  3. Inbrief In new medications, the FDA's clearance procedure is designedtoprovideconsumersconfidence thata medicaldevicewillbesafeandeffectiveinits intendeduseonceitcomestomarket. The typical time it takes to get a device to market is 3 to7years,comparedto12yearsforpharmaceuticals.

  4. However,thereareconcernsthattheFoodandDrugAdministration's SystematicReviewWritingmethodsmay notbeadequatetosatisfythe requiredguaranteesofsafetyandefficacy. This blog aims to review the second part of a two-part series on the essential phases in medical device development and FDAclearance and summarise post-marketing protocols for pharmaceuticals and devices (J Am Coll Cardiol Basic Trans Science 1:277–87, 2016). The Authors, 2016.Elsevier represents the AmericanCollegeofCardiologyFoundation. The second part of a two-part series discusses the fundamental phases in medicaldevicedevelopmentandFDAclearanceandthepost-marketing processesformedicationsanddevices.

  5. Introduction The FDA'sCenter forDevices and Radiological Health (CDRH) oversees deviceregulation. A device is defined as "an apparatus, instrument, contrivance, implement, machine, implant, or in vitro reagent" that meets three criteria: 1)itis recognisedintheofficialNationalFormularyortheUnitedStates Pharmacopeia; 2) it is intended for use in the diagnosis of disease or other conditions,orthecure,mitigation,treatment,orpreventionofdisease;or3) itisintendedtoaffectthestructureorutilityofthehumanbody.

  6. Devices cannot achieve their goals by chemical action or by metabolism. Some biologically based products are inert (e.g., acellular dermatologic fillers)andclassifiedasdevices. AccordingtotheFDA,medicaldevicesincludetonguedepressors, stethoscopes, lab equipment, surgical tools, and life-support equipment, includingpacemakers,ventilators,andperfusionsystems. Ifa product is a device or a biological, the FDA's Device Determination Officercanhelp.

In Conductinga Systematic Review, they create or arrange to construct a preliminaryprototypeofthedevicewhilealsostartingthepatent procedure.

  9. Animal testing follows initial bench testing, and the device then enters a testing and redesign cycle that takes 2 to 3 years and costs between $10 millionand$20million. Because of these expenditures, venture-backed startup firms rather than universitymedical institutesnowproducethemajorityofreally novel medicaldevices.

  10. BasicPathwaysto MedicalDeviceApproval Depending on the type of the item and the conditionsunderwhichapprovalis requested,thereare3mainstagesfor obtainingFDAmarketingclearancefor medical devices: Threeprocesses are: 1) thePMA,2)thePMN,and3)the humanitariandeviceexemption(HDE).

  11. PATHWAY1:PRE-MARKETAPPROVAL(PMA) Federal law requires device makers to inform the FDA of their intent to commercialiseamedicaldeviceatleast90daysbeforerelease. The FDA requires a PMA for every new device for which there is no existing equivalent or predicate unless the device can be classed as a "de novo" device. A device must be proven to have enough scientific Systematic Review Serviceevidence that it is safe and effective in its intended application to receiveaPMA.

  12. PATHWAY2:PRE-MARKETINGNOTIFICATION(PMN):THE510(K)APPLICATION A PMN,also known as a 510(k) application, is a fast-track process for medical devicesin which the sponsor demonstrates that the product is substantiallyidenticaltoanauthorisedandmarketeditem. Devices under PMA evaluation but not yet authorised cannot be used as a predicate device in a PMN for a separate, new device. A PMA application is notrequirediftheFDAdecidesthatthedevicehasanacceptable predicate,andPMNcanproceed.

  13. PATHWAY3:THEHUMANITARIANDEVICEEXEMPTION(HDE) Ahumanitarianusedevice(HUD)isamedicalgadgetdesignedtotreator diagnose illnesses that affect less than 4,000 people in the United States eachyear.

  16. Conclusion Drug and device approval processes have a great deal in common. Each offers unique pre-submission prospects for FDA engagement. There are three basicroutestoapprovalforeach. Amajorroad(the InvestigationalNewDrugApplicationand thePMA, respectively) requires strong clinical proof of effectiveness and safety and a channel for an emergency usage (the emergency investigational new drug andtheEmergencyUsenotification,respectively). The investigator faces a series of challenges, the first of which is to choose whichpathtotake.EarlyandregularengagementwiththeFDAis recommendedtominimiseerrorsanddifficultiesthatwastetimeandmoney.
