cycle to assure a SAL of at least 10⁻⁶ according to the requirements of ISO 11135:2014.

The allowable limits for residual EO and ECH are calculated taking into consideration the categorization of the K-Pack Enhance Needle as a device with limited exposure for which the cumulative single, multiple or repeated use or contact is up to 24 hours based on the approached described in ISO 10993-7:2008 second edition.

The limits for the bacterial endotoxin testing LAL (Limulus Amebocyte Lysate) performed as part of the release criteria are aligned with the requirements described in USP <85> and <161>.

Accelerated aging is performed based on ASTM F1980: "Standard Guide for Accelerated Aging of Sterile Barrier Systems for Medical Devices" to support 5 years shelf life.
