Brushless Motors with Integral Motion Controls Benefit Medical Product Development

June 5, 2012 7:25 am | by John Morehead | Comments

Product development in medical devices is rapidly embracing the distributed motion benefits of brushless servo motors with integral motion controls for many reasons. The most important is that smart servo motors allow medical device developers to concentrate on and grow their core competencies without having to get into the minutiae of motion control, a specialized field of engineering unto itself.

Living in the Material World

June 5, 2012 7:00 am | by Gus Breiland | Comments

Molding prototype components enables the medical device designer to get a “preview” of a finished part before going into full production. However, to get the full benefit of this, material selection should be just about completed, including any additives that are to be used. This article looks at the considerations for medical device developers when planning molded prototype components.

Conformal Cooling Using DMLS

June 5, 2012 6:44 am | by Tim Ruffner | Comments

Conformal cooling in tool design is a concept that’s fundamentally sound. The trouble lies in the mechanics. Design obstacles imposed by performance boundaries in available machining processes often put its merits out of practical reach. The emergence and attainability of DMLS technology gives toolmakers the design latitude to make conformal cooling a profitable reality.

How Low Can You Go?

June 5, 2012 5:58 am | by Donnie Garcia | Comments

"Low power” is almost always used to describe MCUs, and it’s usually accompanied by power mode specifications and battery life calculations based on milliamp hours. While those aspects of low power design are important, there are other embedded design techniques that can lead to a significant extension of the usable lifetime of a product, which is the focus of this article.

Injection Molding Small Complex Bioabsorbable Implants

June 5, 2012 5:25 am | by Tanner Hargens | Comments

Injection molding intricate components for medical device implantables is a difficult task on its own. Add absorbable polymer to the equation and it becomes many times more challenging. This article reviews several of the barriers to success in this area of component fabrication for implantable medical devices.   

Designing for the User

June 5, 2012 5:04 am | by Shigeru Tanaka | Comments

There are a number of successful approaches designers can take when developing a new medical device. However, as the market transforms with outpatients being the primary users of many devices over health care professionals, the critical design issues transform as well. This article looks at designing medical devices that are to be used by the outpatients themselves.

Cardiac Catheter Leak Detection

May 30, 2012 12:58 pm | by Joe Pustka | Comments

With the variety of tasks a cardiac catheter must accomplish, testing them to ensure safety and reliability is of critical importance. However, due to the range of tests that must be completed on them, this process can be lengthy and challenging. This article highlights the difficulties that can be encountered and offers a solution in the form of a new testing system.

Balloon Tubing – The Key to Good Balloons

May 30, 2012 12:43 pm | by Apur Lathiya | Comments

As more medical device OEMs invent new ways to navigate the tortuous anatomy and open up clogged arteries, one constant remains—without high quality balloon tubing, producing high quality balloons consistently can be a real challenge. This article will highlight some of the considerations in manufacturing balloon tubing from Polyamide or Polyamide co-polymer materials.

Pinch It: Contamination-Free Fluid Management Using Pinch Valves

May 30, 2012 12:09 pm | by Don Harris | Bimba Manufacturing Company | Comments

Transferring fluids in healthcare applications can be a complicated procedure when trying to ensure there is no contamination from outside surfaces. Pinch valves offer a solution via a pinching mechanism that “pumps” the fluid through the tubing. This article examines the technology, offers considerations for selection, and highlights the types of tubing that are best suited for use.
