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 | Intellidrives, Inc. | 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).

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

Hearing the Call for Rapid Prototyping

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