The document describes a mechanical implant system and does not mention any software, algorithms, or data processing that would indicate the use of AI or ML.
No
Explanation: The device is a replacement system for parts of the femur, used in surgical procedures for conditions like trauma, tumor resections, and failed joint replacements. It functions as a prosthetic implant rather than a device that provides therapeutic treatment itself.
No
The device description indicates it is a "Distal Femoral Replacement System" composed of physical components like an "anchor plug," "spindle assembly," and "intercalary segment," which are used for "correction of revision of unsuccessful osteotomy, arthrodesis, or previous joint replacement," "tumor resections," "revision of previously failed total joint arthroplasty," and "trauma." These functions describe a surgical implant rather than a device designed to detect, diagnose, or monitor a medical condition.
No
The device description clearly outlines physical components (anchor plug, spindle assembly, intercalary segment) which are hardware. The performance studies also focus on mechanical testing of these physical components.
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 surgical implant for replacing a portion of the distal femur due to various conditions like failed previous surgeries, tumors, or trauma. This is a therapeutic intervention performed in vivo (within the body).
- Device Description: The description details the physical components of a surgical implant designed to be placed within the bone.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
IVD devices are used in vitro (outside the body) to analyze samples and provide diagnostic information. This device is a surgical implant used in vivo for structural support and replacement.

Device Description
The ComPreSs® Distal Femoral Replacement System consists of three main components, the anchor plug, the spindle assembly, and the intercalary segment. The Anchor Plug is embedded within the medullary canal, the Spindle Assembly attaches to the Anchor Plug and is compressed against the bone / implant interface at the osteotomy site. The Intercalary Segment attaches to the Spindle Assembly, and completes the Femoral Stem Component.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-Clinical Testing: Mechanical testing was done on the tapers. This testing, along with engineering justification, indicated that the tapers incorporated into these components are substantially equivalent to the tapers used in the predicate devices. The Hydroxyapatite coating on the Hydroxyapatite coated spindles was previously tested with porous coating, and the testing concluded that the addition of Hydroxyapatite coating did not weaken the devices tested.
Clinical Testing: Clinical testing was not required for these components to support substantial equivalence.

§ 888.3510 Knee joint femorotibial metal/polymer constrained cemented prosthesis.
(a)
Identification. A knee joint femorotibial metal/polymer constrained cemented prosthesis is a device intended to be implanted to replace part of a knee joint. The device limits translation or rotation in one or more planes and has components that are linked together or affined. This generic type of device includes prostheses composed of a ball-and-socket joint located between a stemmed femoral and a stemmed tibial component and a runner and track joint between each pair of femoral and tibial condyles. The ball-and-socket joint is composed of a ball at the head of a column rising from the stemmed tibial component. The ball, the column, the tibial plateau, and the stem for fixation of the tibial component are made of an alloy, such as cobalt-chromium-molybdenum. The ball of the tibial component is held within the socket of the femoral component by the femoral component's flat outer surface. The flat outer surface of the tibial component abuts both a reciprocal flat surface within the cavity of the femoral component and flanges on the femoral component designed to prevent distal displacement. The stem of the femoral component is made of an alloy, such as cobalt-chromium-molybdenum, but the socket of the component is made of ultra-high molecular weight polyethylene. The femoral component has metallic runners which align with the ultra-high molecular weight polyethylene tracks that press-fit into the metallic tibial component. The generic class also includes devices whose upper and lower components are linked with a solid bolt passing through a journal bearing of greater radius, permitting some rotation in the transverse plane, a minimal arc of abduction/adduction. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)

Summary of Technologies: The Hydroxyapatite coated spindles are identical in material, function, design, and sizing as the predicate spindles. The only change is the addition of Hydroxyapatite coating. The ComPreSs / OSS / Finn® Taper Adapters are made of the same material, with the same taper geometries as the predicate OSS tapers, the ComPreSs® Distal Femoral Replacement tapers, or the Finn® tapers included in the predicate ComPreSs® Distal Femoral Replacement.
Non-Clinical Testing: Mechanical testing was done on the tapers. This testing, along with engineering justification, indicated that the tapers incorporated into these components are substantially equivalent to the tapers used in the predicate devices. The Hydroxyapatite coating on the Hydroxyapatite coated spindles was previously tested with porous coating, and the testing concluded that the addition of Hydroxyapatite coating did not weaken the devices tested.
Clinical Testing: Clinical testing was not required for these components to support substantial equivalence.
