No
The summary describes a mechanical implant (femoral head) with no mention of software, algorithms, or data processing that would indicate AI/ML.
Yes
The device is intended to reconstruct painful and/or severely disabled hip joints resulting from various medical conditions, aiming to alleviate symptoms and restore function.
No
Explanation: The device is a modular femoral head component used in hip replacement surgery; it is a prosthetic implant, not a diagnostic tool.
No
The device description clearly states it is a "modular femoral head component" and describes physical characteristics and testing (ultimate compression strength), indicating it is a hardware device, not software.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a device used in vivo (within the body) for surgical reconstruction of hip joints. IVDs are used in vitro (outside the body) to examine specimens like blood, urine, or tissue to diagnose diseases or conditions.
- Device Description: The description details a physical component implanted in the body to articulate with other components in a hip replacement. This is consistent with a surgical implant, not an IVD.
- No mention of biological samples: The text does not mention the analysis of any biological samples, which is a core characteristic of IVDs.
- Performance Studies: The performance study described is ultimate compression strength testing, which is relevant to the mechanical properties of an implant, not the analytical performance of an IVD.
Therefore, the Exeter Ceramic Femoral Heads are a surgical implant, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The Exeter Ceramic Femoral Heads are intended to be used with modular femoral components in primary and secondary cementless total hip replacement procedures. These devices are intended to articulate with a polyethylene cup or a metal backed polyethylene cup component to reconstruct painful and/or severely disabled hip joints resulting from osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, avascular necrosis, subcapital fracture, or a revision of a failed femoral prosthesis. The Exeter Ceramic Femoral Heads are intended to be used with the femoral components of the previously released Exeter hip stems - and Exeter II Total Hip System (K891454).

Device Description
This device is a modular femoral head component which is affixed to a femoral stem component and articulates with a polyethylene acetabular cup or a metal backed polyethylene acetabular cup to reconstruct painful and/or severely disabled hip joints resulting from osteoarthritis, theumatoid arthritis, post-traumatic arthritis, avascular necrosis, subcapital fracture or a revision of a failed femoral prosthesis. The Exeter Ceramic Femoral Heads described in this submission are a modification of a previously cleared Zirconia head (K972381) and Orthinox® head (K891454). The modification is a slight change in the taper angle of the device.

§ 888.3353 Hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis.
(a)
Identification. A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.(b)

510(k) Summary
Device: Exeter Ceramic Femoral Heads
This device is a modular femoral head component which is affixed to a femoral stem component and articulates with a polyethylene acetabular cup or a metal backed polyethylene acetabular cup to reconstruct painful and/or severely disabled hip joints resulting from osteoarthritis, theumatoid arthritis, post-traumatic arthritis, avascular necrosis, subcapital fracture or a revision of a failed femoral prosthesis. The Exeter Ceramic Femoral Heads described in this submission are a modification of a previously cleared Zirconia head (K972381) and Orthinox® head (K891454). The modification is a slight change in the taper angle of the device.
The substantial equivalence is based on an equivalence in intended use, materials, design, operational principles, and relative indications and contraindications to devices currently in commercial distribution including: V40™ Zirconia Femoral Heads (K972361) and Exeter II Total Hip System (K891454).
All of the named devices are intended to be used as the modular femoral head component of a total hip replacement. The basic design of these devices is generally the same, with varying diameters and lengths of internal tapers to accommodate individual patient needs. The material used in the manufacture of these femoral heads is also the same as the V40™ Zirconia Femoral Heads.
Assembly of all the named femoral head components to an appropriate femoral stem component requires similar instrumentation and preparation. All of the named Exeter Ceramic Femoral Heads are intended to articulate with the femoral components of the previously released Exeter Orthinox® (Rex 734 stainless steel) hip sterns with a 5° 43' taper. Relative indications and contraindications for all of the zirconia heads named are the same.
Testing of the Exeter Ceramic Femoral Heads included ultimate compression strength testing. All heads tested for ultimate compression strength exceeded loads greater than 46 kN as specified in the FDA Guidance Document for the Proparation of Premarket Notifications for Ceramic Ball Hip Systems.

You may, therefore, market the device, subject to the general control provisions of the Act. The general control provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls, Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (OS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
