Intended Use

The LATERA Absorbable Nasal Implant System is indicated for supporting upper and lower lateral nasal cartilage.

Device Story

System supports upper and lower lateral nasal cartilage; consists of absorbable implant, delivery device, and external positioning guide. Implant is PLLA-PDLA copolymer, cylindrical, 1mm diameter, 20mm or 24mm length; distal end forked for anchoring; proximal end flexible. Delivery device uses 16-gauge stainless steel cannula for minimally invasive placement. Used by clinicians in clinical settings. Implant provides structural support to nasal cartilage; benefits patients by addressing nasal valve collapse or related structural deficiencies. Device is sterile, single-use.

Clinical Evidence

Bench testing only. Performance data included design verification, shelf life, and sterilization testing to support the additional implant size and modifications. All tests passed, confirming the device meets design specifications.

Technological Characteristics

Implant material: PLLA-PDLA copolymer. Delivery device: medical grade stainless steel 16-gauge cannula. Form factor: cylindrical implant (1mm diameter, 20mm/24mm length). Sterile, single-use. No software or electronic components.

Indications for Use

Indicated for supporting upper and lower lateral nasal cartilage. Contraindicated in patients with active infection at the implantation site or known/suspected allergy to PLA or absorbable materials.

Regulatory Classification

Identification

Ear, nose, and throat synthetic polymer material is a device material that is intended to be implanted for use as a space-occupying substance in the reconstructive surgery of the head and neck. The device is used, for example, in augmentation rhinoplasty and in tissue defect closures in the esophagus. The device is shaped and formed by the suregon to conform to the patient's needs. This generic type of device is made of material such as polyamide mesh or foil and porous polyethylene.

Dear Karen Peterson:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's

{1}------------------------------------------------

requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

#### Device Description:

The LATERA Absorbable Nasal Implant System is intended to support upper and lower lateral cartilage in the nose. The system consists of the LATERA Absorbable Nasal Implant) and Delivery Device (Delivery Device). An Implant Positioning Guide is provided to serve as an external visual planning aid prior to Implant placement. The Implant is composed of a PLLA-PDLA copolymer that is predominantly cylindrical in shape with an approximate diameter of 1mm and lengths of 20mm and 24mm. The distal end of the Implant is forked to facilitate anchoring during implantation and the proximal end is narrower for increased flexibility. The disposable Delivery Device is comprised of a non-patient contacting handle assembly and a medical grade stainless steel 16-gauge delivery cannula. The Delivery Device enables placement of the Implant in a minimally invasive manner. Each Implant length (20mm, 24mm) is compatible with the Delivery Device packaged with the Implant. The LATERA Absorbable Nasal Implant System is provided sterile and is intended for single-use only.

### Indication for Use:

The LATERA® Absorbable Nasal Implant System is indicated for supporting upper and lower lateral nasal cartilage.

## Contraindications:

- Presence of an active infection at the implantation site.
- Patients known or suspected to have an allergy to PLA or absorbable materials.

## Technological Characteristics:

The LATERA Absorbable Nasal Implant System (subject device) has the same indications for use and fundamental scientific technology as the predicate device LATERA Absorbable Nasal Implant System [K161191].

The subject device has the same technological characteristics (i.e., principle of operation, basic design, manufacture process, functionality, materials, biocompatibility, and sterile packaging) as the predicate device. The subject device adds an additional implant size (length of 20mm). Other changes made since the predicate clearance include modified implant geometry, extended shelf life, and modified sterilization process.

### Substantial Equivalence:

The LATERA Absorbable Nasal Implant System has the same indications for use and fundamental scientific technology as the predicate device. LATERA Absorbable Nasal Implant System is substantially equivalent to the predicate device.

### Performance Data:

Performance testing of the LATERA Absorbable Nasal Implant System consisted of design verification testing and distribution testing to support the additional implant size. Design verification testing, shelf life testing, and sterilization testing were completed to support the device modifications made since the predicate clearance. All testing passed and showed that the device meets design specifications and performed as intended.

#### Conclusion:

In conclusion, the indications for use and technological characteristics are the same as or equivalent to the predicate device. Performance testing has demonstrated that the device is as safe and as effective as the predicate device and that its performance is substantially equivalent to the predicate device.
