User needs (also known as customer attributes) 2. There are two common types of validation. This SOP applies to all medical devices that are approved for Product Development as well as to the personnel who are responsible for implementing Design Controls for such medical devices. When it is a more qualitative evaluation and can be conducted by a design … Yet, many product development teams are not always able to distinguish a user need from a design input. “Design History File” (DHF) means a compilation of records which describe the design history of a finished device. JavaScript seems to be disabled in your browser. For European CE Marking, the regulatory requirements for a device can be found in Annex I of the MDD. Design Requirements 3. Design Input: Assay Y shall have a maximum CV of 5% and be accurate within +/- 0.5 mg when the analyte concentration is between 5 and 100 mg. Summing it up, it is important that product development teams develop a good understanding of the difference between user needs and design inputs. The FDA investigator should not be inspecting a device under the requirements of design controls to determine whether the design was appropriate or safe and effective. Design Input: Assay Y shall have a maximum CV of 5% and be accurate within +/- 0.5 mg when the analyte concentration is between 5 and 100 mg. Summing it … Having customers do unnecessary testing can be costly in terms of time and money to the manufacturer and the customer. Skip to the beginning of the images gallery, Quality Documents and Templates, BAIO UG, 82299 Türkenfeld, Germany, 21 CFR Part 820 - Quality System Regulation, Subpart C - Design Controls, 820.30 Design controls, ISO 13485:2016: Medical Devices - Quality management systems ¬Requirements for regulatory purposes, FDA/CDRH - Design Control Guidance for Medical Device Manufacturers, March 11, 1997. The requirements are the most critical aspect of the overall medical d… This creates a burden on the manufacturer to then demonstrate that they have not only verified the design inputs but also have their customers validate all the specifications written into user needs prior to regulatory approval. The design input requirements shall be … Would like to hear what are some of the best practices as to writing User Needs and Design Input requirements. FDA 21CFR820.30 requires "a manufacturer to establish and maintain procedures to ensure that the design input requirements relating to a device are appropriate and address the intended use of the device, including the needs of the user and patient." It is critical that manufacturers clearly define what is a user need, what is a design input, and how the design inputs are traceable to the user needs. Like other industries, Medtech innovation starts with analyzing and identifying the market, the need of which is untapped or unmet or there is a more efficient way to address those particular needs. First, convert your essential requirements into design inputs. The quality system requirements for design output can be separated into two elements: Design output should be expressed in terms that allow adequate assessment of conformance to design input requirements and should identify the characteristics of the design that are crucial to the safety and proper functioning of the device. User Need: The customer (test ordering clinician) wants the assay to produce precise and accurate results within the clinical measuring range. Definitions relevant to medical device design control. Design Changes: Examples and Requirements. 6 of 21 The FDA investigator would usually be most interested in the devices of highest risk, but the investigator’s decision may be affected by whether a device has been subject to one or more recalls and/or MDRs. These needs could be anything that delivers a solution such as a new or better way of monitoring health, enhanced care delivery solutions, devices or technologies to deliver better administration or anything that supports health and a human life.These … Process validation uses objective evidence to make sure a process consistently produces the same result. Medical device design validation. Design Controls begin after concept and feasibility studies are completed after the COMPANY Management approves the initiation of a Product Development Project. Section 820.30(c) of the FDA guidance says: Each manufacturer shall establish and maintain procedures to ensure that the design requirements relating to a device are appropriate and address the intended use of the device, including the needs of the user … Each manufacturer of either a class II or class III medical device (as well as a select group of class I devices) needs to establish and document procedures on the design and design requirements. Design and development for medical devices has to deal with relevant regulations, product safety, and risk controls on product defects in addition to the usual application requirements, specification requirements, and end customer needs. a) FDA 21 CFR 820.30. Depending on the item being verified, a test case or test suite would be run, or an inspection or … Design Inputs uncovered - requirements, risks and regulations Requirement management is considered a key discipline in medical device development. Whereas, the design inputs describe the solution or product that address the needs of the customer. The design inputs are written in a way the manufacturer can demonstrate that they are traceable to the user needs and that the final product specifications can be verified to meet these requirements. Sandra Shefelbine researched design methodogy at the Cambridge Engineering Design Centre and this work-book is based on her master's thesis, "Requirements Capture for Medical Device Design." 