MicroPort Gets Knee Simulations Up and Running

May 15, 2013 4:20 pm | by Nick O’Donohoe, Senior Account Executive, Parker Group | Comments

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.


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 | Comments

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.

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. | Comments

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.

Weaving Flexibility and Strength into Stent Design

May 9, 2013 3:05 pm | by Kasey Panetta, Managing Editor, ECN | Comments

Though 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. | Comments

The 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 | Comments

In 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 | Comments

A 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 | Comments

Exposed 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. | Comments

A 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.  


Prototyping Personalized Medical Solutions

May 1, 2013 2:36 pm | by Scott Summit, Founder, Bespoke Innovations | Quickparts | Comments

This article offers the personal perspective of an industrial designer in his quest to utilize advanced prototyping technology to enable the fabrication of custom orthopedic prosthetics that not only offered the standard function required of such a device, but also one that reflected the personality and style of its owner.


Cut to the Bone

April 30, 2013 2:54 pm | by Gus Breiland, Customer Service Engineer Manager, Proto Labs Inc. | Proto Labs, Inc. | Comments

As material costs rise, designers are attempting to use as little as possible for their components without sacrificing the functionality or durability of a part. While this is the goal for virtually every designer across every industry, accomplishing it can be a challenging task. Using rapid injection molding for prototype parts, designers can get a much better handle on achieving this task.

Bigger, Faster, Stronger—The New Fully Integrated CMO

April 29, 2013 2:40 pm | by Jon Spaeth, Director of Product Development, and Bill Welch, Chief Technology Officer, Phillips-Medisize | Phillips-Medisize | Comments

In today’s medical device manufacturing space, OEMs are seeing partners who can handle not only the product development and prototyping of their idea, but those who have the ability to take that idea into production and manufacturing. This article looks at the value of working with a fully integrated development and manufacturing partner.

Hearing the Call for Rapid Prototyping

April 26, 2013 12:22 pm | by Avi Cohen, Manager, Dental and Medical, Objet | Comments

The manufacture of hearing aids has traditionally involved a time-consuming, manual process that limited the amount of production that could be achieved by a single technician. However, with the implementation of rapid prototyping technology alongside CAD/CAM solutions, this process has been sped up exponentially. This article looks at the changing trend for the production of hearing aids.


Portable Ventilators & the Advanced Design of Brushless DC Motors

April 25, 2013 5:07 pm | by Michael Bloom, President, Sinotech | Sinotech | Comments

The BLDC motor is a synchronous electric motor that has coils wound around the stationary lamination stack of a stator—not a rotating armature—and magnets mounted on a rotor. This basic design has allowed engineers to create BLDC motors small enough to fit into portable ventilators used in hospitals, emergency vehicles, and homes.
