No
The summary describes a mechanical orthopedic implant and associated instrumentation, with no mention of software, algorithms, or any technology related to AI or ML.
Yes
The device is a medical implant (hip prosthesis component) used to treat specific medical conditions, which inherently makes it a therapeutic device.
No
Explanation: The device is a prosthetic hip component intended for surgical implantation to replace parts of the hip joint. It is used for treatment, not for diagnosing conditions.
No
The device description clearly states it is a physical implant system consisting of a UHMWPE liner, cobalt chrome outer shell, and UHMWPE retention ring, along with associated instrumentation. There is no mention of software as the primary or sole component.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the Ring-Lok™ Modular Bi-Polar System is a prosthesis for use in surgical procedures (hemi-arthroplasty of the hip) to treat conditions like fractures and osteonecrosis.
- Device Description: The device is described as a physical implant (UHMWPE liner, cobalt chrome outer shell, retention ring) designed to be surgically placed in the body.
- IVD Definition: In Vitro Diagnostics are devices used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening. This device does not perform any such analysis of specimens.
The Ring-Lok™ Modular Bi-Polar System is a surgical implant used in orthopedic procedures.

Device Description
The Ring-Lok™ Modular Bi-Polar System is intended for use in combination with the previously cleared femoral components including Rig-Fix™ Hip Stem (K072101), C-fit Performa (K923898) or the Stability Hip Stem (K915787 and K934457)). The Ring-Lok™ Modular Bipolar System consists of a factory assembled UHMWPE liner in a cobalt chrome outer shell, and UHMWPE retention ring. These bipolar heads include outer diameters ranging from 38 to 62 mm, in 1mm increments, to properly fit the patient anatomy. The inner diameter mates with a 22.225, 26 or 28 mm diameter femoral head.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The Ring-Lok™ Modular Bipolar System was tested as part of design verification to written protocols with pre-defined acceptance criteria. Testing included Range of Motion, Lever Out and Pull Out tests conducted on the worst case component size and option/design. The testing met all acceptance criteria and verifies that the performance of the Ring-Lok ™ Modular Bipolar System is substantially equivalent to the predicate devices.

§ 888.3390 Hip joint femoral (hemi-hip) metal/polymer cemented or uncemented prosthesis.
(a)
Identification. A hip joint femoral (hemi-hip) metal/polymer cemented or uncemented prosthesis is a two-part device intended to be implanted to replace the head and neck of the femur. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a snap-fit acetabular component made of an alloy, such as cobalt-chromium-molybdenum, and ultra-high molecular weight polyethylene. This generic type of device may be fixed to the bone with bone cement (§ 888.3027) or implanted by impaction.(b)
Classification. Class II.