14 General Requirements 21CFR 820.30(a) 15. The design and development process for medical devices is not as simple as in other manufacturing or service industries. II. Verification can use tools such as regular examination, tests and inspections. From the FDA design control guidance: "Design input is the starting point for product design. The starting point of these stories should be the voice of the customer. Sources for Design Inputs can be: 1. For user needs, the team should come up with a series of user stories based on the voice of the customer that describe who the user is, what the user wants to do, and why. Design validation, on the other hand, ensures that the device meets user needs and intended uses and will therefore become a viable product in the marketplace. Design input requirements should be comprehensive. Design Input: Instrument X is less than 2 feet in length, 1 1/2 feet in width, and 1 feet high and weighs less than 40 pounds. 3          Regulatory basis, reference documents, 4          Responsibility and accountability, 4.4      Project Leader (PL) / Head of Engineering (HE), 7.2      Design Input - User Requirements, 7.3      Design Input - Product Requirements, 7.4      Approving Design Input Documents, 8          Attachments (3 pages)  Product Requirements Specification Form, 10       Health, safety and environmental considerations, Address Quality Documents and Templates, BAIO UG, 82299 Türkenfeld, Germany. Requirements for Design Controls 13 14. If you are developing a Class II medical device for a 510(k) submission to the FDA, special controls guidance documents will include design inputs. The requirements which form the design input establish a basis for performing subsequent design tasks and validating the design. The FDA's Design Control Guidanceis helpful here. Here is the official FDA Design Controls regulation pertaining to Design Inputs, as found in 820.30(c):ISO 13485:2003 also covers this topic in section 7.3.2 Design & Development Inputs:Just by reading what FDA and ISO have to say about Design Inputs, you can see there are several terms used interchangeably when referring to Design Inputs: 1. The team should keep in mind that the user needs are written in terms of a problem that the customer wants to solve and upon receiving the solution is able to validate that the right solution was built by the manufacturer. The requirements which form the design input establish a basis for performing subsequent design tasks and validating the design. These needs aren’t always obvious to the target user, as common problems are often regarded as inconveniences that must b… If you are developing a Class IIa, Class IIb, or Class III medical device for CE marking , there is probably an ISO Standard that lists functional, performance, and safety requirements for the device. That is, the manufacturer built the product right. The design control requirements of Section 820.30 of the regulation apply to the design of Class II and III medical devices, and a select group of Class I devices. This Design Controls SOP does not apply to medical devices in very early stage of development such as early concept or feasibility stages. Design inputs have been described by the FDA as the most important part of the entire design control process. This Standard Operating Procedure (SOP) describes the Design Input which is part of the Design Control process by which the activities associated with the planning, design, and development of a new medical device are controlled and documented. One example of a design input is that the catheter outer diameter must be no larger than a previous design that is an 8 French catheter. Design Input Requirements 4. And without a strong foundation, bringing a new product to market can be problematic. Medical device design inputs and outputs are your friend. At a high level, this regulation requires: Design and development planning; Design input, including intended use and user needs (also known as customer attributes) All aspects of the medical device should be captured and defined within the list of design inputs. [citation needed] Design output - … Technical documentation needs to be in compliance with the Medical Devices Directive (MDD) 93/42/EEC or the Active Implantable Medical Devices Directive (AIMDD) 90/385/EEC (referred to … This is especially true in the medical device industry. This Standard Operating Procedure (SOP) describes the Design Input which is part of the Design Control process by which the activities associated with the planning, design, and development of a new medical device are controlled and documented. Furthermore, per design control procedures, manufacturers are required to verify that the design outputs meet the design inputs and validate that the product meets the user needs and the intended use. Verification that design output meets the design input requirements is important. The FDA also defines the requirements for the design input. It is important to understand when such a change is considered a significant design change because the regulatory authorities and notified bodies usually have to be informed of significant design changes and the device usually has to be re-authorized. For the best experience on our site, be sure to turn on Javascript in your browser. When such verification involves calculations or other engineering methods, it is carried out as a design verification activity. Call them what you want (design inputs, design requirements, design and development inputs, etc. Ward and others published Requirements capture for medical device design | Find, read and cite all the research you need on ResearchGate For this reason, medical device developers should define clear, measurable, and objective Design Inputs, that aid medical device development down the line. Another possible design input is that the catheter outer diameter must be less than a competitor product. The example below compares a user need versus a design input for an assay and hardware example: User Need: The customer (lab technician) wants to be able to operate the product on an average sized lab bench. Medical Device Regulation Thursday, December 11, 2014. The foundation of any product development