E-Beam vs. Gamma Sterilization

May 23, 2013 2:39 pm | by Larry Nichols, COO, and Bob Starrett, CTO, NUTEK Corporation | NUTEK Corporation | Comments

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.

Replacing the Cadaver for Surgical Students

May 22, 2013 4:06 pm | by Kasey Panetta, Managing Editor, ECN | Comments

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.

MicroPort Gets Knee Simulations Up and Running

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

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.
