MicroPort Gets Knee Simulations Up and Running
May 15, 2013 4:20 pm | by Nick O’Donohoe, Senior Account Executive, Parker Group | Dassault Systemes | CommentsKnees 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.
Achieving Effective Process Monitoring Through Detailed Process Development
May 14, 2013 11:57 am | by Robert P. Gattshall, Technical Shared Services Manager, The Tech Group | The Tech Group, Inc. | CommentsWhen 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.

In this article, the material, its key features, and the growing range of applications for which it is suited are highlighted.
External Gas: The ‘Next Generation’ Gas–Assist Technique
May 10, 2013 4:17 pm | by Michael Hansen, Ph.D., Senior Technical Development Engineer, MackMedical/Mack Molding Co. | Mackmedical/Mack Molding | CommentsThe 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.
Weaving Flexibility and Strength into Stent Design
May 9, 2013 3:05 pm | by Kasey Panetta, Managing Editor, ECN | CommentsThough traditional laser-cut stents made from nitinol are effective, the design trades flexibility for strength, which means the stents are at risk for fracture, crushing, and kinking. This is a particular issue when the stents are used with patients suffering from femoropopliteal or proximal popliteal artery disease.
mHealth Technology: Design and Development of Mobile Integrated Therapies
May 8, 2013 3:00 pm | by Paul Upham, Director of Product Marketing, WellDoc, Inc. | CommentsThe primary care practitioner is well poised to be the central point-of-care, aiding a more holistic approach to the patient. However, the patient demand curve will quickly outstrip the supply of practitioners in even the best treatment models. An enhanced approach is necessary, one that enables patient self-management combined with efficiency tools for HCPs.
Large Aperture Rotary Tables in Medical Research Tomography Applications
May 7, 2013 2:33 pm | by Greg Kane, Manager, IntelLiDrives | Intellidrives, Inc. | CommentsIn the study of human diseases and potential treatments, small animal models play a crucial role in bridging the gap between in vitro and in vivo studies. When considering imaging techniques for small animal studies, positron emission tomography (PET) is well suited to the measurement of highly specific molecular interactions (e.g., glucose uptake and target-receptor binding).
Molding Animal Free: A Case Study
May 6, 2013 3:46 pm | by Ryan Fuhr, Senior Manufacturing Engineer, and John Haley, VP of Operations, Advanced Molding Technologies | Advanced Molding Technology | CommentsA company required molded components that would come in contact with pharmaceutical processes and needed to minimize the risk of contamination, so it selected animal derived component free resins that were molded in a newly created cleanroom.
If the Climbing Shoe Doesn’t Fit, Design a New Foot
May 3, 2013 2:32 pm | by Chris Hardee, a Science and Technology Writer | CommentsExposed on a vertical face, rock climbers rely on their instincts, experience, and equipment. For C.J. Howard, a climbing enthusiast, as with all climbers, the shoes are important. But as a lower-leg amputee, even more important is the customized prosthetic foot that he designed with climbing partner and environmental/aerospace engineer Mandy Ott.
Make Two Models and Call Me in the Morning
May 2, 2013 2:47 pm | by Joe Hiemenz, Technical Communications Manager, Stratasys Inc. | Stratasys Inc. | CommentsA prototype lab is tasked with inventing solutions to design challenges presented to them by surgeons with medical device ideas. Utilizing a fused-deposition modeling machine and design software, engineers are able to create physical prototypes of medical devices that are able to be put through functional testing.