process is the design inputs or design requirements to build a product. This stage is very important as the better the design inputs are, the more effective and efficient the medical device will turn out to be. Conclusions • Engage early in the medical device development process. For medical devices the Design Verificationis quite important, put into simp… The competitive advantage for the medical device manufacturer of executing these suggested seven essentials is a successful medical package design. A design change is a change in the design of a device. First, let me spend a few minutes on providing some background on Design Inputs. This website use cookies to ensure you get the best user experience on our website. All aspects–including packaging, labeling, and instructions for use. Because there could be multiple problems that need to be addressed or multiple users the product touches, there may be a need for multiple user stories. Wording User Needs or Design Inputs can be challenging but do not have to be. • Gather package design input from multiple relevant sources. • Prototype your package system design. The needs of the user are written in a manner that describes the problems that the customer or patient needs addressed rather than describe the product. She is now at Stanford University studying for a PhD. However, in order to get to the design inputs, it is necessary to have the user needs defined. In this article, we will elaborate on the medical device specific aspects of requirement management and how the concepts of intended use, regulations and risk management become an integrated and Dr John Clarkson is a University Reader in Engineering Design and Director of the Cambridge After defining user needs, understanding how to develop and document design inputs and outputs is the critical quality task in medical device design and development. Therefore, development of a solid foundation of requirements is the single most important design control activity." Design Inputs 2. There are 13 essential requirements, but there are multiple sub-parts so it may seem like more than 50 requirements. “Design Input” means the physical and performance requirements of a device that are used as a basis for device design. These design controls include: [non-primary source needed] Design input - Design inputs are typically the initial requirements that describe the medical device to be produced. PDF | On Jan 1, 2003, J. Design Verification shall confirm that the design output meets the design input requirements. Medical Device Design Input includes the features, requirements and performance criteria of a medical device. So what is the product development team to do to make sure the user needs and design inputs are written appropriately. Design inputs are supposed to be objective criteria for verification that the design outputs are adequate. Medical Device Design Inputs – The Terminology First, let me spend a few minutes on providing some background on Design Inputs. In fact, often one sees design outputs or specifications described and written into a user needs document. Design verification shall confirm that the design output meets the design input requirements, as required by 21 CFR 820.30(f). Medical devices. These requirements are written in a manner that describe the solution(s) to the problems or needs of the customer. Design inputs are the foundation of medical device development. Minimally, the design inputs describe the physical, functional, performance, interface, software, hardware, system, regulatory, and statutory requirements for the product. Design verification provides evidence (test results) that the design outputs (actual product) meet the design inputs (product requirements and design specifications). Design Input This blog talks about design input, 21 CFR 820.30(c), an important requirement of design control. It states: Each manufacturer shall establish and maintain procedures to ensure that the design requirements relating to a device are appropriate and address the intended use of … One may also see design inputs written as user needs, which may result in building the wrong product and not realizing it till the validation stage, resulting in a significant and costly redesign. Since 1990, the Food and Drug Administration (FDA) has required that medical device manufacturers that want to market certain categories of medical devices in the USA follow Design Control requirements (21 CFR 820.30). The user needs arise out of the voice of the customer and represent the need of the user and the patient and the intended use of the device. A procedure to handle design input is warranted. Therefore, development of a solid foundation of requirements is the single most important design control activity.” The requirements are the most critical aspect of the overall medical device product development effort. Verification means confirmation by examination and provision of objective evidence that specified requirements have been fulfilled. User Needs Medical Device Design Validation 97. The design inputs then describe the solutions in terms of product requirements that would address the problems the user is trying to solve in each of the user stories. 12 Design Controls (21 CFR 820.30) a) General requirements b) Design and development planning c) Design input d) Design output e) Design review f) Design verification g) Design validation h) Design changes i) Design transfer j) Design history file 13. For the best experience on our site, be sure to turn on Javascript in your browser. Design inputs are typically the device requirements (both physical and performance) describing the medical device you’re going to make. The idea for new medical devices, like most new product innovations, often stems from the discovery of an unmet market need — in this case, products that can help people better monitor and manage their health, aid providers in improving care delivery, or devices that enable better treatment administration.
