Comparing randomized controlled clinical trials between Pharmaceuticals and Medical Devices can be difficult. Although randomized controlled trials are the norm in pharmaceutical trials, these studies often involve comparators. Most studies on medical devices seals involve smaller patient populations and evaluate short-term efficacy and safety. In contrast, conformity studies are rare and powered for safety. However, because of the economics of the device industry, many manufacturers seek to bolster their devices with published data or demonstrate conformity and similarity with existing treatments.
In Vitro Diagnostics Directive
The current legal framework for in vitro diagnostics is set by the In Vitro Diagnostics Directive (98/79/EC). However, the European Commission recently proposed a “legal decree” that replaces the directive with a single, unified regulation. The new regulation will not require national acts to be transposed, and strengthens the European Commission as an independent regulator. It will also make regulation changes easier and faster in the near future.
The new EU legislation for in vitro diagnostics, the In Vitro Diagnostics Regulation, has a five-year transition period. The new EU IVDR requires manufacturers of IVD medical devices to update their Technical Documentation to meet its new regulatory expectations. This means that manufacturers of these devices have until 2022 to revise and update their Technical Documentation, a process that will be much more stringent than that under the IVDD.
To comply with the Directive, self-testing medical devices must pass an extensive safety assessment and CE marking process. Moreover, they must meet certain criteria to qualify as in vitro diagnostics for the EU Market. Ultimately, compliance with the Directive will benefit health institutions, patients, and the public. Further, it will make compliance with the directive easier. Once approved, the In Vitro Diagnostics Directive will allow EU companies to sell their medical products in EU markets.
Medical Devices Directive
The Medical Device Directive is the EU’s framework for regulating the marketing, manufacturing, and distribution of devices for human use. It specifies the essential requirements of these devices, as well as the procedures for their conformity assessment. There are different categories of these devices, depending on their level of risk and their intended use.
The proposed new rules require manufacturers of class IIa and IIb medical devices to re-evaluate their current clinical evaluations and consider the revised wording of the regulation, which addresses the equivalence approach and circumstances justifying not carrying out a clinical investigation. In general, however, the new regulations will not impact manufacturers’ economics.
The scope of the Medical Device Directive is broad and overlaps with other EU regulations. It covers all relevant hazards, including electro-mechanical safety and electromagnetic compatibility. However, it has been criticized for its lack of clarity and inflexibility. However, the European Commission says the delay will benefit patient safety and ensure that manufacturers adhere to current medical device regulations. In the meantime, this delay will allow manufacturers to respond more effectively to any shortages that might occur.
The MDR extends the medical devices regime to other products that do not have a medical purpose but have a similar risk. These include cosmetic contact lenses and skin fillers. The MDR also has rules for risk classification. Several devices, such as mobile medical apps, are reclassified in a higher risk category as a result. A new approach to ensuring safety of medical devices is essential for the industry and for consumers.
Classification of medical devices
The new EU MDR (Medical Device Regulation) has brought the classification of medical devices into line with other international regulations. Both the US and EU have similar regulatory processes, and the closer alignment of the two systems has made many aspects of these processes easier. Here are the three classes of medical devices:
Class IIb: Devices that have medium to high risks, and may be used for more than 30 days. They comprise approximately 8 percent of the market. Their control level is similar to that of Class III medical devices, but they do not require a separate CE certificate or expert panel participation. As a result, they pose the highest risk to patients, and permanent monitoring is necessary. Moreover, Class IIb devices can be classified as hazardous medical devices.
The purpose of medical device classification is to determine which regulatory requirements are required for each type. It must be consistent with the device’s claims and instructions. Otherwise, it will be deemed to have an “accepted general medical use” and regulated by the FDA. Depending on the intended use, the FDA may also issue guidelines that require device manufacturers to comply with the relevant requirements. Those documents can be helpful in determining the classification for a particular device.
Medical devices are classified by risk level. The risk level of a device depends on its intended purpose, structural characteristics, use, and status. Generally, medical devices are classified as either body-contacting or non-contacting according to the risks associated with their use. The risk level of a device depends on the intended use, its status, and whether it is a reusable or disposable device. If a medical device does not require extensive medical monitoring, it is not considered a reusable device.
Regulation of medical device marketing
A regulatory strategy defines the path to market access for medical devices, and the process for gaining access to the various regions and national markets always precedes regulatory approvals. The strategy involves identifying the elements and factors that affect the medical device and the regulatory pathway, and the cost and timeline of each step.
Although drug advertising and medical device advertising have similar requirements, regulations for medical device advertisements differ from those for drugs. The FDA requires advertising to provide an appropriate balance of benefits and risks, require specific language, and set a certain size of print. Furthermore, the regulations prohibit unsubstantiated claims about a product’s safety, efficacy, and comparability. The CDRH’s Office of Compliance has only three full-time employees dedicated to reviewing advertisements for restricted devices.
The FDA regulates the marketing and advertising of tens of thousands of medical devices.Therefore, they are classified as prescription devices. Listed below are the steps to take before submitting a marketing application.
Regulation of medical device marketing is essential to protect the public’s health and safety. Regulatory agencies publish consultation documents, announcements, fact sheets, and the MedEffect section. Depending on the intended use of the product, the government must issue a PMA or a 510(k) petition. In both cases, manufacturers must submit clinical data to support the claim. Regulatory agencies review these documents, and may require additional clinical trials or even certification by the Canadian Nuclear Safety Commission (CNS).
Human factors in medical device design
One of the pillars of the FDA’s quality system regulation is human factors. Understanding human factors in medical device design helps reduce risk while emphasizing usability. The subject encompasses practically every aspect of medical device design, from packaging and usability to safety and quality. In addition to reducing risk, good human factors design helps ensure that a product’s intended user is likely to understand its functionality and safety. It’s essential that medical device designers understand the importance of human factors in the design process.
Whether to include a human-factors effort in a medical device design depends on a variety of factors. One of these is the nature of the user-device interaction. Other considerations include user population, use environment, and likelihood of error. The company’s experience with predecessor devices can also affect decisions on human factors. The basic variables discussed in this course will help you determine whether to include human factors in the design process of a new product or a medical device.
Obtaining performance data from actual users is essential. Testing participants must use the device safely and effectively in real-world conditions. Human factors engineers should also be included in the design team. This allows them to integrate into the project design team, and ensure that the final product meets the needs of patients and healthcare providers. The size and organization of the firm will determine whether or not human factors engineers are included in the design process. If the product development team includes human factors engineers, the results should be positive.
Aside from safety, human factors in medical device design should also take into account human capabilities and limitations. Often, a medical device will fail to function properly or even be dangerous due to user errors. Human capabilities and limitations are the most basic of factors to understand and apply in medical device design. The user’s capabilities include strength, dexterity, reach, vision, and hearing. The user’s experience of a device is vital in minimizing the risk of serious errors.
