Intended Use
The CONSERVE® Thin Shells are intended for use in cementless total hip arthroplasty for reduction or relief of pain and/or improved hip function in skeletally mature patients. Indications for Use - non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis, 1. ankylosis, protrusio acetabuli, and painful hip dysplasia; - inflammatory degenerative joint disease such as rheumatoid arthritis; 2. - 3. correction of functional deformity; and, - revision procedures where other treatments or devices have failed 4. The CONSERVE® Thin Shell is intended for cementless hip arthroplasty.
Device Description
Design features of the shells are summarized below: - Monoblock acetabular cup . - . Available in 12 sizes - Manufactured from CoCr alloy with a CoCr porous bead coating . The CONSERVE® Thin Shells are identical to previously cleared devices, except that the subject device does not possess HA coating. Additionally, the CONSERVE® Thin Shells were evaluated via post-impaction analysis of clearance, form and frictional torque. A review of these results indicates that the CONSERVE® Thin Shells are equivalent to predicate devices.
More Information

Not Found

No
The document describes a mechanical implant and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.

Yes
The intended use statement explicitly states that the device is for "reduction or relief of pain and/or improved hip function," which aligns with the definition of a therapeutic device.

No.
The device is an acetabular shell intended for use in cementless total hip arthroplasty to treat various hip conditions, not to diagnose them.

No

The device description clearly states it is a physical implant (Monoblock acetabular cup manufactured from CoCr alloy) intended for surgical implantation, not a software product.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states the device is for "cementless total hip arthroplasty for reduction or relief of pain and/or improved hip function in skeletally mature patients." This describes a surgical implant used in vivo (within the body) to treat a physical condition.
  • Device Description: The description details a "Monoblock acetabular cup" made from CoCr alloy with a porous bead coating. This is a physical implant designed to be surgically placed in the hip joint.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (like blood, urine, or tissue) in vitro (outside the body) to provide information about a physiological state, health, or disease.

IVD devices are used to perform tests on samples taken from the body to diagnose, monitor, or screen for diseases or conditions. This device is a surgical implant used to replace a damaged hip joint.

§ 888.3330 Hip joint metal/metal semi-constrained, with an uncemented acetabular component, prosthesis.

(a)
Identification. A hip joint metal/metal semi-constrained, with an uncemented acetabular component, prosthesis is a two-part 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 consist of a femoral and an acetabular component, both made of alloys, such as cobalt-chromium-molybdenum. The femoral component is intended to be fixed with bone cement. The acetabular component is intended for use without bone cement (§ 888.3027).(b)
Classification. Class III.(c)
Date PMA or notice of completion of PDP is required. A PMA or a notice of completion of a PDP is required to be filed with the Food and Drug Administration on or before May 18, 2016, for any hip joint metal/metal semi-constrained prosthesis with an uncemented acetabular component that was in commercial distribution before May 28, 1976, or that has, on or before May 18, 2016, been found to be substantially equivalent to a hip joint metal/metal semi-constrained prosthesis with an uncemented acetabular component that was in commercial distribution before May 28, 1976. Any other hip joint metal/metal semi-constrained prosthesis with an uncemented acetabular component shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.

Dear Mr. Paul:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set
