Intended Use

The SubQ It!™ Bioabsorbable Skin Closure System is intended for use in humans for abdominal, thoracic, gynecologic, orthopedic, plastic and reconstructive surgery for the subcuticular closure of skin where an absorbable tissue fastener is desired for temporary tissue approximation.

Device Story

SubQ It! Bioabsorbable Skin Closure System consists of bioabsorbable fasteners and a manual stapler; used for subcuticular skin closure. Fasteners feature two legs with barbed tips; composed of 82/18 L-lactide/Glycolide copolymer. Device is pre-loaded, single-patient use, and sterile. Operated by surgeons in clinical settings (abdominal, thoracic, gynecologic, orthopedic, plastic, reconstructive). Surgeon manually deploys fasteners to approximate tissue edges; fasteners provide temporary closure while absorbing over time. Benefits include reduced need for suture removal and potential for improved cosmetic outcomes. No clinical data; performance established via bench and porcine animal models.

Clinical Evidence

No clinical data performed. Evidence based on GLP-compliant porcine animal model studies (7cm, 2cm, and 1cm incisions) over 90 days, bench testing, shelf-life mechanical performance studies, packaging tests, and biocompatibility testing.

Technological Characteristics

Fasteners: 82/18 L-lactide/Glycolide copolymer; 4.3mm length, 0.88mm diameter, 2.75mm spacing. Manual stapler delivery system. Sterilization: Gamma radiation. Single-patient use.

Indications for Use

Indicated for humans undergoing abdominal, thoracic, gynecologic, orthopedic, plastic, or reconstructive surgery requiring subcuticular skin closure for temporary tissue approximation.

Regulatory Classification

Identification

Submission Summary (Full Text)

{0}------------------------------------------------

On October 8, 2021, FDA issued a final order reclassifying surgical staplers intended for internal use (formerly regulated under the classification for "manual surgical instrument for general use") from class I (general controls) into class II (special controls) and subject to premarket review. See here:

https://www.federalregister.gov/documents/2021/10/08/2021-22041/general-and-plastic-surgery-devices-reclassification-of-certainsurgical-staplers.

As part of this reclassification, FDA also amended the existing classification for "manual surgical instrument for general use" to remove staplers and to create a separate classification regulation for surgical staplers that distinguishes between surgical staplers for internal use and external use. Under the new regulation, 21 CFR 878.4740, surgical staplers for internal use are classified into class II with special controls, while surgical staplers for external use remain in in class I, exempt from premarket notification.

Dear Rosina Robinson, RN, MED, RAC:

The Food and Drug Administration (FDA) is sending this letter to notify you of an administrative change related to your previous substantial equivalence (SE) determination letter dated April 09, 2014. Specifically, FDA is updating this SE Letter to reflect an administrative change corresponding to the reclassification of certain surgical staplers, as detailed in the final order published on October 8, 2021 (see here for more information: https://www.federalregister.gov/documents/2021/10/08/2021-22041/general-and-plasticsurgery-devices-reclassification-of-certain-surgical-staplers). As part of this reclassification, FDA has amended the existing classification for "manual surgical instrument for general use" to remove staplers and to create a separate classification for surgical staplers that distinguishes between surgical staplers for internal use and external use. Under the new regulation, 21 CFR 878.4740, surgical staplers for internal use are classified into class II with special controls, while surgical staplers for external use remain in class I, exempt from premarket notification. As a result of the final order, FDA has created a new product code (OOS) to better categorize surgical staplers for external use.

#### SUMMARY OF TECHNOLOGICAL CHARACTERISTICS COMPARED TO THE 6. PREDICATE DEVICE/S

The SubQ It!" Bioabsorbable Skin Closure System is substantially equivalent to the INSORB™ Absorbable Staple when used with the INSORB Subcuticular Skin Stapler manufactured by Incisive Surgical, Inc. The intended use is the same, the fasteners are similar in size and material, with similar strength and mass. Both the new device and the predicate are sterilized by gamma radiation and pre-loaded into a manual stapler, packaged for single patient use.

#### SUMMARY OF NON-CLINICAL PERFORMANCE TESTING AS BASIS FOR SUBSTANTIAL 7. EQUIVALENCE

The SubQ It!" Bioabsorbable Skin Closure System was tested side-by-side with the INSORB™ device in 7cm long incisions in a GLP compliant porcine animal model for 90 days. Data show no significant differences between the SubO It!" and the predicate device.

#### 8. SUMMARY OF CLINICAL TESTING AS BASIS FOR SUBSTANTIAL EQUIVALENCE

Clinical testing has not been performed.

#### SUMMARY OF OTHER INFORMATION 9.

The SubQ It!™ Bioabsorbable Skin Closure System was also tested in 1 cm and 2 cm incisions in a GLP compliant porcine animal model, subjected to bench tests, shelflife study of mechanical performance, and packaging tests. These studies demonstrate the safety and effectiveness of the SubQ It!" Bioabsorbable Skin Closure System for its intended use. Additionally, the finished, sterilized product met requirements of biocompatibility tests.

### 10. CONCLUSIONS DRAWN FROM NON-CLINICAL AND CLINICAL TESTS

Based on descriptive information and test results, Opus KSD, Inc. has determined that the SubQ It!" Bioabsorbable Skin Closure System is substantially equivalent to the INSORB™ Absorbable Staple manufactured by Incisive Surgical, Inc., that differences between the two products are minor, and raise no new issues of safety and effectiveness.
