The device consists of a titanium body with nitinol arcs. It is implanted into bone to secure sutures, which in turn hold the tissue. Unlike the predicate Mitek GII, which requires manual knot-tying to secure tissue, the Knotless Anchor utilizes a looped suture mechanism to achieve apposition. The device is intended for use by surgeons in orthopedic procedures involving the shoulder, ankle, foot, elbow, and knee. By eliminating the need for manual knots, the device simplifies the tissue apposition process while maintaining equivalent pull-out strength to the predicate device. ## Clinical Evidence Bench testing only. Pull-out failure force testing in pig femora showed the Mitek GII had a mean force of 55.63 lbs (SD 17.12) and the Knotless Anchor had a mean force of 60.96 lbs (SD 14.29), demonstrating statistically equivalent strength. ## Technological Characteristics Titanium body and Nitinol arcs. Dimensions: 0.430" length by 0.109" width with two 0.026" by 85-degree arcs. Mechanical fixation device. ## Regulatory Identification A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system. ## Predicate Devices - Mitek GII ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

ADDRESS: 60 Glacier Drive, Westwood, MA 02090 TEL#: 781-251-2700 CONTACT: Robert Zoletti, Manager, Regulatory Affairs DATE: November 19, 1997 NAME OF DEVICE CLASSIFICATION NAME: Staple, fixation, bone & soft tissue COMMON NAME: Device for holding soft tissue in apposition PROPRIETARY NAME: Mitek Knotless Anchor PREDICATE DEVICE Mitek GII DESCRIPTION OF DEVICE FUNCTION Hold soft tissue in apposition during healing process DEVICE DESIGN The device is 0.430" lg by 0.109" wide with with two 0.026" by 85 degree arcs. MATERIALS USED Titanium body and Nitinol arcs INTENDED USE To lock into bone and hold suture and tissue in apposition during the healing process COMPARISON TO PREDICATE DEVICE Identical intended use with variance in suture handling and knotless function. Made from identical materials. Patient preparation is same with the exception of the tissue apposition process, i.e., the knotless anchor uses a looped version of suture to hold the tissue in place and the GII uses knots to perform the tissue apposition. DESCRIPTION OF NON CLINICAL TESTS Bench top tests showed statistically equivalent strength between the knotless and GII anchors. The pull out failure force from pig femora for : Mitek GII Anchor was 55.63lbs, SD 17.12, and for Knotless Anchor was 60.96lbs, SD 14.29. 003006 {1} DESCRIPTION OF CLINICAL TESTS Clinical tests for the Mitek anchors were done in accordance with IDE G880026. CONCLUSIONS FROM TESTS The Mitek Anchor was found safe and effective by FDA in K892126. 000007 {2} DEPARTMENT OF HEALTH & HUMAN SERVICES Public Health Service Food and Drug Administration 9200 Corporate Boulevard Rockville MD 20850 FEB 13 1998 Mr. Edward F. Kent Vice President Regulatory Affairs Mitek Products 60 Glacier Drive Westwood, Massachusetts 02090 Re: K974345 Trade Name: Mitek Knotless Anchor Regulatory Class: II Product Code: MBI Dated: November 19, 1997 Received: November 19, 1997 Dear Mr. Kent: 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.
