Device Facts

• Record ID: K023372
• Device Name: NON-BIOABSORBABLE STAPLE
• Applicant: Onux Medical, Inc.
• Product Code: NJU · General, Plastic Surgery
• Decision Date: Dec 27, 2002
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 878.4495
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The Coil Fixation Device is intended for fixation of prosthetic material and approximation of tissue in endoscopic and open surgical procedures.

Device Story

Minimally invasive sterile disposable instrument for single patient use; delivers nitinol fixation springs. Spring consists of 3 coils, approx .18 inches diameter. Instrument inserts needle through tissue or prosthetic material; spring pushed out to release 1 coil; needle withdrawn while remainder of spring deployed. Distal and proximal coils exert compression force on tissue/prosthetic material due to pre-compressed coil design. Used in endoscopic and open surgical procedures by surgeons. Benefits include secure fixation of mesh and tissue approximation.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Nitinol fixation springs; 3-coil design; approx .18 inch diameter. Mechanical delivery via needle lumen. Single-use sterile disposable instrument. No software or electronic components.

Indications for Use

Indicated for fixation of prosthetic mesh material and approximation of tissue in endoscopic and open surgical procedures.

Regulatory Classification

Identification

A stainless steel suture is a needled or unneedled nonabsorbable surgical suture composed of 316L stainless steel, in USP sizes 12-0 through 10, or a substantially equivalent stainless steel suture, intended for use in abdominal wound closure, intestinal anastomosis, hernia repair, and sternal closure.

Special Controls

*Classification.* Class II (special controls). The device, when it is a steel monofilament suture that is uncoated and does not incorporate barbs, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 878.9. The special control for this device is FDA's “Class II Special Controls Guidance Document: Surgical Sutures; Guidance for Industry and FDA.” See § 878.1(e) for the availability of this guidance document.

### Devices to Which Equivalence is Claimed

The subject device has equivalency to the EndoANCHOR produced by Ethicon Endo-Surgery, Inc. (K013749).

### Description of Subject Device

The subject device is designed to deliver fixation springs via a minimally invasive sterile disposable instrument that is for single patient use. The fixation springs are made of nitinol and are composed of 3 coils that are approximately .18 inches in diameter. The spring is held within the lumen of a needle is inserted through the tissue or prosthetic material to be approximated or fixated and the spring is pushed out so that approximately 1 coil of the spring is released. The needle is then withdrawn from the tissue or prosthetic material while the remainder of the spring is pushed out thereby deploying at least one coil on the proximal surface of the tissue or prosthetic material. Because the spring is manufactured such that the coils are naturally pre-compressed against each other, the distal and proximal coils place a compression force on the tissue or prosthetic material that holds them together.

#### Intended Use of Subject Device

Both the subject device and the EndoANCHOR are indicated for fixation of prosthetic mesh material and approximation of tissue in endoscopic and open surgical procedures.

### Comparison of Technical Aspects

The subject device and the EndoANCHOR use an elastic deformation force from nitinol fixation constructs to produce a holding force on the tissue or prosthetic material being approximated or fixated. The subject device uses a spring to compress and hold material that is between its coils while the EndoANCHOR uses opposing pairs of flexible tabs that push against and compress the material held between them.

Dear Ms. DePietro:

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. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.
