Class 1 device classification
low to moderate risk, general controls, not to present a potential and unreasonable risk of illness or injury 510(k) submission
Class 2 device Classification
moderate to high risk, general and special controls, special labeling, human clinical trials may be needed, post market surveillance, 510(k)
Class 3 device Classification
high risk, sustains life, implanted, presents a potential for unreasonable risk of illness or injury, subject to general and special controls, premarket approval (PMA)
General Controls
Must,
register manufacturing locations with FDA,
list all marketed medical devices with FDA
manufacture devices in compliance with FDA (QSRs)
label devices in compliance with applicable regulations
submit premarket notification 510(k)
Special Controls
Special labeling requirements
conformance with FDA guidance documents
mandatory performance standards
clinical trials
post market surveillance
510(k)
“predicate device”, must provide substantial evidence to predicate devices, performs same function, intended uses are comparable, any differences do not raise safety or efficacy concerns
average 93 day clearance
(PMA)
Scientific review of safety and efficacy
involves FDA and
average 250 days for approval
license granted to market the device
involves clinical studies
Humanitarian Device Exemption
expedited pathway to market, patients with a disease or or condition that affects fewer than 8000 people per year, financial incentive for manufacturers to develop devices
Breakthrough Device Designation
Intended to treat or diagnose life threatening diseases or conditions, breakthrough technology that provides advantage over existing technologies no approved treatment or means of diagnosis exists
De Novo Classification
have not been classified and are automatically classified as class three, if no predicates then 510(k) not an option, manufacturers can request lower classifications

MDR
medical device reporting,
User facilities must report a suspected medical device-related death to both the FDA
Bench Testing
Tests per industry standards, simulates use in lab setting, environmental testing, minimum number of cycles or hours until failure for expected service life
