Yes
The device is a shoulder replacement system intended to relieve pain and improve function in patients with severe shoulder conditions, which aligns with the definition of a therapeutic device.

No

Explanation: This device is a shoulder prosthesis intended for surgical implantation to replace a damaged shoulder joint. It is a therapeutic device, not a diagnostic one.

No

The device description clearly describes physical components (baseplates, stems, screws) used in shoulder arthroplasty, which are hardware.

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

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Description: The text describes a shoulder replacement system, specifically components like baseplates and humeral stems, which are implanted into the body during surgery.
  • Intended Use: The intended use is for surgical procedures (total shoulder arthroplasty) to replace damaged shoulder joints and improve function. This is an in-vivo application, not an in-vitro test.

The device is a surgical implant, not a diagnostic test performed on samples outside the body.

Summary of Technologies / Substantial Equivalence

The new components, Full Wedge Lateralized and Augmented Baseplates, are identical to the primary predicate, half wedge lateralized augmented baseplates, on indications, material, manufacturing, packaging, single use, sterilization, shelf life, biocompatibility, compatible components. The subject device is a design modification of the primary predicate that do not raise different questions of safety and effectiveness and is substantially equivalent to the primary predicate.

Non-Clinical Testing

Bench testing for glenoid loosening (ASTM F2028-17) was performed and found to be substantially equivalent to the primary predicate. Range of motion analysis has been completed based upon the same parameters and assumptions as the ROM analysis previously submitted for the primary predicate and demonstrates substantial equivalence as well as exceeding ASTM F-1378-18.

Clinical Testing

Clinical testing was not necessary to determine substantial equivalence of the Full Wedge Lateralized and Augmented Baseplates to the predicate device.

Summary

Based upon the assessment of substantial equivalence regarding the indications, material, packaging, single use, sterilization, shelf life, pyrogen testing, biocompatibility, and the nonclinical testing and assessment of the risk associated with the design modification of the primary predicate submitted here, the Full Wedge Lateralized and Augmented Baseplates are expected to be as safe, as effective, and perform as well as the legally marketed device predicate.
