For patients with a chronic condition such as multiple sclerosis (MS) who self-administer injectable therapies, comfort is important. This article reports on a comparison study of needles used to administer MS therapies and calls for medical device manufacturers to develop needles with decreased penetration forces to minimise trauma, which may increase patient comfort.
Quality must be designed into medical devices, including into their raw materials and components. Operating according to the critical principles of medical device good manufacturing practices ensures that the silicone tubing incorporated into devices has the highest standards of quality and safety.
Problems with the use of conventional cytotoxicity tests to evaluate biological risk with biomaterials are leading to the development of alternative procedures based on cell function. These tests, recently discussed at a conference in China, provide an attractive option for the future.
The small size, low power consumption and attractive price of micropumps make them ideal for use in medical delivery systems. This article discusses two designs of closed-loop controlled micropumps that can be employed to meet differing levels of accuracy and portability.
As the development of complex manufacturing models and virtual companies become more prevalent in today's growing global markets, it is increasingly important to support the relationships between manufacturer and supplier. Utilising these relationships will ensure that supply chains operate more effectively and reduce costs, risks and time-to-market time frames, whilst maintaining product quality.
