Implantable Electronics & Neurodevices worked example

Packaging Integrity Yield at 71% target packaging integrity yield: a worked example in implantable electronics & neurodevices

This worked example runs the packaging integrity yield numbers for a tougher week than the baseline: 71% target packaging integrity yield instead of the typical 99%. Calculate sterile barrier packaging integrity yield for implantable devices after seal, visual, dye, burst, or leak testing.

The inputs for this scenario

  • Sterile barrier packages passing seal integrity tests: 390 packages (held at the documented default)
  • Sterile barrier packages submitted for integrity testing: 400 packages (held at the documented default)
  • Target packaging integrity yield: 71 % (the input this scenario stresses; the baseline uses 99)

Working through the calculation

  • The calculation starts from the formula this tool documents: Packaging integrity yield = sterile packages passing integrity checks ÷ sterile packages tested × 100.
  • Packaging integrity yield works out to 97.5 % at these inputs, and this is the headline figure for the scenario.
  • Packaging integrity yield gap to target works out to -26.5 points at these inputs.
  • Sterile packages passing integrity checks works out to 390 count at these inputs.
  • Sterile packages tested works out to 400 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target packaging integrity yield sits at 99% and the headline result is 97.5 %, this scenario lands almost exactly on the baseline at 97.5 %.
  • Use it during pouch and tray sealer validation, on incoming material lot acceptance, and on routine in-process or release sampling of sealed sterile barrier systems. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Packaging integrity yield: 97.5 % (headline result)
  • Packaging integrity yield gap to target: -26.5 points
  • Sterile packages passing integrity checks: 390 count
  • Sterile packages tested: 400 count
