Medical devices play a critical role in modern healthcare, from diagnostic tools to life-saving equipment. Bringing a new medical device to market is a complex process that requires a significant investment of time and resources. In this blog post, we will outline the key steps involved in bringing a medical device to market and the considerations that must be made at each stage.
Research and Development
The first step in bringing a new medical device to market is identifying a need for the device. This may come from observing a gap in current treatment options or recognizing an opportunity to improve upon existing devices. Once a need has been identified, market research is conducted to assess the potential demand for the device and to identify any potential competitors. Only then can a device be designed and prototyped. Companies typically provide a prototype of a medical device through a process that involves creating a physical or functional model of the device to be used for testing, evaluation, and demonstration. There are several ways that companies can create a prototype of a medical device, including:
Rapid prototyping: This method uses computer-aided design (CAD) software to create a 3D model of the device. This model is then used to create a physical prototype using techniques such as 3D printing or computer numerical control (CNC) machining. This method is quick and cost-effective, making it ideal for early-stage prototyping.
Virtual prototypes: This method involves creating a virtual prototype of the device using computer simulations. Virtual prototypes can be used to test the device’s performance and user interactions without the need for a physical prototype. Virtual prototypes are often used in the early stages of development and are useful for evaluating the design of a device before it is built.
Hand-built prototypes: This method involves creating a physical prototype of the device by hand, using materials such as plastic, metal, or wood, and is often used for early-stage prototyping to create a rough or working model of the device.
Functional prototypes: This method involves creating a working prototype of the device that can perform the same functions as the final product. Functional prototypes are often used for later-stage prototyping and can be used to test the device’s performance and usability.
Once the prototype is completed, it is then used for testing and validation, which may include both laboratory and clinical testing. Testing and validation are conducted to ensure the device meets the necessary safety and performance requirements. This process may involve collaboration with medical experts, engineers, and regulatory professionals. The prototype is often also used for demonstrations and presentations to potential investors or partners.
It is important to note that the type of prototype used will depend on the device and stage of development. For example, early-stage prototypes may be less complex and less expensive than later-stage prototypes, while functional prototypes may be more complex and more expensive than rapid prototypes.
The regulatory landscape for medical devices is complex and varies depending on the type of device and the country in which it will be sold. Understanding the regulations and standards for medical devices is crucial to ensuring compliance and obtaining clearance or approval from the regulatory bodies.
In the US, the Food and Drug Administration (FDA) is responsible for regulating medical devices. There are two main regulatory pathways for medical devices in the US, the 510(k) and premarket approval (PMA) process.
The 510(k) process is for devices that are similar to devices already on the market. This process requires the manufacturer to demonstrate that their device is substantially equivalent to a legally marketed device, known as a “predicate device.” If the FDA determines that the device is substantially equivalent, it will clear the device for commercial distribution.
The PMA process is for devices that are considered to be of higher risk, such as implantable devices or devices that support or sustain human life. This process requires the manufacturer to provide a substantial amount of data to the FDA to demonstrate the safety and effectiveness of the device. If the FDA determines that the device is safe and effective, it will approve the device for commercial distribution.
In addition, medical device companies are requested to prepare and submit a premarket submission; however, in some very specific circumstances the devices are exempt from premarket notification and can be marketed without clearance or approval from the FDA. The types of devices that are exempt from premarket notification are generally considered to be of low risk and include:
- Custom devices: Devices that are individually made for a single patient and are not intended to be commercially distributed.
- Devices that are not intended to affect the structure or function of the body, such as some diagnostic imaging equipment and some laboratory equipment.
- Devices that are similar to devices that have been legally marketed before May 28, 1976, also known as “grandfathered” devices.
- Devices that have been reclassified by the FDA as class I or class II devices and are subject to general controls only.
- Devices that are intended for veterinary use.
- Devices that are intended for export only and are not intended to be used within the United States.
It is crucial to seek guidance from professionals in the field and the FDA in order to determine if your device qualifies for exemption from premarket notification. Even though a device might be exempt from premarket notification, the device must still comply with other applicable requirements such as good manufacturing practices (GMPs) and labeling requirements. Additionally, the FDA has the authority to remove a device from the market if it is found to be unsafe or ineffective.
