CONSENSUS ACETABLAR SHELL, TI COATED

• K Number: K020153
• Device Name: CONSENSUS ACETABLAR SHELL, TI COATED
• Manufacturer: HAYES MEDICAL, INC.
• Date Cleared: 2002-04-15 ( 89 days)
• Product Code: LPH
• Regulation Number: 888.3358

Intended Use

The Ti coated porous acetabular shell is design for use with the Consensus® or UniSyn ® Hip Systems, and is not intended for substitution with components of other systems. The device is intended primarily for uncemented, press-fit applications. The indications for use are: With Consensus® System: 1. Primary intervention of rheumatoid arthritis, osteoarthritis, post traumatic arthritis or degenerative arthritis, and avascular necrosis with a non-acute fracture of the femoral neck. 2. Osteoarthrosis involving femoral and acetabular articular surfaces. 3. Avascular osteonecrosis and/or non-union of acute femoral neck fractures. 4. Fracture or dislocation of the hip. 5. Replacement of unsatisfactory cemented or press fit hip components if sufficient bone stock exists. With UniSyn ® System: 1. Significantly impaired joints resulting from rheumatoid, osteo, and post-traumatic arthritis. 2. Revision of failed femoral head replacement, hip arthroplasty or other hip procedures. 3. Proximal femoral fractures. 4. Avascular necrosis of the femoral head. 5. Non-union of proximal femoral neck fractures. 6. Other indications such as congenital dysplasia, arthrodesis conversion, coxa magna, coxa plana, coxa vara, coxa valga, developmental conditions, metabolic and tumorous conditions, osteomalacia, pseudarthrosis conversion, and structural abnormalities. 7. Indications for the use of the UniSyn Hip System must be carefully considered with respect to the patient's entire evaluation and alternative procedures. Patient selection is dependent on age, general health, available bone stock and quality, and any prior surgery or anticipated future surgery. Prosthetic replacement is generally indicated only for patients who have reached skeletal maturity. Total joint replacement in younger patients should be considered only when explicit indications outweigh the associated risks of the surgery and modified demands regarding activity and joint loading are assured. This includes all patients who may or may not have multiple ioint involvement, for whom restoration of ioint mobility leads to an expectation of greater mobility and an improvement in the quality of life.

AI/ML (Artificial Intelligence / Machine Learning)

No
The document describes a physical medical device (an acetabular shell) and its intended use in hip replacement surgery. There is no mention of software, algorithms, or any computational technology, let alone AI or ML.

Therapeutic

Yes.
The device is an acetabular shell used in hip systems to treat various medical conditions like arthritis, avascular necrosis, and fractures, which falls under the definition of a therapeutic device designed to cure, mitigate, treat, or prevent disease.

Diagnostic

No
The device is an acetabular shell intended for hip replacement, which is a therapeutic intervention, not a diagnostic one. Its purpose is to replace parts of the hip joint in patients with various conditions, not to identify or characterize diseases.

SaMD (Software as a Medical Device)

No

The device description explicitly states "Acetabular Shell, Porous Ti TI Coating," which describes a physical implant, not software.

IVD (In Vitro Diagnostic)

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

• IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
• Device Description and Intended Use: The provided text describes a Ti coated porous acetabular shell, which is a component of a hip replacement system. Its intended use is for surgical implantation to replace damaged parts of the hip joint.
• Lack of Diagnostic Activity: The device itself does not perform any tests on biological samples to diagnose a condition or provide information about a patient's health status. It is a physical implant used in a surgical procedure.

Therefore, based on the provided information, this device falls under the category of a surgical implant or prosthetic device, not an In Vitro Diagnostic.

Regulation Number and Section

§ 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)
Classification. Class II.
