| Clinical Evidence |
Clinical outcome data |
Peer-reviewed studies, post-market surveillance summaries, registry data, and clearly defined patient cohorts |
Evidence should identify implant design, follow-up period, sample size, complications, revision rate, and study limitations |
Check whether the evidence relates to the same indication, anatomical site, material, and fixation method |

| Clinical Evidence |
Regulatory and conformity status |
Applicable approvals, declarations of conformity, device classification, intended-use statement, and certificate scope |
Documentation must match the exact implant family, manufacturing site, intended use, and target market |
Confirm certificate validity and scope through the relevant regulatory authority or accredited certification database |
15% |
| Quality Management |
Manufacturing quality system |
Quality certificate, audit reports, nonconformance records, corrective-action procedures, and batch-release controls |
A quality system aligned with ISO 13485 is generally expected for medical-device manufacturing, with traceable corrective actions |
Audit the actual production site and verify that the certificate covers design, production, sterilization, or subcontracted processes as applicable |
15% |
| Material Safety |
Biocompatibility and material traceability |
Material certificates, chemical composition, biocompatibility assessment, supplier controls, and lot traceability |
Material selection and biological evaluation should be justified according to the implant’s contact type, duration, and intended use |
Review testing and risk documentation against the applicable ISO 10993 biological-evaluation framework |
10% |
| Technical Support |
Surgical planning and instrumentation support |
Surgical technique guides, instrument lists, sizing charts, training materials, and operating-room support policy |
Documentation should be procedure-specific, version-controlled, and supported by trained technical personnel |
Request a sample planning session and confirm training availability without relying on unsupported clinical claims |

| Technical Support |
Response and complaint handling |
Service-level agreement, escalation contacts, complaint workflow, field-safety notification process, and response-time records |
Written acknowledgement within one business day for urgent technical or safety issues, with documented escalation and closure records |
Test the support process with technical questions and review anonymized complaint or corrective-action examples |

| Customization |
Design and engineering capability |
CAD workflow, design-control procedure, tolerance capability, finite-element analysis approach, and design-review records |
Custom designs should pass documented requirements review, risk analysis, verification, validation, and change control before release |
Ask for a redacted design-history example and confirm ownership of drawings, specifications, and change approvals |

| Customization |
Prototype-to-production transition |
Prototype validation plan, production-equivalence statement, inspection reports, sterilization plan, and packaging validation |
The released production process should be equivalent to the validated process, with defined acceptance criteria and lot release controls |
Compare prototype and production specifications, inspect first-article records, and verify packaging and sterilization documentation |
5% |
| Supply Reliability |
Capacity, continuity, and lead time |
Capacity plan, critical-subcomponent list, average lead-time history, business-continuity plan, and inventory policy |
Lead times should be documented rather than promised verbally, with contingency plans for critical materials and process interruptions |
Compare quoted lead times with historical delivery data and assess the effect of single-source materials or subcontractors |
