#### 3. Substantial Equivalence

The modified Silhouette Lift device is substantially equivalent to Featherlift Silhouette Suture (original name for the device) cleared under K060414 and amended under K171005. The change to the device is limited to changes made to the shelf life (extension to 18months).

No changes have been made to the intended use or fundamental scientific technology and therefore the supporting information on sterilization, biocompatibility, and clinical data remain unchanged from the original application.

The only modification made to the predicate device is the modification to the shelf life of the device. The details and reasons for which are detailed within this 510(k).

The subject device does not raise any new questions of safety and effectiveness and therefore is substantially equivalent to the predicate.

#### 4. Device Description

Silhouette Lift Sutures are non-absorbable, sterile sutures.

SMS 01-PP-3.0.1-B-S, SMS 03-PP-3.0.1-CL and SMS 06-PP-3.0.1-B-L are made of 40.5 cm USP 3.0 size polypropylene suture with 6 cones made of a resorbable material (Lactide / Glycolyde 82:18) affixed to the suture. SMS 02-PP-2.0.1-B is a 37.3cm USP 2.0 size polypropylene suture with 10 cones made of resorbable material (Lactide / Glycolyde 82:18) affixed to the suture.

Attached to one end of each of the sutures is a straight needle and to the opposite end is a ½ circle taper needle.

All products are supplied sterile (EO) for single use only. Silhouette Lift Sutures elicit a minimal acute inflammatory reaction in tissue that is followed by gradual encapsulation.

#### 5. Intended Use/Indications for Use

Silhouette Lift Sutures are for use in midface suspension surgery to fixate the cheek sub dermis in an elevated position.

The intended use of the modified device is identical to the predicate, Silhouette Lift Suture/ Featherlift Silhouette Suture cleared under K060414 and amended under K171005.

## 7. Performance Testing

Results obtained in the stability study were in accordance with the acceptance criteria defined in the protocol and demonstrated continued sterility, package integrity and device functionality over the 18 months requested in this 510(k).

Performance data provided within the stability report confirms compliance to:

- . Peak Tensile Force at Break USP <881>
- Monofilament Diameter USP <861> .
- Swaging Test between Monofilament and Needle USP <871> .
- Sterility USP <71> .

This confirms that Silhouette Lift meets relevant USP specifications at the end of its shelf life and is equivalent to its predicate.

No clinical testing was conducted as part of this submission. Biocompatibility evaluation in according with ISO 10993-1 as performed on the predicate device remains valid and supportive for Silhouette Lift product with the extended shelf life, as there have been no new materials introduced, the materials in contact with tissues have not changed and the duration of contact remains, the same, therefore no additional testing was deemed necessary.
