Disposable vs. Durable

October 28, 2011 10:03 am | by David Fink | Comments

A question must be addressed at the start of any new medical device product development process, “Will the device or a component be disposable or be durable?” With safety being of paramount importance, cost and “green” considerations also enter into the equation. This article examines both options and the considerations that must be taken into account for each.

Increased Durability, Safety and Effectiveness of Endovascular Prosthesis to Be Main Focus Adopted by Companies

October 24, 2011 11:29 am | by Prasanna Vadhana Kannan | Comments

Endovascular surgery, a form of minimally invasive surgery, is designed to access regions of the body through the major blood vessels. The basic technique involves the introduction of a catheter percutaneously (or through the skin) into a large blood vessel either through the femoral artery or vein found near the groin. The catheter is injected with a radio-opaque dye that can be seen on an X-ray or fluoroscopy imaging device. As the dye travels through the circulation, the real-time images seen by the radiologists assist in the diagnosis of diseases. Developments of intravascular balloons, stents and coils have allowed new therapies to evolve as alternatives to the traditional open surgeries.

A Process Approach to Molding Leads to Better Results

October 24, 2011 10:29 am | by Kersten Terry and Cheryl Weckle | Comments

Partnering with a molding services provider and establishing a strong relationship is critical to success for medical device manufacturers. However, a greater degree of efficiency can be established from partnering with the molder’s resin supplier as well. This article looks at the additional benefits realized from going a step further in reaching out to all parties involved in the molding supply chain.

Two-Shot Liquid Silicone and PC—A Union of Medical Materials

October 21, 2011 11:11 am | by Eric Bishop | Comments

The Challenge: A previously identified material selected to be overmolded onto polycarbonate would not properly bond without pre-treatment. The Solution: Utilizing a liquid injection molding system product, a replacement material that did not require pre-treatment and offered the ability to perform a higher production run than originally scheduled resolved the bonding challenge.

Healthsense Uses Protomold and Firstcut for Faster Product Design

October 21, 2011 10:46 am | by Brad Cleveland | Proto Labs, Inc. | Comments

The Challenge: Identify an affordable and reliable way to develop prototype parts that can withstand the scrutiny of real world testing. The Solution: Utilizing an array of services including Protomold and Firstcut, the company was able to secure a low volume run of components that were provided in near production ready materials suitable for testing.

Prepare for Validating the Injection Molding Process

October 21, 2011 10:37 am | by Rick Puglielli | Comments

Molding for medical devices involves critical processes that must offer repeatability, assurance of accuracy, and a high degree of quality. The following article will describe the basic fundamentals of the injection molding process that one needs to understand before developing an effective protocol for validating the injection molding process.

Polycarbonate Gives Sinus Therapy Device Strength and Striking Color

The Challenge: Identify a material for use in an OTC sinus therapy device that helps to enable a successful product launch. The Solution: Use a polycarbonate plastic that is low viscosity and offers excellent flame retardance, toughness, stiffness, and heat deflection.

Acrylic Polymer Injection Molding Primer

October 20, 2011 12:45 pm | by Joseph L. Mitchell, Charles Rissel, and Mark Aubart | Comments

Medical devices are molded from acrylic polymers to meet the requirements of a broad range of applications. Many of these devices are complex and challenge the skills of the injection molder with complicated mold designs that are difficult to fill. These challenges can be overcome with the selection of the proper grade of acrylic polymer and appropriate injection molding parameters.

From Macro to Micro—Automated Microfluidic Sanger Sequencing

August 15, 2011 12:59 pm | by James Nelson | Comments

Microfluidic Sanger sequencing is a lab-on-a-chip application for DNA sequencing. Samples are typically in milliliter volumes—the ‘macro world’—and must be interfaced to a microfluidic system that handles only microliters. The process is relatively expensive when performed manually due to the expense of the Big Dye and the reagents required for the clean-up method. However, by integrating microfluidic technology with a highly reliable robotic system, reagent volumes can be drastically reduced, generating substantial cost savings.
