  • How To Ramp Up High Volume Bioabsorbable Micro Component Production While Decreasing Part Price

    Many OEMs will utilize multi-cavitation tooling to reduce piece part prices while preparing to increase the production volume of a micromolded component. While this may be a cost effective approach for simple thermoplastic parts, it may not be the best technique for micromolded parts, especially those made of bioabsorbable or high dollar value materials. This article discusses overcoming expenses such as material waste, and mold and automation issues, and presents four key areas for cost savings in bioabsorbable products.

Using A Component Management Process To Scale Up Manufacturing Of Drug Delivery Devices

The best practice for fitting multiple parts into a single assembly at tight tolerances is to choose a single component supplier with a sufficient array of core competencies in advanced device manufacturing methods. The chosen supplier should also utilize a well-designed component management process that includes close attention to important elements, proper planning, and high performance levels to provide an affordable, highly scalable drug delivery device.

IoT-Enabled Medical Devices Are The Wave Of The Future

Winning in the medical devices market of the future requires mastering advanced technologies – or finding a partner with these capabilities. The global Internet of Things (IoT) in healthcare market is forecasted to reach $410 billion by 2022. To succeed in this arena, device companies need to stay out in front of manufacturing innovations so they can quickly integrate information technology (IT) functionality into their products, accelerate time to market and control costs.

Assuring Component Reliability In Medical Electronic Devices

Rapid technology advances in medical microelectronics, driven by increased service life, miniaturization, lack of redundancy and functional integration, requires a rigorous development, manufacturing and monitoring methodology to assure reliability. Such an approach must be relevant throughout the product lifecycle and, for every component in a system hierarchy. It must also be effective and efficient. This article discusses a smart end-to-end solution for capacitor reliability that can yield better, more dependable medical electronic devices.

Mind Over Machine

As a part of a fast-track effort to bring the exoskeleton from science fiction to real-world use, Proto Labs will provide custom-machined aluminum-joint housings for a futuristic brain-machine robotics system that would help paraplegics walk again. The plan is to have a working model ready for a user by the time of the powered exoskeleton race at Cybathlon, an international competition in Zurich in October.

Medical device design and development is the cyclical process of creating a device for a specific task or set of tasks, and then continuously reevaluating its effectiveness and improving upon it until the device reaches obsolescence. Design and development begins with ideation and the creation of a concept that, if found to be both fiscally and clinically viable, is then designed, engineered, and prototyped. This preclinical period includes bench testing — accomplished through simulated use of the product — and animal testing, along with any necessary redesign work.

Throughout the process, the proposed medical device, and the process by which it will be manufactured, is examined for flaws that may negatively impact the device’s safety, market viability, regulatory acceptance, customer satisfaction, usability, or profitability. Any shortcomings are corrected, and the improvements applied to the final design. Due to the wireless connectivity capabilities of many modern medical devices, cybersecurity and interoperability also must be incorporated into the design. Clinical testing is conducted, using human subjects, to further expose flaws and confirm product strengths. Once both the product design and the manufacturing process have been validated and approved by the U.S. Food and Drug Administration (FDA), production and commercialization of a device may begin.
