To effectively interface the two, adhesives are called upon to manage a host of factors at play at the skin/device interface, such as moisture and movement, and also control the environment with respect to things like microbial flora, odor, or skin hydration.
Diagnostics: A Focus on Imaging, Portability, and Regulations
June 11, 2013 3:59 pm | by Kasey Panetta, Managing Editor, ECN | CommentsDiagnostic technology covers a broad range of equipment, tests, and medical fields, and recent advancements in technique and materials means that innovations are widespread and growing rapidly. Though economic conditions are preventing huge advancements in diagnostic imaging—if hospitals can’t afford the new technology, there is no point in designing it—the medical imaging community is focusing on refinement, rather than redesign.
Coating for Consumption
June 10, 2013 2:19 pm | by Lonny Wolgemuth, Sr. Medical Market Specialist, and Juan Gudino, Medical Market Manager, Specialty Coating Systems | Specialty Coating Systems | CommentsIngestible medical devices offer a convenient, non-invasive method of delivering therapeutics, enabling diagnostic procedures, or performing imaging tasks. However, ensuring that the sensitive electronics within the device are protected is a challenge. This article will highlight a coating technology that is being used to guarantee such protection is provided.
The Symphony of Surgical Robotics
June 4, 2013 3:44 pm | by Phil Brown, VP & GM, Pro-Dex Inc. – OMS | Pro-Dex | CommentsSurgical robots are becoming more of a standard in operating rooms. As such, device designers are going to need to understand the motion control technology that makes them function. This article looks at the “sheet music” that offers the guidance to the “conductor” who is instructing the “instruments.”
The Science of Ceramics in Hip Joint Replacements
May 31, 2013 2:56 pm | by Yannick Galais, Commercial Manager, Morgan Advanced Materials | Morgan Advanced Ceramics | CommentsCeramic materials have been used for artificial joints since the 1970s, yet the need for smaller medical implants with more complicated structures has created exciting new opportunities for those manufacturing ceramic solutions for the medical market. As a result, detailed and complex ceramic components are becoming increasingly specified for a wide range of applications.
Ethylene Oxide Versus Radiation Sterilization
May 30, 2013 3:52 pm | by Wendy Wangsgard, Radiation Sterilization Study Director, and Courtney Lang, Ethylene Oxide Sterilization Study Director, Nelson Laboratories | CommentsEthylene oxide and radiation sterilization make up two of the most common forms of sterilization for medical devices. As the device is prepared for release to market, knowing which type of sterilization to use for each product can save time and money.
Considerations and Complexities of Catheter Design & Development
May 29, 2013 12:00 pm | by Sean Lynn, Engineering Manager, Teleflex Medical OEM | Teleflex Medical OEM | CommentsThe extrusion of medical tubing can be a relatively “simple” task or it can present a number of challenges; it all depends on the application, materials to be used, etc. This article will focus on single lumen tubing and take a walk through a selection of the options available to the designer from the simplest to the most complex.
Smart Body Worn Sensors and Actuators
May 28, 2013 4:11 pm | by Wayne Palmer, Systems Application Engineer, Analog Devices | Analog Devices | CommentsAs capacitive sensors integrate more with emerging technology, replacing more traditional buttons, design engineers are able to get rather creative with how they can design them into devices. This article reviews how capacitive sensing can be applied to determine the quality of the contact between a medical device’s surface and the wearer’s skin.
Wireless-Enabled Remote Patient Monitoring Solutions
May 24, 2013 2:25 pm | by Rajeev D. Rajan, Senior Director of Product Management, Qualcomm Life | Qualcomm Incorporated | CommentsThe remote patient monitoring field is a rapidly growing one given the advantages it offers for home healthcare, remote regions, and elderly care. However, with it comes a long list of considerations and critical issues for designers and engineers to keep in mind. This article offers a “bird’s eye view” of this sector and many of the factors on which to maintain focus.
E-Beam vs. Gamma Sterilization
May 23, 2013 2:39 pm | by Larry Nichols, COO, and Bob Starrett, CTO, NUTEK Corporation | NUTEK Corporation | CommentsMany of the sterilization issues concerning gamma and electron beam radiation are the same. This point is supported by the fact that both technologies are governed by the same ISO standards when applied to medical device sterilization—ISO 11137 and ISO 13409. Both technologies have been proven effective at sterilization and are accepted worldwide.
Replacing the Cadaver for Surgical Students
May 22, 2013 4:06 pm | by Kasey Panetta, Managing Editor, ECN | CommentsSurgical simulators are an ideal solution for training surgeons with minimal risk to patient health and safety. This is particularly important when surgeons train for procedures utilizing arthroscopy because it requires the surgeon to perform the surgery while looking at a camera screen instead of the patient. This necessitates extensive training to ensure the doctor is an expert in the method.
3D Digital Process Aids in Skull Prosthetic Success
May 21, 2013 4:04 pm | by Bob Cramblitt | CommentsWhen Chinese exchange student Jiahone Guo suffered a cranial injury during a club soccer match, he thought "maybe I will go to see God," according to a report on WFAA-TV in Dallas/Fort Worth, Texas.
