Indications for Use
SeptAlign is used to support and straighten deviations in septal cartilage when sufficient healthy cartilage exists, and the cartilage is appropriately mobilized utilizing standard septoplasty techniques.
Device Story
SeptAlign is a bioabsorbable implant system for mechanical correction of nasal septal deviations. The device consists of a polydioxanone implant with bi-directional anchors and a single-use delivery tool featuring a stainless steel trocannula. Used in a surgical setting by physicians, the device is placed into the nasal septum to provide mechanical traction, holding cartilage in a straightened position during the remodeling process. The implant is fully resorbed within six months. The delivery tool includes a depth indicator for tactile feedback and an actuator lock to prevent premature deployment. The implant is trimmed to size during the procedure. The device benefits patients by providing a minimally invasive method to stabilize septal cartilage without requiring cartilage resection.
Clinical Evidence
No clinical or animal performance testing was required. Substantial equivalence is supported by bench testing, including design verification and validation, implant performance/integrity, mechanical integrity of the delivery tool, physician usability in a clinically relevant model, and simulated use functionality. Biocompatibility was evaluated per ISO 10993-1. Sterilization (EtO) validated to SAL 10^-6 per ISO 11135-1; pyrogen limits confirmed per USP <85>.
Technological Characteristics
Bioabsorbable polydioxanone implant; stainless steel trocannula; ABS and PVC components. Mechanical sensing via depth indicator. Sterilization: EtO (ISO 11135-1). Shelf-life: 6 months. Dimensions: 100mm length, 0.65mm thickness. Single-use, sterile, prescription-only.
Indications for Use
Indicated for adults requiring support and straightening of septal cartilage deviations where sufficient healthy cartilage exists and is mobilized via standard septoplasty.

Dear Tracey Henry:
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 (the 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 available 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.

SeptAlign (K251790)
## IV. DEVICE DESCRIPTION
SeptAlign consists of a bioabsorbable implant and single use delivery device. The polydioxanone implant is 100 mm long and 0.65 mm thick with bi-directional anchors which enable mechanical correction of cartilaginous nasal septal deviations without cartilage resection. The implant also includes a surgical (implant) needle to enable placement which is trimmed off after use. The implant supports the cartilage in the straightened positioned as the cartilage remodels and is fully resorbed within a 6-month period.
The implant is provided preloaded into a disposable delivery tool comprised of a non-patient contacting handle assembly and a medical grade stainless steel trocannula. The delivery tool enables placement of the distal portion of the implant in a minimally invasive manner.
SeptAlign is provided sterile and is intended for single-use only.
## V. INDICATIONS FOR USE
SeptAlign is used to support and straighten deviations in septal cartilage when sufficient healthy cartilage exists, and the cartilage is appropriately mobilized utilizing standard septoplasty techniques.

## VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE
The subject and predicate device share the same technological characteristics. Both devices utilize a bioabsorbable polydioxanone implant to support and straighten septal cartilage via bi-directional anchors which are secured through the septum, distal and proximal to the deviation. The implant in both devices applies mechanical traction to the straightened cartilage throughout the cartilage remodeling process and is resorbed within six months. Both devices utilize a single-use delivery tool for placement of the distal anchor portion of the implant in the septum. The proximal end of the implant is placed with an implant needle for both devices, which is trimmed off along with any excess implant material.
The subject device differs from the predicate device with respect to changes in the geometry of the implant features (shorter implant with wider anchors positioned closer together). The subject device delivery tool was also updated to improve the ease of use, specifically with regard to deploying the implant and securing the distal anchor. The subject device also includes two new features, a Depth Indicator attached to the trocannula which provides tactile physician feedback when puncturing the cartilage, and an actuator lock which prevents inadvertent deployment of the implant.
The subject device also includes new packaging designed to simplify presentation of the sterile product to the user.
