Answers stay in the current tab; the worksheet has no upload, account or email gate.

Question-Led Scope

Record controlled facts, missing evidence, unresolved decisions and review triggers.

What It Organises

Build the evidence map before fixing the answer

This worksheet helps a project team structure device-specific inputs and expose gaps before those inputs are used in a Biological Evaluation Plan, report, testing rationale or submission response. It does not calculate compliance or prescribe a test programme.

Prepared by Arvind Rathore, founder of MedDev Advisory and former Marie Skłodowska-Curie Early Stage Researcher at INSERM U1026 Biotis within the ImplantSens network.

Cycle map

Record every labelled cleaning, disinfection and sterilisation step.

State comparison

Compare new, processed and end-of-life configurations.

Change register

Surface, residue, durability and function-related observations.

Evidence interface

Keep reprocessing validation and biological evaluation connected but distinct.

Browser-Only Working Record

Capture the controlled state and the uncertainty

Choose the closest documented state and add only generic, non-confidential notes. Blank inputs remain visible as evidence needs in the generated record.

01 Scope boundary and labelled cycle Define the reusable-device route and the complete controlled workflow.

Distinguish manufacturer-labelled reuse from third-party processing of a single-use device.

Include point-of-use care, cleaning, disinfection, sterilisation, drying and storage.

Record generic agents, times, temperatures, equipment, rinsing, drying and handling.

02 Device, contact and maximum use Connect the processed device state to contact and lifecycle limits.

Include assemblies, lumens, hinges, coatings and surfaces after reassembly.

Use labelled maximum cycles and observable retirement criteria.

Record generic contact, duration, clinical environment and reuse frequency.

03 State comparison and change Compare what processing can leave behind or alter over time.

Identify the states represented by available evidence.

Consider detergents, disinfectants, sterilants, corrosion, wear and coating change.

Record generic discoloration, roughness, corrosion, cracking, residue, wear or loss of function.

04 Evidence and representative states Preserve the boundary between validation, biological evidence and lifecycle decisions.

Map validation, chemistry, material, performance and biological records separately.

Confirm that the test or review state can be produced and documented consistently.

Record unresolved cycle, residue, surface, representative and change-control questions.

No answer is uploaded. The generated record remains in this page until you reset or close it.

Primary References

Use the record with controlled sources

The worksheet is a navigation aid. Confirm decisions against the purchased/current standard, applicable market requirements and the device’s controlled evidence.

Related evidence resources

Does validated reprocessing automatically establish biocompatibility?

No. Reprocessing validation and biological evaluation answer connected but different questions. The worksheet records how the labelled cycle may change residues, surfaces and the patient-contacting state so that applicability can be reviewed explicitly.

Are my answers uploaded or saved?

No. The worksheet runs in the current browser tab and does not store or transmit the answers. You may print the generated scoping record or save it as a PDF using the browser print dialog.

Is the generated record a BEP, BER or regulatory conclusion?

No. It is a preliminary scoping record for structured review. It is not a Biological Evaluation Plan, Biological Evaluation Report, compliance decision, biological-safety conclusion, regulatory classification or approval.

Turn the scoping record into a controlled evidence plan

Share a generic device description and the unresolved evidence questions. I will outline the likely review scope, priorities and next step before any engagement.
