The summary describes a mechanical implant and its performance in bench testing, with no mention of software, algorithms, or AI/ML terms.
Yes
The device is an orthopedic implant for hip revision surgeries, which is inherently therapeutic.
No
The device is an orthopedic implant for hip revision surgeries, not a tool for diagnosing medical conditions.
No
The device description clearly states it is a physical prosthesis made of cross-linked UHMWPE (XLPE) and is intended for surgical implantation. It is a hardware device, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states it's for use in revision surgeries of the BIRMINGHAM HIP Resurfacing (BHR) System. This is a surgical implant, not a device used to examine specimens from the human body to provide information for diagnosis, monitoring, or compatibility.
- Device Description: The description details a prosthetic implant made of UHMWPE, designed to articulate within the hip joint. This is a mechanical device for surgical implantation.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), providing diagnostic information, or being used in a laboratory setting.
This device is a surgical implant used in orthopedic procedures.

Device Description
The BIRMINGHAM HIP Dual Mobility Insert prosthesis is a cross-linked UHMWPE (XLPE) insert intended for use in BIRMINGHAM HIP Resurfacing (BHR) System revision surgeries in cases where a BHR acetabular cup is retained and the femoral component revised. The BIRMINGHAM HIP Resurfacing (BHR) received initial PMA Approval under P040033 (05/09/2006).
The device consists of an XLPE insert component designed to articulate against the retained BHR acetabular cup. The insert is also designed to interface with Smith & Nephew femoral heads and THA femoral stems. During low level activity the articulation occurs between the femoral ball head and the insert with the insert remaining in a neutral position. During high level activities requiring a larger range of motion the femoral stem contacts the insert and articulation between the insert and shell will occur.
The inserts are supplied in 11 sizes between 38-58mm to match the core BHR acetabular cup size range.
The purpose of this 510(k) submission is to add a revision option for the BHR System in cases where an acetabular cup is retained and the femoral component revised.

§ 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)

VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE
The subject BH Dual Mobility Inserts have a similar intended use to the predicate POLARCUP Dual Mobility System implants (S.E. K110135 (S.E. 10/14/2011)). Additionally, the subject BH Dual Mobility Insert contains identical internal surface designs compared with the predicate POLARCUP XLPE Inserts as they relate to articulation against a femoral head. The subject BH Dual Mobility Insert size range is within the range of the existing POLARCUP insert sizes.
The subject BH Dual Mobility Insert is manufactured from identical XLPE material and follows an identical sterilization method as the predicate POLARCUP Dual Mobility System implants (S.E. K110135 (S.E. 10/14/2011)). Both the BH Dual Mobility Insert and the POLARCUP Dual Mobility System implants are available for use with metal, ceramic or Oxinium, 22 and 28mm femoral ball heads. Both the subject and predicate devices are manufactured, packaged and sterilized in the same locations and follow an identical manufacture process flow.
The Subject BH Dual Mobility Insert differences from the predicate POLARCUP Dual Mobility System implants consist of: The BH Dual Mobility Insert is intended for use against a fixed CoCrMo BH Acetabular cup whilst the POLARCUP Dual Mobility Insert is intended to articulate against the stainless steel POLARCUP Acetabular shell. Additionally, the BH Dual Mobility Insert is intended for use in a revision scenario for use against an insitu BHR Acetabular Cup whereas the POLARCUP Dual Mobility Insert is intended for use in both primary and revision cases against a new POLARCUP shell.
Bacterial endotoxin testing was completed and met the acceptable endotoxin limits as stated in the FDA Guidance , "Submission and Review of Sterility Information in Premarket Notification (510(k)) Submissions for Devices Labeled as Sterile," "Pyrogen and Endotoxins Testing: Questions and Answers," and ANSI/AAMI ST72.
6
Therefore, the technological characteristics of the subject device are the similar to the technological characteristics of the predicate device POLARCUP Dual Mobility System implants (S.E. K110135 (S.E. 10/14/2011)).
