Intended Use
The Thorecon Rigid Fixation System is intended for use in the stabilization of fractures of the anterior chest wall including sternal fixation following sternotomy and sternal reconstructive surgical procedures. The system is intended for use in patients with normal and/or poor bone quality.
Device Description
The Thorecon Rigid Fixation System may be implanted via an open or minimally invasive approach. Where additional stability is desired, devices can be used with traditional monofilament wire or Sternal Cable of similar material. The Thorecon Rigid Fixation System includes plates (some with integrated cable subassemblies) manufactured from 316L stainless steel (ASTM F138) and screws comprised of 22Cr-13Ni-5Mn stainless steel (ASTM F1314). Non-implantable needles, used to guide the cable around the sternum, are manufactured from 420 or Custom 470 stainless steel. Thorecon devices are all single-use. The plates, complete with the necessary screws and instruments (torque driver and tensioner/cutter) required for completion of the surgery, are provided sterile in a disposable kit. Sterile instruments and screw multi-packs and a non-sterile cable/ plate cutter instrument are also available as replacements and for use during emergent re-entry, if necessary. The devices should be implanted using only the manual surgical instruments designed specifically for the implants in the system.
More Information

No
The device description focuses on mechanical components and materials for rigid fixation, with no mention of software, algorithms, or data processing that would indicate AI/ML. The performance studies are mechanical and MR safety evaluations.

Yes
The device is intended for the stabilization of fractures of the anterior chest wall following sternotomy and sternal reconstructive surgical procedures, which is a therapeutic purpose.

No

The device is described as a "Rigid Fixation System" intended for "stabilization of fractures of the anterior chest wall." Its components are plates and screws, and it is implanted surgically. This indicates it is a therapeutic device for fracture stabilization, not a diagnostic one.

No

The device description clearly outlines physical components made of stainless steel (plates, screws, needles, instruments) intended for surgical implantation and use, indicating it is a hardware medical device.

Based on the provided information, the Thorecon Rigid Fixation System is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use clearly states the device is for the "stabilization of fractures of the anterior chest wall including sternal fixation following sternotomy and sternal reconstructive surgical procedures." This describes a surgical implant used to physically support and stabilize bone, not a device used to examine specimens from the human body to provide information for diagnosis, monitoring, or compatibility.
  • Device Description: The description details plates, screws, cables, and instruments used for surgical implantation. These are all components of a surgical fixation system, not diagnostic tools.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any process related to in vitro testing.

Therefore, the Thorecon Rigid Fixation System is a surgical implant device, not an IVD.

Dear Sarah Pleaugh:

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.
