Intended Use

The suture anchors are intended for the fixation of soft tissue to bone.

Device Story

TWINFIX FT PK is a preloaded suture anchor system used for soft tissue-to-bone fixation. The device consists of a PEEK (polyaryletherketone) anchor preloaded with ultra-high molecular weight polyethylene suture, mounted on a stainless steel inserter. It utilizes a 'tap and twist' insertion mechanism. The device is intended for use by surgeons in clinical settings for various orthopedic procedures involving the shoulder, elbow, foot, ankle, and knee. It functions as a mechanical fastener to secure soft tissue to bone, facilitating healing and repair.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Materials: PEEK (polyaryletherketone) anchor, ultra-high molecular weight polyethylene suture, stainless steel inserter. Design: 5.5/6.5 mm tap-and-twist suture anchor. Sterilization: Ethylene Oxide (EO).

Indications for Use

Indicated for reattachment of soft tissue to bone in the shoulder (Bankhart repair, SLAP lesion, capsular shift/capsulolabral reconstruction, acromioclavicular separation, deltoid repair, rotator cuff repair, biceps tenodesis), elbow (ulnar/radial collateral ligament reconstruction, lateral epicondylitis repair, biceps tendon reattachment), foot and ankle (hallux valgus, medial/lateral instability, Achilles tendon, midfoot, metatarsal ligament/tendon repairs/reconstructions), and knee (medial/lateral/posterior oblique collateral ligament, patellar realignment, vastus medialis obliquous advancement, iliotibial band tenodesis).

Regulatory Classification

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.

Dear Ms. Boushell:

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.
