Intended Use

The LIGA-LOOP Suture Applicator is intended for use in the suturing of soft tissue and ligation of blood vessels during open and guidance-assisted surgical procedures. The LIGA-LOOP Suture Applicator with polyglycolic acid (PGA) suture and the LIGA-LOOP Suture Applicator with gut suture (plain and chromic) are intended for the same use, excluding cardiovascular and neurological procedures.

Device Story

LIGA-LOOP™ Suture Applicator is a single-use, disposable surgical instrument for soft tissue and blood vessel ligation. Device features a slide-type handpiece and J-shaped tip for grasping tissue; incorporates a central lumen for irrigation, aspiration, or imaging. Operates by passing a suture around targeted tissue/vessel using a snare mechanism; no suture needles used. Used by surgeons in open or guidance-assisted surgical procedures. Central lumen allows for fluid management during the procedure. Benefits include simplified ligation and integrated fluid management/imaging capabilities, enhancing patient safety during suturing.

Clinical Evidence

Bench testing only. Testing included knot pull strength and suture diameter measurements to ensure the applicator mechanism does not damage the suture material. No clinical data provided.

Technological Characteristics

Single-use, disposable instrument. Materials: ABS handle, stainless steel outer shaft/lumen, nitinol/stainless steel tips, epoxy potting. Operating principle: snare-based ligation without needles. Features central lumen (4.8 mm or 9 mm) for irrigation/aspiration/imaging. Dimensions: 30 Fr or 39 Fr cannula, 12 cm or 24 cm length. Sterilization: Gamma radiation (25-40 kGy).

Indications for Use

Indicated for suturing soft tissue and ligating blood vessels during open and guidance-assisted surgical procedures. Excludes cardiovascular and neurological procedures. For prescription use.

Regulatory Classification

Identification

An absorbable surgical gut suture, both plain and chromic, is an absorbable, sterile, flexible thread prepared from either the serosal connective tissue layer of beef (bovine) or the submucosal fibrous tissue of sheep (ovine) intestine, and is intended for use in soft tissue approximation.

Special Controls

*Classification.* Class II (special controls). 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.

Predicate Devices

• Endoscopic Ligation Device (K950126)

む」にはない

The LIGA-I.OOP™ Suture Applicator was tested to ensure that manipulation during installment of the suture to the applicator does not significantly affect suture diameter or knot pull-strength of the suture material. Test results indicate rcliable performance when the device is used in accordance with the Instructions for Use. Manipulation of the suture material does not affect suture diameter or knot pull-strength. The LIGA-LOOP™ Suture Applicator does not raise any new safety, effectiveness, or performance issues.

Dear Dr. Gordon:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (OS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
