No
The summary describes a physical implant and surgical screws, with no mention of software, algorithms, or data processing that would indicate AI/ML. The manufacturing process (DMLS) is a form of additive manufacturing, not AI/ML.
Yes.
Explanation: The device is an implantable hip prosthesis designed to replace severely painful and/or disabled joints due to various conditions, directly addressing and treating a medical condition.
No
Explanation: This device is an orthopedic implant (acetabular shells and screws for total hip arthroplasty), used for treatment, not for diagnosing a condition.
No
The device description clearly states that the device is a sterile implantable device made of metal (titanium alloy and Co-Cr-Mo alloy) and is intended for use in total hip arthroplasty. This indicates a physical, hardware-based medical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is designed for cementless use in total hip arthroplasty in primary or revision surgery. This is a surgical procedure involving the implantation of a medical device into the body.
- Device Description: The device description details the components of the hip implant (acetabular shells and screws) and their manufacturing process. These are physical implants intended for surgical use.
- Lack of IVD Characteristics: An In Vitro Diagnostic device is used to examine specimens derived from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening. The provided information does not mention any such use or interaction with bodily specimens for diagnostic purposes.
- Performance Studies: The performance studies described are related to the mechanical properties, stability, and biocompatibility of the implant, which are relevant for an implantable surgical device, not an IVD.
Therefore, the Mpact® 3D Metal™ implants are a surgical implant, not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use

Device Description
The Mpact® 3D Metal Implants - DMLS Technology are sterile implantable devices intended to be used during Total Hip Arthroplasty. The devices subject of this submission are:
- Mpact® 3D Metal Acetabular Shells Two-Hole Ø 46-66 mm manufactured through DMLS Technology;
- . Mpact® 3D Metal Acetabular Shells Multi-Hole - Ø 46-72 mm - manufactured through DMLS Technology:
- . Mpact® 3D Metal Acetabular Shells Multi-Hole Thin - Ø 48-60 mm - manufactured through DMLS Technology; and
- . Compression Polyaxial Locking Screws - 11 sizes depending on screw length: from 20 to 70mm in 5mm steps.
The Mpact® 3D Metal Acetabular Shells manufactured through DMLS Technology are a line extension to the Mpact® 3D Metal Acetabular Shells and 3D Metal Augments (K171966) and to the Mpact® Acetabular Systems Shells (K103721, K122641 and K132879) and are designed to be used with the Medacta Total Hip Prosthesis System.
The subject Mpact® 3D Metal Acetabular Shells are manufactured using a Direct Metal Laser Sintering (DMLS) process with titanium alloy powder. DMLS is a metal additive layer manufacturing process that uses a precise and high-wattage laser to "sinter" powdered metals and alloys to form accurate, complex and fully-functional metal parts directly from CAD data.
Compression Polyaxial Locking Screws have been designed to provide fixation of implants to the cancellous bone and they can be considered a line extension to the predicate devices, Cancellous Bone Screws flat head, previously cleared within K103721 and K132879. The subject screws have a thread diameter of 6.5 mm and they can be coupled with implants that have dedicated fixation holes with a spherical seat shape of Ø8mm.
The outer screw of the Compression Polyaxial Locking Screws is made of titanium alloy (Ti6-Al4-V) according to ISO 5832-3:2016, Implants for Surgery - Metallic materials - Part 3: Wrought titanium 6aluminum 4-vanadium alloy, while, the inner part, not in contact with bone, is made of Co-Cr-Mo alloy according to ISO 5832-12:2019, Implants for Surgery - Metallic materials - Part 3: Wrought cobaltchromium-molybdenum alloy.

§ 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)
