No
The device description focuses on the materials, manufacturing process, and mechanical design of a hip implant system. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML.
Yes.
The device is indicated for use in total hip arthroplasty for reduction or relief of pain and/or improved hip function in patients with various conditions, which are therapeutic goals.
No
The device is an acetabular system used in total hip arthroplasty, which is a surgical treatment for pain and improved hip function, not a diagnostic tool.
No
The device description clearly outlines physical components made of titanium alloy and UHMWPE, such as the cup, liner, and screws, which are hardware.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- Device Description: The Delta TT Acetabular System is a physical implant designed to replace the hip joint in total hip arthroplasty. It is surgically implanted into the patient's body.
- Intended Use: The intended use is to reduce pain and improve hip function in patients with various hip conditions. This is a therapeutic intervention, not a diagnostic test performed on a specimen outside the body.
The description clearly indicates a surgically implanted medical device, not a device used for in vitro testing.

Device Description
The Delta TT Acetabular System consists of a Delta TT cup, a liner and a modular metal femoral head. Bone screws can also be used as additional fixation for the cup.
The Delta TT cup is manufactured using an EBM (Electron Beam Melting) process with titanium alloy powder (Ti6Al4V, ASTM F1472 - ISO 5832-3). The Delta TT cup consists of a non porous bulk interior surface and a Trabecular Titanium structure on the external surface.
The Delta TT cup has an external hemi-spherical shape. A polar threaded hole is used for introduction of the cup and mates with the polar peg of the liner when the two components are assembled. Three (3) threaded holes in lateral positions allow additional fixation of the cup using bone screws: polyethylene plugs are inserted into these holes when bone screws are not required. The Delta TT cup is designed to be coupled with ultra high molecular weight polyethylene (UHMWPE) liners by means of a taper coupling.
Delta TT cups are available with external diameters of 44, 46 and 48 mm (for Small liners), 50 and 52 mm (for Medium liners) and 54, 56, 58, 60, 62 and 64 mm (for Large liners). The new sizes of the Delta TT Cups, the Delta TT Jumbo Cups, are Delta TT Cups with external diameters of 66, 68, 70, 72, 74 and 76mm and they are all intended to be used with Large Delta TT cup liners that were cleared in K112898. The liners are manufactured from standard UHMWPE (ASTM F648 - ISO 5834-2) or from cross-linked UHMWPE (X-Lima).
Liners are coupled with the Delta TT cup by means of a taper coupling. Two features are intended to give stability to the coupling, a peripheral ring and a polar peg. The peripheral ring is manufactured from Ti6A14V (ASTM F1472 - ISO 5832-3) and surrounds the taper of the liner circumferentially, enhancing the rotational stability of the coupling. The polar peg fits into the polar hole of the cup, increasing the lever-out stability of the top of the peg is resurfaced by a Ti6Al4V (ASTM F1472 - ISO 5832-3) plug to avoid direct contact between polyethylene and bone.
The polyethylene liners are available in two (2) versions: neutral and protruded. The protruded design provides greater coverage of the femoral head and is intended to reduce the risk of dislocation. For both the designs, the following sizes are available:
- Cross-linked UHMWPE liners: Small (for femoral heads Ø 28 mm), Medium (for femoral heads Ø 28 and 32 mm) and Large (for femoral heads Ø 28, 32 and 36 mm).
- Standard UHMWPE liners: Small, Medium and Large liners for femoral heads Ø 28 mm.
Bone screws are manufactured from Ti6Al4V (ASTM F1472 -- ISO 5832-3) and can be used to provide additional initial stability to the cup. Bone screws have a diameter of 6.5 mm and are available in lengths of 20, 25, 30, 35, 40, 45, 50, 55 and 60 mm.

§ 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)
