Abstract Cleaning chemistries are detergent-based formulations that are used during the processing of reusable medical devices. Manufacturers are responsible for demonstrating the safety of cleaning formulations when they are used during a device processing cycle, including the risk of device-associated cytotoxicity over the concentration ranges for recommended use and rinsing during cleaning. However, no regulation currently exists requiring manufacturers to demonstrate such safety. Although manufacturers' safety data sheets (SDSs) provide information on the safe use of chemicals for users, this information may not provide sufficient detail to determine the risks of residual chemicals on device surfaces. SDSs are not required to contain a comprehensive list of chemicals used, only those of risk to the user. They should be supplemented with information on the correct concentrations that should be used for cleaning, as well as instructions on the rinsing required to reduce the levels of chemicals to safe (nontoxic) levels prior to further processing. Supporting data, such as toxicity profiles or cytotoxicity data that support the instructions for use, would provide medical device manufacturers and healthcare personnel with the necessary information to make informed decisions about selection and correct use of detergents. In the current work, cytotoxicity profiles for eight commonly used cleaning formulations available internationally were studied. Although all of these products are indicated for use in the cleaning of reusable medical devices, results vary across the serial dilution curves and are not consistent among detergent types. The information presented here can be leveraged by both medical device manufacturers and processing department personnel to properly assess residual detergent risks during processing. This work also serves as a call to cleaning formulation manufacturers to provide this information for all chemistries.

BACKGROUND While digital and data-based technologies are widespread in various industries in the context of Industry 4.0, the use of smart, connected devices in healthcare is still in its beginnings. Innovative solutions for the medical environment suffer from difficult access to medical device data and high barriers for market entry due to proprietary systems. OBJECTIVE In the proof-of-concept project OP 4.1, we show the business viability of connecting and augmenting medical devices and data through software add-ons by giving companies a technical and commercial platform for the development, implementation, distribution, and billing of innovative software solutions. METHODS The creation of a central platform prototype requires the collaboration of several independent market contenders, amongst them medical users, software developers, medical device manufacturers, and platform providers. A dedicated consortium of clinical and scientific partners as well as industry partners was established. RESULTS We demonstrate the successful development of the prototype of a user-centric, open, and extensible platform for the intelligent support of processes starting with the operation room. By connecting heterogeneous data sources and medical devices from different manufacturers and making them accessible for software developers and medical users, the cloud-based platform OP 4.1 enables the augmentation of medical devices and procedures through software-based solutions. The platform also allows for the demand-oriented billing of applications and medical devices, thus permitting software-based solutions to fast-track their economic development and become commercially successful. CONCLUSIONS The technology and business platform OP 4.1 creates a multi-sided market for the successful development, implementation, distribution, and billing of new software solutions in the operation room and in the healthcare sector in general. Consequently, software-based medical innovation can be translated into clinical routine fast, efficiently, and cost-effectively, optimizing the treatment of patients through smartly assisted procedures.

The U.S. Food and Drug Administration has recently mandated that medical device manufacturers adopt Unique Device Identification (UDI) standards on their medical devices. The benefits that UDI brings to hospitals and patients is relatively obvious, including inventory transparency, product safety, product equivalency, business intelligence. However, adoption by manufacturers, who face the mandate, has been slow in part because the benefit to them is not as readily perceived. This study focuses on the incentives, barriers, and benefits that medical device manufacturers perceive in UDI adoption. This study seeks to understand which adoption pressures are driving manufacturers to act, and attempts to gauge the benefits to manufacturers from UDI adoption. Through survey methods, the evidence suggests that medical device manufacturers implement UDI largely as a response to the coercive and normative pressures they face. There continues to be a high level of uncertainty regarding the return on investment for the medical device manufacturers, particularly from the late adopters.

And Performance

Advances in medical device technology have been dramatic in recent years resulting in both an increased number of medical devices and an increase in the invasiveness and critical function which devices perform. Two new regulations entered into force in Europe in May 2017, the Medical Device Regulation (MDR) and the In Vitro Diagnostic Device Regulation (IVDR). These regulations will replace the current directives over the coming years. These regulations, for the first time introduce requirements relating to registries. Medical device manufacturers are required to have systematic methods for examining their devices once available on the market, by systematically gathering, recording and analysing data on safety and performance. Registries can assist public health protection in very practical ways, for example, to help urgently identify patients or devices. Registries can also be powerful tools for collecting and appraising real-world clinical evidence concerning medical devices. Clinical investigations are limited in terms of the sample size and the duration of follow-up which can reasonably be expected. Registries may also be the only available tool to examine rare adverse effects, sub-populations or for time durations which it is not possible or feasible to study in a clinical investigation. By ensuring that a core dataset is collected which can be compared to other registries or trial data, it is possible to pool data to better examine outcomes. There are a range of excellent initiatives which have aimed at ensuring the appropriate regulatory application of registry data.

