How Silicone Swelling Improves Design and Your Bottom Line

March 6, 2012 6:27 am | by Jay Tourigny | Comments

Silicone’s inability to expand or stretch without mechanical or chemical assistance coupled with its tacky surface makes assembly with rigid parts difficult. Connecting flexible silicone tubing to barbed fittings or mating molded silicone parts with complex geometries can be frustrating, messy, and time-consuming. As the use of silicone in the medical device industry continues to grow, so does the need for innovative methods that allow design engineers to design the most effective medical devices in the most efficient way possible.

Preventing Protein Build Up on In-Vivo Devices and Biosensors

March 5, 2012 11:32 am | by John Marugg, Ph.D. | Comments

Biosensors are critical components of diagnostic devices. They are tiny, integrated circuit chips that transmit readings from within the body to an external component that displays data for physicians and patients. Biosensors have many applications including important roles in continuous glucose monitors, sensors that monitor cell health, and magnetic sensors associated with microlabels and microfluidic cartridges, just to name a few. A big obstacle facing biosensors that are implanted into the body is longevity.

America Invents Act: Start Planning Now

February 9, 2012 11:00 am | by Scott P. McBride and Guy W. Barcelona Jr. | Comments

On September 16, 2011, the America Invents Act (the “Act”) was signed into law, marking arguably the most significant modification to the U.S. patent system since 1952. Although the default effective date is September 16, 2012, medical device companies should start making adjustments to their patent strategies now to better protect their investments in the future. In this article, three main modifications are discussed: the systematic change to first-to-file system; a broadening of applicable prior art; and additional patent office proceedings to challenge patentability.

Haptic-Based Design Software Plays Vital Role in Revision Hip Implant Case

February 9, 2012 10:05 am | by Kevin Atkins | Comments

Demand for personalized implants is increasing, since younger patients and longer life spans mean that more patients are receiving their first joint replacements earlier in their lifetime. When implant materials wear out, patients may need second or even third implants, called revision implants. Thermoplastic Products Corporation (TPC) uses Sensable’s Freeform to deliver them in a novel way—restoring patients to well being, while allowing their surgeon to experience computer-based surgical planning as well.

New Uses of Adhesives in Durable Medical Diagnostic Equipment

February 9, 2012 8:46 am | by Jeremy Cooler | Comments

Design engineers for medical diagnostic equipment are acutely aware of the dramatic growth and change in the healthcare industry. Medical OEMs and contract manufacturers are looking for suppliers who can help them meet new industry and federal regulations, achieve the highest quality products, support new care approaches (including patient-controlled monitoring and treatment), and drive down manufacturing costs.

Which Way to Go: CE Mark or FDA Approval?

February 7, 2012 10:30 am | by Charlie Chi, Ph.D. | Comments

Start-ups and large device makers alike have difficulty bringing new products to market without greater predictability and transparency from the FDA. According to an online survey funded by the medical technology industry’s Institute for Health Technology Studies, most medical device companies today are seeking regulatory approval and launching their products overseas first. This article will look at whether this is a good business decision for all device manufacturers.

Solving a Catheter Seal Integrity Challenge with Autocouple Devices

February 7, 2012 9:46 am | by Joe Pustka | Comments

Finding the best connections between parts to be leak tested and leak detection equipment is an inherent challenge to leak test system designs. Flat pad surface seals have a potential to mask leakage by holding parts together with leaking seams. Autocouplers that seal catheters at the distal end are a good example of best practice sealing devices for several reasons.

Usability and Wireless Technologies for Our Health: Improving the User Experience

January 6, 2012 11:36 am | by Donald Jones | Comments

The healthcare industry is transitioning from a sick care system to a health improvement system, and mobile health (mHealth) services are an important factor. Equipped with new devices and services, consumers are taking charge of their own health by seeking solutions that allow them to track their fitness, and manage chronic disease therapy and overall wellness.

Translating Lean Principles to DfX Improvements

January 6, 2012 11:08 am | by Chris Munroe | Comments

Cost pressures abound for just about every industry, but few experience the dual pressure to reduce cost without sacrificing quality at the level found in the medical industry. A true benefit of a strong Lean manufacturing philosophy is that it reduces cost by eliminating inefficiency, and, as a byproduct, contributes to improved quality.

Addressing Flow Pulsation in Medical Device Pumps

January 6, 2012 6:39 am | by William Fleming | Dynaflo Pumps | Comments

Diaphragm-type vacuum pumps are often ideally suited for a variety of medical devices. Unfortunately, flow pulsation can offer a challenge to developers, specifically in flow measurement and control. This article will focus on some simple techniques for reliable and repeatable measurement of flow and pressure, particularly where the pumped media is air or an otherwise compressible gas.

Roundtable Q & A: Machining

An Outside Perspective: Joining Forces to Bring New Technology to Market

January 5, 2012 10:53 am | by John Havard | Comments

Medical device manufacturers that attempt to handle too many tasks in the product development process without the sufficient level of competency are simply setting themselves up for failure. It is vital for them to maintain a strong expertise in those core competencies and look outside for strategic partners who can aid them. This article examines that for the product design process.
