Device Story

The Entellus Medical Reinforced Anesthesia Needle is a 3.5-inch, 27-gauge disposable needle designed for transnasal administration of local anesthetics. It features a reinforcing sleeve to minimize needle flex and a distal bend to facilitate access to nasal anatomy. The device includes a standard luer-lock hub and a Quincke tip that extends 2 mm beyond the sleeve, acting as a distal stop. It is intended for use by clinicians to provide regional anesthesia. The device functions by manual injection of anesthetic solutions. It provides a stable, reinforced delivery mechanism compared to standard needles, potentially improving procedural access and control during nasal interventions.

Clinical Evidence

No clinical or animal testing was performed. Evidence consists of bench testing, including biocompatibility (ISO 10993-1: cytotoxicity, sensitization, intracutaneous reactivity, systemic toxicity, pyrogenicity), sterilization validation (ISO 11137-1), and design verification/validation (dimensional, strength, HFE/UE testing per ISO 594-2, ISO 9626, ISO 7864). Results confirmed the device meets design specifications.

Technological Characteristics

Stainless steel cannula, plastic luer-lock hub. 27-gauge, 3.5-inch length. Features a reinforcing sleeve and 18-degree distal bend. Quincke tip style. Sterile, single-use. Biocompatible per ISO 10993-1. Standards: ISO 594-2 (luer), ISO 9626 (needle tubing), ISO 7864 (sterile needles), ISO 11137-1 (sterilization).

Indications for Use

Indicated for patients requiring regional anesthesia via injection of local anesthetics. No specific contraindications noted.

#### Device Description:

The Entellus Medical Reinforced Anesthesia Needle is a 3.5" long disposable medical device that allows the user to transnasally administer anesthetic solutions. The Reinforced Anesthesia Needle device is a 27 gauge needle with a reinforcing sleeve which supports the needle to reduce needle flex during administration of anesthetic solutions. A slight bend at the distal end of the needle is designed to improve access to nasal anatomy. The Quincke tip extends approximately 2 mm past the reinforcing sleeve creating a distal stop. The needle hub features a standard luerlock connector.

Image /page/3/Figure/7 description: This image shows a needle with several labels. The first label points to the left side of the needle and says "Needle Hub". The next label is above the needle and says "Needle Reinforcing Sleeve". On the right side of the image, there is a close up of the needle tip with two labels: "Needle Distal Tip (27 ga.)" and "Needle Distal Stop".

# Indications for Use/ Intended Use

For use in injecting local anesthetics into a patient to provide regional anesthesia

### Contraindications:

None known.

### Technological Characteristics:

The technological characteristics of the subject device are very similar to the predicate device [K091758], including: principle of operation, design, function, materials, biocompatibility and sterility.

Both the subject device and predicate device [K091758] are needles comprised of stainless steel cannulae attached to needle luer hubs comprised of plastic. They both provide a means to administer local anesthetic solutions to provide regional anesthesia. Both devices are provided sterile, single use only and are biocompatible per ISO 10993-1. Both device designs incorporate the same Quincke tip style, length, gauge, and luer hub. The subject device reinforcement is provided by a needle reinforcing sleeve whereas the predicate device [K091758] is reinforced by a stylet. The subject device has an 18 degree bend on the distal end whereas the predicate device [K091758] is provided straight.

### Substantial Equivalence:

The indication for use and intended use of the subject device is similar to the predicate device [K091758]; the differences are semantic. The technological characteristics of the subject device are very similar to the predicate device [K091758], including: principle of operation, design, function, materials, biocompatibility, and sterility.

#### Performance Data:

Performance testing for the Reinforced Anesthesia Needle consisted of biocompatibility testing per ISO 10993-1, sterilization validation per ISO 11137-1, design verification, design validation, packaging, and shelf life per ISO 594-2, ISO 9626 and ISO 7864. Biocompatibility testing included cytoxicity, sensitization, intracutaneous reactivity, systemic toxicity, and pyrogen testing. Design verification included dimensional, strength, and Human Factors Engineering & Usability Engineering (HFE/UE) testing. Design validation included HFE/UE testing. Animal and clinical testing were not performed. Performance testing showed that the device meets design specifications and performed as intended.

## Conclusion

In conclusion, the subject device is substantially equivalent to the predicate device based on a comparison of intended use, indications for use, and technological characteristics. The subject device is as safe, as effective, and performs as well as or better than the predicate.