Key Words Biocompatibility

BACKGROUND Biomaterial is defined as "any substance or combination of medicine, artificial or natural origin, which can be used at any time, in whole or part by a system that controls, adds to, or restores any tissue, organ or function". ISO 10993-1: 2018 standard defines bio compliance law as "the ability of a medical device or tool to perform a selected program with the acceptable response of experts". Incompatible factors cause chemical reactions in patients, with little or no side effects. The body can respond in a sort of way after the installation of medical devices, so testing and improvement is important here. Therefore, testing and improvement in this field are important. Biocompatibility is required for any significant use of components or materials in medical devices. Inconsistent factors create negative biological responses in patients, which may have serious consequences. Biomaterials are substances utilized in medical devices, especially in applications where the device is touched, temporarily embedded, or permanently implanted within the body. Because of the significant impact of biocompatibility, many countries have imposed regulations on medical device manufacturers to meet biocompatibility specifications. Here is a brief explanation about the biocompatibility and incompatibility parameters of medical devices with a human body and its need for biocompatibility of medical devices with the human body. Medical devices have improved doctors' ability to diagnose and treat disease, which has led to significant improvements in health and quality of life. Thus, medical devices are prone to various incompatibility issues and procedures that affect the biological environment must be followed.

Monocyte activation tests (MAT) are widely available but rarely used in place of animal-based pyrogen tests for safety assessment of medical devices. To address this issue, the National Toxicology Program Interagency Center for the Eval­uation of Alternative Toxicological Methods and the PETA International Science Consortium Ltd. convened a workshop at the National Institutes of Health on September 18-19, 2018. Participants included representatives from MAT testing laboratories, medical device manufacturers, the U.S. Food and Drug Administration’s Center for Devices and Radio­logic Health (CDRH), the U.S. Pharmacopeia, the International Organization for Standardization, and experts in the development of MAT protocols. Discussions covered industry experiences with the MAT, remaining challenges, and how CDRH’s Medical Device Development Tools (MDDT) Program, which qualifies tools for use in evaluating medical devices to streamline device development and regulatory evaluation, could be a pathway to qualify the use of MAT in place of the rabbit pyrogen test and the limulus amebocyte lysate test for medical device testing. Workshop outcomes and fol­low-up activities are discussed.

Background: Within the EU, some of the challenges and perceived risks now facing medical device (MD) developers result from changes in the regulatory framework, emphasizing safety. Therefore, medical technology companies must adopt stricter quality assurance measures so that individual devices can be speedily tracked and retrieved in emergency situations.Objectives: We highlight the challenges and risks faced by the European medical devices industry, particularly those faced by SMEs in the Czech Republic. We address two important research questions: Q1. Do advantages from increased regulation outweigh the additional expenses? Q2. As many MD developers are SMEs, will the new regulatory regime result in some of those companies going out of business and therefore impede future innovation?Methods: The paper focuses on a single case study, with the situation and outcomes discussed in the context of the financial results of a further 50 medical device manufacturers marketing in the Czech Republic.Results: Our findings suggest that the new legislation will result in improved safety, facilitate product recalls, but the cost and administrative burden may be high. The evidence also indicates that some SMEs may be forced to diversify to “non-medical” products, with the inevitable loss of innovative MDs being made available to patients and healthcare providers.

Potential Benefits

This paper examines the importance of modeling and simulation in manufacturing, specifically medical device manufacturing. While the use of simulation analysis is steadily gaining acceptance in many industries, medical device manufacturers are still apprehensive of its use and value. It is seen as a non-value added approach given the widespread acceptance of other approaches like lean manufacturing, six-sigma, just-in-time manufacturing etc. Here we will explore the potential benefits of simulation in the manufacturing of medical devices and highlight how it can complement the other process improvement approaches and techniques. When a valid and credible model of a system is established it can be a very effective tool which manufacturers can use to address numerous challenges they face every day - broadly classified into Resource Allocation, Performance Evaluation and Operations Excellence. For manufacturers who are serious about remaining competitive in the 21st century, they cannot afford to ignore this powerful approach. The industry is well positioned to embrace this technology and can leverage key ingredients from existing systems. The US Food and Drug Administration (FDA) sees a lot of benefit in simulation technology and recommends its use to device manufacturers through a series of guidance documents. The relative benefit of using this approach along with other established approaches of process analyses and improvement like lean cannot be overemphasized. Towards the end of this study, a comprehensive simulation model of case in point manufacturing facility has been developed and its results demonstrate how effective this technology can be in solving real life manufacturing problems in a systematic manner, with a data driven approach.

Medical Device Regulation

In the Czech Republic, the medical device industry is an important sector with a strong tradition and has high added value and perspectives in demand under changing demographic and social structures. The aim of this article is to describe and analyze the complex issues of the new European Commission Medical Device Regulation (MDR) 2017/745 from the perspective of the strategic decisions of companies that have to comply with the requirements imposed on them by the new legislation and at the same time fulfill their own business needs and goals. The legislative changes significantly affect the standards, processes, and certifications in the medical device sector. The classification system of medical devices has been revised to more appropriately reflect the possible health risks associated with use of modern high-end technology in healthcare. The requirement is to categorize each device under the highest possible risk class, which means for the medical device manufacturers to carefully review the new rules and regulations and classify their devices accordingly.
