Device Description
Cobalt™ Bone Cement provides two separate, pre-measured sterilized components which when mixed form radiopaque rapidly setting bone cement.

The summary describes a bone cement and its physical properties, with no mention of AI or ML.

No.
The device is a bone cement used to fix prosthetic parts to bone, which is a supportive and structural material rather than a therapeutic agent.

No

Explanation: The device is Cobalt™ HV Bone Cement, indicated for use as bone cement in arthroplasty procedures to fix prosthetic parts to bone. Its purpose is to physically secure components, not to diagnose a medical condition.

No

The device description clearly states it is a bone cement formed by mixing two components, indicating it is a physical material, not software. The performance studies also focus on the material properties of the cement.

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

Here's why:

  • Intended Use: The intended use clearly states that the device is used as bone cement in surgical procedures (arthroplasty) to fix prosthetic parts to bone. This is a therapeutic and structural application within the body.
  • Device Description: The description confirms it's a material that is mixed and sets to form bone cement.
  • Lack of Diagnostic Purpose: There is no mention of the device being used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. IVDs are typically used to test blood, urine, tissue, etc., to detect diseases, conditions, or measure substances.

The information provided describes a medical device used in vivo (within the body) for surgical fixation, not an in vitro (outside the body) diagnostic test.

Summary of Performance Studies

Extensive in-vitro testing was performed in accordance with Class II Special Controls Guidance: Polymethylmethacrvlate (PMMA) Bone Cement: Guidance for Industry & FDA-July 17, 2002 to demonstrate the equivalence of Cobalt™ Bone Cement to Palacos® R Bone Cement. Test results showed that the technological characteristics (mechanical, chemical, physical & handling properties) of the two cements are substantially the same. The substantial equivalence of Cobalt™ Bone Cement to Palacos® R Bone Cement was determined by performing comparative in vitro testing and then comparing the results. The results showed that Cobalt™ Bone Cement possesses mechanical, chemical, physical and handling characteristics necessary to fulfill its intended use. No clinical testing was performed.

Proprietary Name: Cobalt™ HV Bone Cement

Common Name: Bone Cement

Legally Marketed Devices To Which Substantial Equivalence Is Claimed:

Device: Palacos® R Bone Cement Approved by: PMA (P810020, S001, S002, S003, S004) reclassified into Class II Manufacturer: Biomet Inc.; 56 East Bell Drive; Warsaw, IN 46582

Predicate Device: Generation 4® Bone Cement Cleared by: 510(k) Notification (K993836) Manufacturer: Biomet Inc.; 56 East Bell Drive; Warsaw, IN 46582 (Relevant to packaging and sterilization processes cleared for this device)

Device Description:

Cobalt™ Bone Cement provides two separate, pre-measured sterilized components which when mixed form radiopaque rapidly setting bone cement.

Materials used:

40 g powder component (copolymer):

  • Methylmethacrylate-methylacrylate copolymer containing FD&C Blue No. 2 . Aluminum Lake
  • Benzoyl peroxide, hydrous 75% .
  • Zirconium dioxide .

20 ml of liquid component (monomer):

  • Methylmethacrylate (stabilized with hydroquinone) .
  • . N.N-dimethyl-p-toluidine

Methymethacrylate monomer is the primary constituent of the liquid component. In much smaller quantities are the accelerator, N, N-dimethyl-p-toluidine, and the stabilizer, hydroquinone, both are typical constituents of PMMA bone cement.

1

When the powder and liquid components are mixed, the accelerator speeds the generation of free radicals and the stabilizer in the liquid reacts with many of the early free radicals, but is soon consumed. Free radicals can then initiate formation of polymer chains.

Polymerization proceeds slowly over the first few minutes. Polymer chains at the surface of the powder beads mingle with monomer and newly formed polymer chains, while smaller beads may dissolve completely. The cement temperature rises as set time of the cement approaches. Polymerization is essentially complete and the bone cement is hard within 15 minutes.

Intended Use / Indications for Use:

Cobalt™ Bone Cement is indicated for use as bone cement in arthroplastic procedures of the hip, knee and other joints to fix plastic and metal prosthetic parts to living bone when reconstruction is necessary because of osteoarthritis, rheumatoid arthritis, traumatic arthritis, avascular necrosis, nonunion of fractures of the femur, sickle cell anemia osteoporosis, secondary severe joint destruction following trauma or other conditions (also for fixation of unstable fractures in metastatic malignancies), and revision of previous arthroplasty procedures.

Summary of the Technological Characteristics:

Extensive in-vitro testing was performed in accordance with Class II Special Controls Guidance: Polymethylmethacrvlate (PMMA) Bone Cement: Guidance for Industry & FDA-July 17, 2002 to demonstrate the equivalence of Cobalt™ Bone Cement to Palacos® R Bone Cement. Test results showed that the technological characteristics (mechanical, chemical, physical & handling properties) of the two cements are substantially the same.

Non-Clinical:

The substantial equivalence of Cobalt™ Bone Cement to Palacos® R Bone Cement was determined by performing comparative in vitro testing and then comparing the results. The results showed that Cobalt™ Bone Cement possesses mechanical, chemical, physical and handling characteristics necessary to fulfill its intended use. In summary, Cobalt™ Bone Cement is substantially equivalent to Palacos® R Bone Cement for its primary intended use of fixation of prosthetic components as described in the device labeling. No clinical testing was performed.

Clinical Testing: No clinical testing was required.
