Intended Use

LiquiBand® Plus is intended for topical applications only, to hold closed easily approximated skin edges of wounds from surgical incisions, including punctures from minimally invasive surgery and simple, thoroughly cleansed, trauma induced lacerations. LiquiBand® Plus may be used in conjunction with, but not in place of, deep dermal stitches.

Device Story

LiquiBand Plus is a sterile, single-patient-use topical skin adhesive. It consists of a crushable glass ampoule containing 2-octyl-cyanoacrylate monomer and D&C Violet #2 colorant, housed within a plastic applicator with a foam tip. The foam tip contains an adhesive accelerant. The device is used by clinicians in a clinical setting to close skin wounds. Upon application, the adhesive polymerizes within minutes to form a film that holds skin edges together. It acts as a microbial barrier while the film remains intact. The device provides a non-invasive method for wound closure, potentially reducing the need for traditional sutures or staples in appropriate cases.

Clinical Evidence

Bench testing included lap-shear strength (ASTM F2255-05), T-peel adhesion (ASTM F2256-05), tensile strength (ASTM F2258-05), wound closure strength (ASTM F2458-05), degradation rate, heat of polymerization, force to actuate, viscosity, set/clog time, microbial barrier, and film quality. Biocompatibility testing addressed cytotoxicity, sensitization, irritation, acute/subacute systemic toxicity, implantation, and material-mediated pyrogenicity per ISO 10993-1. An animal wound healing study was also conducted. No clinical human trials were performed.

Technological Characteristics

Materials: 2-octyl-cyanoacrylate monomer, D&C Violet #2, polyethylene tip base, foam applicator. Energy: Chemical polymerization. Form factor: Single-patient-use applicator with crushable glass ampoule. Connectivity: None. Sterilization: Not specified. Standards: ASTM F2255-05, F2256-05, F2258-05, F2458-05; ISO 10993-1.

Indications for Use

Indicated for topical closure of easily approximated skin edges of surgical incisions (including minimally invasive surgery) and simple, cleansed, trauma-induced lacerations. May be used with deep dermal stitches. No specific age or gender restrictions noted.

# Dear Martin Mitchell:

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 requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part

#### Device Description

LiquiBand® Plus topical skin adhesive is a sterile, liquid topical skin adhesive containing a monomeric (2-Octyl-cyanoacrylate) formulation and the colorant D&C Violet #2. It is provided in a single patient use applicator and packaged in a pouch. The LiquiBand® Plus topical skin adhesive product is comprised of a crushable glass ampoule contained within a plastic applicator with attached foam applicator tip. LiquiBand® Plus topical skin adhesive remains liquid until it is applied to the skin. Upon application LiquiBand® Plus topical skin adhesive polymerizes within minutes.

In vitro studies have shown that LiquiBand® Plus topical skin adhesive acts as a barrier to microbial penetration as long as the adhesive film remains intact. Clinical studies were not conducted to demonstrate microbial barrier properties and a correlation between microbial barrier properties and a reduction in infection have not been established.

#### Indications for Use

LiquiBand® Plus is intended for topical applications only, to hold closed easily approximated skin edges of wounds from surgical incisions, including punctures from minimally invasive surgery and simple, thoroughly cleansed, trauma induced lacerations. LiquiBand® Plus may be used in conjunction with, but not in place of, deep dermal stitches.

#### Comparison of Technological Characteristics with the Predicate Device

A comparison of the technological characteristics of LiquiBand® Plus and the predicate device are outlined below:

- . Applicator tip: LiquiBand® Plus has a polyethylene tip base and foam. The predicate has a polypropylene tip base and a polyurethane foam.
- . Adhesive accelerant: LiquiBand® Plus contains an accelerant in the foam tip.
- . Applicator body: The LiquiBand® Plus applicator has the same design but is 10mm shorter in length compared to the predicate.
- Adhesive: Both devices contain a 2-octyl cyanoacrylate based adhesive with D&C Violet #2 colorant. LiquiBand® Plus contains 0.41g and the predicate contains 0.80g of adhesive.
