ISO 13485 — Medical Device Quality Management System

Quick Answer

What is ISO 13485?
ISO 13485 is the internationally recognised quality management system (QMS) standard for organisations involved in the design, production, installation, and servicing of medical devices. It is the primary QMS standard for medical device manufacturers worldwide and is typically required for regulatory compliance with FDA 21 CFR 820 (Quality System Regulation), EU MDR (Medical Device Regulation), and other national regulations. For titanium component suppliers, ISO 13485 certification demonstrates the capability to produce machined parts consistently meeting medical device quality and traceability requirements.

Scope

ISO 13485 applies to all organisations that manufacture medical devices, including contract manufacturers of components and sub-assemblies. For titanium machine shops, the standard covers receiving inspection, machining, cleaning, passivation, packaging, and documentation processes.

Key areas of applicability for medical component manufacturers:

• Raw material receiving and verification with full MTR review
• CNC machining of implant and instrument components
• Cleaning and contamination control (including cleanroom requirements)
• Surface finishing (passivation, electropolishing per ASTM F86)
• Inspection and dimensional verification
• Packaging and labelling
• Sterilization validation support
• Complaint handling and regulatory reporting

Key Requirements

Documentation and Records

• Device Master Record (DMR) — Complete specifications, drawings, and process documentation for each device
• Device History Record (DHR) — Production records showing traceability of each production batch
• Risk Management File — Per ISO 14971 for all manufacturing processes
• Validation Records — Process validation for special processes (cleaning, passivation, packaging)
• Training Records — Documented competency for all manufacturing personnel

Design Control (If Applicable)

• Design and development planning per design control procedures
• Design reviews, verification, and validation
• Design transfer to production
• Design changes and configuration management

Purchasing and Supplier Management

• Supplier evaluation and approval criteria
• Purchasing data specifying acceptance criteria
• Verification of purchased product (MTR review, incoming inspection)

Traceability Requirements

Device Type	Traceability Level
Implantable Devices	Full lot/batch traceability with implant card
Surgical Instruments	Lot traceability recommended
Dental Implants	Full serial/lot traceability
Instrument Trays	Lot traceability for components

Cleanliness and Contamination Control

• Defined cleanliness levels for implant components
• Cleaning validation per ISO 19227 or equivalent
• Packaging validated to maintain cleanliness through shelf life
• Bioburden monitoring for sterile device components

Typical Applications

• Orthopaedic Implants: Hip and knee replacement components, trauma plates and screws, spinal implants
• Dental Implants: Implant bodies, abutments, healing screws, bar attachments
• Surgical Instruments: Cutting guides, drill guides, reamers, surgical power tool components
• Cardiovascular: Pacemaker enclosures, stent delivery system components, surgical instrument handles
• Craniofacial: Mandibular reconstruction plates, cranial mesh, orbital floor implants
• Robotic Surgery: End-effector components, instrument shafts, sterile adaptors

Related Materials

• Grade 23 Titanium (Ti-6Al-4V ELI) — Primary implant material per ASTM F136
• Grade 5 Titanium (Ti-6Al-4V) — Surgical instruments and non-implant medical devices
• ASTM F136 — Wrought Ti-6Al-4V ELI for surgical implant applications
• ASTM F86 — Standard practice for surface preparation and marking of metallic surgical implants

Related Services

• 5-Axis CNC Machining — Complex implant geometries under ISO 13485 QMS
• CNC Turning — Precision screw and cylindrical components for medical devices
• Wire EDM — Burr-free cutting of implant blanks
• Electropolishing — Medical-grade surface finish (Ra < 0.2 µm) per ASTM F86
• Passivation — Nitric acid passivation for corrosion resistance
• Additive Manufacturing (DMLS) — Custom patient-specific implants from Ti-6Al-4V ELI powder
