The Sub-Talar Lok is intended for the following pathological conditions resulting from disease, injury, or other trauma. - Hypermobile pes valgus - Posterior tibial tendon dysfunction - Severe pronation - Subtalar instability - Hypermobile flexible congenital flat foot
Device Description
The Instratek Sub-Talar Lok Implant is designed to stabilize the subtalar joint of the hyperpronated foot. The implant is conical shaped with external threads of uniform depth and pitch. The device is cannulated for use with a guide wire. The product will be provided with a procedure kit containing: Five (5) dilators sized 7 through 11 mm Ten Sub-Talar Lok implants, two each of five sizes Regular driver, 4.3mm hex head Rescue driver, threaded
More Information

Not Found

No
The 510(k) summary describes a mechanical implant and surgical tools, with no mention of AI, ML, image processing, or data-driven performance metrics.

Yes
The device is described as an "arthroereisis implant" that "restricts excessive subtalar pronation" and provides for "more normal subtalar joint motion in patients" for various pathological conditions, indicating a therapeutic intent to treat or alleviate a medical condition.

No
The device is an implant designed to restrict excessive subtalar pronation, which is a treatment rather than a diagnostic function. Its description focuses on stabilization and physical characteristics for implantation, not on identifying a condition.

No

The device description clearly states it is an "implant" and describes physical components like threads, cannulation, dilators, and drivers, indicating it is a hardware device.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This information is used for diagnosis, monitoring, or screening.
  • Device Description: The Instratek Sub-Talar Lok is an implant designed to be surgically placed within the human body (specifically, the subtalar joint). It is a physical device that restricts movement.
  • Intended Use: The intended use describes the device's purpose in treating specific pathological conditions by physically stabilizing a joint. It does not involve analyzing biological specimens.

Therefore, based on the provided information, the Instratek Sub-Talar Lok is a surgical implant, not an In Vitro Diagnostic device.

§ 888.3040 Smooth or threaded metallic bone fixation fastener.

(a)
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.(b)
Classification. Class II.

Dear Mr. Seavey:

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. Isting 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.

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.
