In this way, a well-maintained DHF can support the long-term success of medical devices, ensuring patient safety and effective device performance at every step of the way. A Design History File contains everything from the approved design plan, initial concept sketches, to product specifications, to drawings and schematics. The DHF also provides a chronological record of changes made during the design process, ensuring that any issues or concerns are identified and addressed through engineering analysis. A thorough Design History File demonstrates design traceability throughout the entire product lifecycle of the medical device, mapping each design input to a design output and recording the design review process.

From the HW point of view, it is important to document the BOM of the device in this phase. Form risk management point of view, an initial version of the risk management report is necessary. Moreover, this phase regards the freezing of the device specification and definition of the outputs of the device.

Also during the '80s, aerobics was in vogue and so brought into style Spandex leggings and headbands. Hats had already begun their decline in the previous decade and were now almost completely extinct except for special occasions. Pointed toes gave way to chisel-shaped toes in 1961 and to an almond toe in 1963. Flat boots also became popular with very short dresses in 1965 and eventually, they rose up the leg and reached the knee. After 30 years of conservative clothing styles, the '60s saw a kind of throwback to the 1920s with women once again adopting a childlike look with bobbed haircuts and progressively less modest clothing.

The British designer Vivienne Westwood produced many influential and popular collections in the early 1990s, which included outfits inspired by 18th-century courtesans and the Marquis de Sade, with rounded hips, corsets, and platform heels. The London-based designer Rifat Ozbek was also popular, particularly in New York and Milan. His youthful style, which mixed references to India, Africa, and his native Turkey with clever takes on historical clothing, was reminiscent of hippest nightclubs and the more outrageous street fashions of the time.
Qualio’s quality management platform is made to scale with medical device startups and has built-in features and templates to help manage and accelerate the product development process. In the realm of medical device development and regulatory compliance, the Design History File (DHF) plays a critical role in ensuring product quality and safety. This article has explored the concept of the DHF, its components, and its significance throughout the device lifecycle. By adopting an item-based approach for documentation and document creation, medical device software developers can enhance the efficiency, accuracy, and timeliness of their DHF management.
How is a DHF Used During and After the Development Process?
Carolina Herrera, long regarded as one of the most elegant members of the jet set, in 1981 launched a series of collections aimed at women like herself, featuring impeccably cut clothes of high quality and attractive evening dresses. Also significant are the developments in Italian fashion that happened during the period. In the course of the 1970s, as a result of its ready-to-wear industry, Milan confirmed its status as second only to Paris as a center of international fashion. The 'alta moda' preferred Rome, the base of the couturiers Valentino, Capucci, and Schön. Capitalizing on the dominant trend of anti-fashion Italy offered a glamor that had nothing to do with the dictates of Parisian haute couture. While profiting from a clearly defined style, Italian fashion was luxurious and easy to wear.
Design History File (DHF) inspection is the first step in the accreditation process, and for its success, it must be prepared and maintained from the very beginning. This could include, for instance, drawing indicating device dimensions, connecting ports, and power outlet.

In this meeting, the stakeholders will review the design and make a decision about moving forward with the development of the product. A DHF is a record of all the actions and steps involved in designing a medical device. The documentation that comes out of design control procedures is collectively called the “Design History File” or DHF. Device History Record (DHR) represents the production process of medical devices and must demonstrate the fulfillment of the Device Master Record (DMR). In America three of the most influential fashion designers of the time were Michael Kors, Marc Jacobs, and Calvin Klein.

These documents collectively demonstrate that the medical device has been designed, developed, and validated according to the appropriate regulations and standards. Clearly, a Design History File is key to successful product development and regulatory compliance. It is essential for documenting all the decisions and processes that went into the design of a medical device, as well as any design and development changes that happen after launch.
These tools enable proactive quality management and continuous improvement of the DHF. Striving for FDA compliance means aligning the DHF with Quality System Regulation (QSR) elements. Developers must continuously update this file during a device's lifecycle, concisely capturing design changes, to uphold the highest levels of patient safety and product quality. Software-related documentation includes the design of the device, how to implement that design, how the device was tested, how any potential hazards were identified, risk management practices, and provides traceability. Design validation refers to all testing done to ensure the user needs are met by the final finished medical device. This type of testing will prove that the intended use is appropriate and there is a clinical use for the device.
In the pediatric example, the design validation would test whether the device can be used for pediatric patients. User needs refers to the parameters a user needs for a device to be successful in the market. Typically user needs are more broad and the specifics feed into the design inputs. For example, a User Need could be “designed for use in pediatrics.” To meet that User Need, the manufacturer will develop a series of design inputs that will make the user need “pediatric use” possible. The Design History File (DHF) is a collection of documents that outlines the design history of a medical device. The decade began with a continuation of the hippie look of the late 1960s, with kaftans, Indian scarves, and floral-print tunics.
Instead of assembling, photocopying, and perpetually updating a physical file folder with hundreds of pages, medical device companies can produce and update one document for their DHF that references the documents in the QMS. With Greenlight Guru QMS, creating and maintaining a DHF is so easy, it's practically done for you. The group of designers known as the 'Antwerp Six' (so named because all of them were graduates of the Royal Academy of Fine Arts in Antwerp), who first emerged in the 1980s, came to prominence in the 1990s. Three of the most influential of the group were Ann Demeulemeester, Dries van Noten, and Walter Van Beirendonck. Ann Demeulemeester, from her first collection in 1991, demonstrated a great deal of confidence and inventiveness.
For software, the FDA document "Content of the Premarket Submissions for Software Contained in Medical Devices" also gives you more information about the contents of the Design History Files. You could get 483 observations or be told you can’t sell the product until your DHF is fixed. Poor documentation is always at the top of the list of issues for warning letters and 483s. Keeping traceability up-to-date can otherwise take several hundred hours out of your year. Many companies we’ve spoken to have saved hundreds of hours by using Greenlight Guru throughout their project.
With the cloud-based solution, teams can easily collaborate and design high-quality products while remaining compliant with FDA and ISO regulations. If you are looking for expert assistance in creating your Design History File or require further guidance on software development in the medical device field, schedule a free consultation with an HTD Health SaMD expert. The HTD team is here to support you throughout the entire process while ensuring regulatory compliance and highest quality of end products.
If you’re lined up for an inspection, you could get into trouble with FDA if it’s not updated. Design control records must support that, and if you don’t keep up, it will end up very fragmented. Companies often throw in more business-related items, such as cost studies or competitor analyses, but these are not necessary. Regulatory changes often necessitate revisions to documentation processes, demanding flexibility from the DHF management strategy. The item-based approach allows for agile adaptation to these changes, ensuring a seamless transition.
