Why control or regulate medical devices
To protect public health and safety by
- Putting devices on the market safely
- Having a mechanism to remove unsafe products
- Offering product information to consumers to allow informed choice making
What can go wrong with unregulated medical devices
- Counterfeits
- Misrepresentation/ Overstating of performance
Medical device life cycle
Three stages of Medical Device lifecycle:
Pre-market, Placing on market, Post-market
List the regulatory organizations for medical devices
WHO, GHTF > IMDRF, APEC, AHC, AWHP & Pan American Health Org
Describe a regulatory framework
A regulatory framework lists the legislation, risk classification system and regulatory body the different countries abide by.
What is risk classification for medical devices
In ASEAN/GHFT, Class A-D
In EU, Class I to III
Why the need to classify by risk?
- To ensure patient safety
- For the manufacturing process to minimize adversities
- For regulatory bodies to understand how stringent they should be on different risk devices
How to do risk classification?
Refer to: Intended Use Indication Duration of Contact Degree of Invasiveness Delivery Biological Effect
Risk Classification Rules (Flowchart Sections)
Non-Invasive
Invasive
Active
Additional Rules
What are General requirements for Essential Principles for Safety, Performance and Quality compliance for use of medical devices?
- Design and manufacture must not compromise consumer health and welfare
- Problems for risks and problems should conform to safety principles
a) foresee & identify
b) reduce & mitigate
c) add measures for unavoidable risks
d) inform users of residual risks - design, manufacture and packaging must preserve performance
- Performance of medical device under stress must not harm consumers when properly maintained
- transport and storage must not affect performance
- Benefits must outweigh risks
- Clinical evidence detailing appropriate use, risk classification, and conformity to relevant essential principles mandatory
What are the standards used for medical devices?
Basic (Horizontal), Group (Semi-Horizontal) and Product (Vertical)
What does standards used for medical devices show?
Shows the type of medical device and the requirements of that device based off risk
What is Conformity Assessment?
Systematic examination of evidence by manufacturer, as required of regulatory body to ensure safety of device, and compliance to essential principles of safety, performance and quality performed pre and post-market, as well as provides evidence of safety, risk, and performance
Elements of Conformity Assessment
Post-Market Surveillance System Quality Management System Registration of persons Registration of device Declaration of conformity Technical Documentation
What is Conformity Assessment Procedures?
Process used by manufacturers to demonstrate compliance to essential principals
What is QMS on the factory floor?
QMS is a management system that directs and controls an organization’s product quality, including the organizational structure, responsibility procedures, processes and resources for implementing quality management.
QMS areas (company/org)
Design Manufacturing supplier management risk management complaint handling clinical data storage distribution product labelling
How to comply to a QMS as required by regulatory controls
Manufacturers must ensure the designed, manufactured and supplied MD are safe, perform as intended, and complies to regulations
What are QSR and ISO13485 standards for medical device manufacturing?
They are to ensure manufacturers consistently design, produce and place on the market medical devices that are safe, and fits the intended use.
Requirements for ISO13485 standard for medical device manufacturing
ISO13485 requires a QMS that can be demonstrated to consistently meet customer requirements and regulatory requirements
What is Good Distribution Practices (GDP)?
guidelines used for distribution and quality control to maintain quality & integrity of medical devices throughout supply chain
-ISO 13485 > GDP
requirements of GDMPDS
- Quality Management System
- Resource Management
- Buildings and Facilities
- Storage and Inventory Handling
- Products Traceability
- Handling of Complaints
- Field Safety Corrective Action (FSCA)
- Return of Medical Devices
- Destruction/disposal of Medical Devices
- Illegal and Non-conforming Medical Devices
- Internal Audit
- Management Review
- Third-Party Activity or Outsourcing Activity
What is Quality Agreement?
A written agreement establishing the responsibility and obligation between the distributor and third-party service provider
What are the steps in a medical device design and development?
- Design and development plan
- Design product
- Design for manufacturing
- Design verification
- Design validation
- Design reviews
- Design change assessment
- And Design history file
What are the requirements in ISO13485 for manufacturing?
Organization must demonstrate the ability to consistently comply to customer and regulatory requirements
Product Design Step 1
Design & Development planning:
Documentation of:
a) the design and development stages;
b) the review(s) needed at each design and development stage;
c) the verification, validation, and design transfer activities that are appropriate at each design and development stage;
d) the responsibilities and authorities for design and development;
e) the methods to ensure traceability of design and development outputs to design and development inputs;
f) the resources needed, including necessary competence of personnel
Product Design Step 2
Design input:
- To have a design so that the device’s purpose and the intended use are clear
- Use performance, safety, business economics
- Risk management includes risk management plan, results of risk assessment and risk control. It is commonly conducted according to ISO 14971
- Applicable regulatory requirements and standards
