The summary describes a physical implant (tibial component) and its materials, with no mention of software, algorithms, or data processing that would indicate AI/ML.
Yes
The device is a knee joint implant intended to treat severe degeneration, trauma, or other pathologies of the knee, which classifies it as a therapeutic device.
No
Explanation: This device is a component of a total knee arthroplasty, specifically a tibial component, which is an implant used in surgery. It is not designed to diagnose a condition.
No
The device description clearly states it is a physical implant comprised of Hedrocel porous tantalum and UHMWPE, available in various sizes and fixation options. This indicates it is a hardware device, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states it's for "cemented total knee arthroplasty" due to "severe degeneration, trauma, or other pathology of the knee joint." This describes a surgical implant used to treat a physical condition within the body.
- Device Description: The description details a physical component made of materials like porous tantalum and UHMWPE, designed to be surgically implanted.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (like blood, urine, or tissue) outside of the body to provide information about a physiological state, health, or disease.
IVD devices are used in vitro (in glass, or outside the body) to perform tests on biological samples. This device is an in vivo (in the living body) surgical implant.
N/A
Intended Use / Indications for Use
The Implex Hedrocel Posterior Stabilized (PS) Tibial Component is intended for use where severe degeneration, trauma, or other pathology of the knee joint indicates cemented total knee arthroplasty. In addition, the Hedrocel PS Tibial Component is indicated for use in the presence of knee instability caused by a compromised or non-functional posterior cruciate ligament.

§ 888.3560 Knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a knee joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components and a retropatellar resurfacing component made of ultra-high molecular weight polyethylene. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.

Implex Hedrocel PS Tibial Component, Cemented Regulatory Class: II Product Code: JWH Dated: November 29, 1999 Received: December 2, 1999
Dear Mr. Schalago:
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 control provisions of the Act. The general control 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 (QS) 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.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
