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.
The fiber laser marker has become commonplace for mainstream marking applications, providing excellent high speed contrast marking of steels and plastics, as well as materials micromachining, including cutting, drilling, scribing, and ablation. Lasers with better beam quality can mark or machine faster, and provide better feature resolution and improved process quality.
This article will walk through the various characteristics of these resistors, including high resistance values, high voltage handling, small size, resiliency, and more, to demonstrate how they might aid in the design of medical devices.
When it comes to wearable robotics and exoskeletons, the engineers behind the Indego Exoskeleton are striving to be at the forefront of this emerging technology. Parker Hannifin, with the cooperation of Vanderbilt University, created an exoskeleton with one primary goal in mind—to create a useful, well designed, user friendly, empathetic product that would improve the lives of its users.
Knees can perform extraordinary tasks, but when all the activity they encounter takes too great a toll over time, total knee replacement surgery may be advisable. Product developers and manufacturers have to create total knee replacement implants that will perform as long as possible. Realistic simulation with finite element analysis software has now become vital to that process.
When it comes to molding for medical devices, effective process monitoring isn’t just about getting a part correct, but rather, it could be a matter of life or death. Ensuring product is produced within defined limits is critical. This article highlights the considerations required to be certain effective process monitoring has been established for medical molding.
Ceramic injection molded products are increasingly being used in the manufacture of innovative medical components and devices, thanks to the unique range of material and performance attributes. In this article, the material, its key features, and the growing range of applications for which it is suited are highlighted.
The advantages and benefits of external gas-assisted injection molding, how it compares to internal gas-assisted injection molding, and in-roads the process is making into medical device applications will be examined in this article. In addition, critical steps that form the basis of successful external gas application will be highlighted and real-life examples provided.
