The summary describes a physical implant (femoral stem) and does not mention any software, algorithms, or data processing capabilities that would indicate the use of AI/ML.
Yes
The device is a femoral component used in total hip arthroplasty to replace a damaged hip joint, which is a therapeutic intervention.
No
The device, DePuy Luster Stem, is a femoral component for total hip arthroplasty, which is a treatment (replacement of a damaged hip joint) rather than a diagnostic tool.
No
The device description clearly states it is a physical femoral stem made of forged cobalt chrome molybdenum alloy, which is a hardware component.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health. They are used outside of the body.
- DePuy Luster Stem Function: The DePuy Luster Stem is a surgical implant used to replace a damaged hip joint within the patient's body. It is a physical component of a total hip arthroplasty procedure.
The provided information clearly describes a device that is surgically implanted, not a device used to test biological samples in a laboratory setting.
N/A
Intended Use / Indications for Use
The DePuy Luster Stem is indicated for cemented use as the femoral component in total hip arthroplasty for replacing the hip joint of a patient whose hip joint has been damaged by degenerative joint disease, fracture, or the failure of a previous arthroplasty.

§ 888.3350 Hip joint metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A hip joint metal/polymer semi-constrained cemented 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 includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.

DEVICE DESCRIPTION AND INTENDED USE:
The DePuy Luster Stem is a polished, distally tapered femoral stem with a proximal anterior/posterior flange, a medial 30° collar, and an oval driver hole in the lateral proximal shoulder. The DePuy Luster Stem is available in five sizes (1, 2, 3, 4, and 5) each with two offset options, standard and high, and is manufactured from forged cobalt chrome molybdenum alloy. The DePuy Luster Stem is indicated for cemented use as the femoral component in total hip arthroplasty for replacing the hip joint of a patient whose hip joint has been damaged by degenerative joint disease, fracture, or the failure of a previous arthroplasty.
BASIS OF SUBSTANTIAL EQUIVALENCE:
The Luster Stem is identical in design, material and intended use to the FDA cleared Endurance (K942370) femoral stem. Both stems are distally tapered femoral stems with a proximal anterior/posterior flange, a medial 30° collar, and an oval driver hole in the lateral proximal shoulder. Both stems have a 12/14mm self-locking male taper at the neck to allow for the use of interchangeable modular metal or ceramic femoral heads. Both stems are available in five sizes (1, 2. 3. 4. and 5) each with a standard and high offset option. Both stems accept a PMMA centralizer at the distal tip and may be used with a cement restrictor. Both stems are manufactured from forged cobalt chrome molybdenum alloy and are intended for cemented use as the femoral component in total hip arthroplasty for replacing the hip joint of patients whose hip joint has been damaged by degenerative joint disease, fracture, or the failure of a previous arthroplasty. The only difference
000004
1
between the Luster stem and the FDA cleared Endurance stem is that the entire surface finish of the I uster stem is polished while the Endurance stem has a matte finish on the lateral and distal stem, and is grit blasted under the proximal flange.
The Luster stem is similar in material, design, and intended use to the FDA cleared CPT Hip Prosthesis in that the both stems are manufactured from cobalt chrome, are polished, and are intended for cemented use with the use of femoral canal centering devices (i.e., centralizers). The Luster stem is similar in design and intended use to the FDA cleared Exeter Total Hip System in that hoth stems are polished and are intended for cemented use with the use of femoral canal centering devices.
Based on similarities of design, materials and intended use, DePuy believes that the Luster Stem 1s substantially equivalent to the FDA cleared Endurance, CPT, and Exeter Hip Systems.
