The document describes a mechanical hip implant system and its intended use, with no mention of AI or ML technology in the device description, intended use, or performance studies.
Yes.
The device is a hip implant intended to reconstruct or replace parts of a severely disabled and/or very painful hip joint, which is a therapeutic intervention aimed at alleviating pain and restoring function.
No
The device is described as a "femoral hip prosthesis" and is intended for "primary or revision reconstruction" of the hip joint, indicating it is a treatment device, not a diagnostic one.
No
The device description clearly states it is a "matrix of interchangeable components (STEM, BODY, ACTUATOR, FEMORAL HEAD)" which are physical parts of a hip prosthesis, indicating it is a hardware device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a device for surgical implantation to reconstruct the femoral portion of the hip joint. This is a therapeutic and structural device, not a diagnostic one.
- Device Description: The description details a system of interchangeable components that form a femoral hip prosthesis. This is consistent with a surgical implant.
- Lack of Diagnostic Elements: There is no mention of analyzing samples from the human body (like blood, urine, tissue, etc.) or providing information for diagnosis, monitoring, or screening.
- Performance Studies: The performance studies mentioned are static and fatigue tests, and corrosion resistance, which are relevant for the structural integrity and biocompatibility of an implant, not for diagnostic accuracy.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic purposes. This device is a surgical implant used to treat a physical condition.

Device Description
The ActiveLock M Modular Femoral Hip System is a matrix of interchangeable components (STEM, BODY, ACTUATOR, FEMORAL HEAD) that can be locked together to form a single femoral hip prosthesis. A description of the components is given below.
Stem: The Stem component is cylindrical, straight, and fluted with a slot in the coronal plane that extends along the distal third of its length. The proximal aspect of the Stem is a smooth tubular cvlinder designed to mate with the Body component. The Stem component is manufactured from wrought Ti 6Al-4V alloy and is offered in a variety of lengths, straight or curved, to accommodate primary and revision surgery.
Body: The Body component is wedge-shaped and symmetrical in the coronal plane. Design variations of the Body include primary, revision, and calcar replacement components. All Body designs incorporate identical cylindrical bores for modular attachment to the Stem and the same modified Morse taper for attachment of Metagen Femoral Heads. All Body designs are available with either porous CpTi plasma spray or plasma-sprayed smooth HA (hydroxyapatite) coating. The Body component is manufactured from wrought Ti 6A1-4V alloy. When attached to the Stem component, the Body component provides fixation to the proximal metaphyseal region of the femur.
Actuator: The Actuator is manufactured of Nickel-Titanium alloy (NiT). It is a cylindrical, tubular locking component.
Femoral Head: The Femoral Head is a CoCr alloy articulating component with a modified female Morse taper. The components are spherically ground and polished to 22 mm, 26 mm, and 32 mm diameters, and are available in four offsets -- 5 mm, 0 mm, +5 mm, and +10 mm.
Components are matched according to four distinct "FAMILY" designations. The four families are the "A" family, "B" family, "C" family, and the "D" family. The "A" family corresponds to the smallest sizes, the "B" and "C" family to the mid-range sizes, and the "D" family to the largest sizes. The Stem and Body components are only interchangeable within their respective families, and can only be locked by the Actuator in that family.
Composition/Materials: The ActiveLock "" Modular Femoral Hip System is composed of titanium alloy (Ti-6AI-4V ELI) conforming to ASTM Specification F136. The Femoral Head is made from wrought Co-Cr-Mo alloy conforming to ASTM Specification F1537.
The Actuator of the ActiveLock™ Modular Femoral Hip System is made from NiTi alloy, a nickel-titanium shape memory alloy. NiTi alloy is currently being used in a number of implant devices and has a long clinical history as an implant material. In addition, NiTi alloy is being used in orthopedic applications for bone anchors.

§ 888.3358 Hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis.
(a)
Identification. A hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis is a device intended to be implanted to replace a hip 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 has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement.(b)
