Planning & Regulatory Strategy

Establish regulatory pathway and project foundation

1. Determine Regulatory Pathway

Medical laser systems can follow different FDA pathways depending on intended use, risk, and predicate devices:

510(k) Premarket Notification

For devices substantially equivalent to a legally marketed predicate device. Most Class II laser systems.

  • Requires demonstration of substantial equivalence
  • Typically 90-day review (may be longer)
  • Use eSTAR template for submission
Learn More
PMA (Premarket Approval)

For Class III devices or novel devices without predicates. Higher risk laser systems.

  • Requires clinical data demonstrating safety and effectiveness
  • Typically 180-day review (often longer)
  • More comprehensive submission requirements
Learn More
IDE (Investigational Device Exemption)

For clinical investigations of unapproved devices or new indications.

  • Required before clinical studies for PMA devices
  • Allows use in clinical investigation
  • Requires IRB approval and informed consent
Learn More

2. Identify Applicable Regulations

Medical laser systems must comply with multiple FDA regulations:

Core FDA Regulations
  • 21 CFR 820 – Quality System Regulation
  • 21 CFR 801 – Labeling requirements
  • 21 CFR 830 – Unique Device Identification
  • 21 CFR 803 – Medical Device Reporting
  • 21 CFR 812 – IDE requirements
Laser-Specific Regulations
  • 21 CFR 1002 – Records and reports for radiation-emitting products
  • 21 CFR 1040 – Performance standards for light-emitting products (laser products)

3. Identify Applicable Standards

Medical laser systems must comply with multiple standards:

Electrical Safety
Laser Safety
Software
Usability
Labeling
Packaging / Sterility
  • • ISO 11135 - EO sterilization
  • • ISO 11607-1, -2 - Packaging
  • • ASTM D4169 - Shipping testing
  • • ASTM F1980 - Accelerated aging

4. Establish Project Team

Assemble a cross-functional team with expertise in:

  • Regulatory Affairs: FDA submission strategy and requirements
  • Laser Engineering: Optical design, laser physics, beam delivery
  • Electrical Engineering: Power systems, control electronics, EMC
  • Software Engineering: IEC 62304 compliance, cybersecurity
  • Usability Engineering: Human factors, user interface design
  • Quality Engineering: Risk management, design controls, testing
  • Clinical Affairs: Clinical evaluation, use scenarios
  • Manufacturing: Production processes, supplier management
