The FDA process is discussed generally in the context of the type of clearance anticipated can be obtained for the medical devices.
Devices classified by the FDA as posing less risk are placed in Class I or Class II. Class I or II only require the manufacturer to seek a 510(k) clearance from the FDA.
The clearance is generally granted when the submitted information establishes that a
proposed device is:
1. "Substantially Equivalent" in intended:
2. to a "predicate device" which is either:
Process takes from 4 to 12 months from date of submission. FDA may determine that it needs additional information or that the proposed product is precluded from receiving clearance because it is not substantially similar to a predicate device.
After clearance is received, any modifications that:
will require a new 510(k) submission.
While the devices incorporate the novel patented features, it can be strongly argued that they also utilize electrosurgical principles widely understood and are substantially equivalent to other Class I or II predicate devices already legally on the market.
If, for some chance, a device does not qualify for the 510(k) clearance it is placed into Class III, which is reserved for devices classified by the FDA as posing the greatest risk in that they are:
The PMA submission requires a more in-depth review and procedure and may take from 1 to 3 years, or longer.
A clinical trial in support of a 510(k) submission or PMA application requires an Investigative Device Exemption ("IDE") application.
A. Regular Procedure
The IDE application must be approved by the FDA:
B. Shortcut
If device presents a "nonsignificant risk" to the patients, the sponsor may begin
the clinical trial after obtaining approval for the study by one or more institutional
review boards ("IRBs") without the need for the FDA approval.
However, there is no assurance that the FDA will agree with the determinations of the IRBs and not require the sponsor to obtain the approval of the IDEs before continuing the clinical study.
Submission of the IDE application does not assure FDA will approve it, or if approved, that the FDA will determine that the data derived from the clinical studies supports the substantial equivalence or the safety and efficacy of the device or even warrant the continuation of the clinical trial.
Since the devices rely on known electrosurgical principles and operate utilizing approved electrosurgical generators, a strong argument exists that the devices present a "nonsignificant risk" to patients when compared to existing monopolar devices.
