Diagnostic 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.
Ingestible 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 use of lasers in the development of medical devices through to their actual usage in the devices themselves has been a steadily growing trend. The capabilities and functionality they offer to both design engineers as well as healthcare professionals is varied and beneficial. This article looks at the advantages lasers offer in the development of medical devices.
The portable medical devices industry is a fast growing world. With the advent of various smart technology and wireless capabilities, this medical field has become one of the most intriguing with the promise of great potential for future healthcare.
Most often, it seems medical device manufacturers are deciding between machining and molding for their component fabrication needs. However, there are alternatives that should be explored. Stamping offers an array of excellent advantages for designers who need micro parts made from metal materials.
Surgical 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.”
There are an array of factors that impact the design of medical devices, from available components to healthcare trends. In this Roundtable presentation, participants spoke to the way in which healthcare trends are impacting material development and, as a result, how materials are then impacting medical device design.
Ceramic 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 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.
The 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.
As 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.
The 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.
Many 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.
Surgical 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.
When 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. Fortunately, due to timely surgery and a custom-made prosthetic skull plate designed by MedCAD, Guo is able to do almost everything he could do before the fateful match.
