As devices continue to move out of hospitals/doctors' offices, what new technologies will further this movement? What are the healthcare implications of this trend?
We’ve cured cancer. Well...not quite, but according to some, early detection will eradicate deadly diseases. This was one of many fascinating topics covered at the 2011 Imec Tech Forum.

Increased Durability, Safety and Effectiveness of Endovascular Prosthesis to Be Main Focus Adopted by CompaniesOctober 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.
Medical device manufacturers are constantly looking for ways to eliminate waste, cut costs, save time, and generally, get products to market faster. When it comes to molding, one machine is helping to accomplish all of that. This article looks at a two-shot molding machine that can deliver consistency and repeatability while offering the additional benefits mentioned below.
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.
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.
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.
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.
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.
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.
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.
As the marketplace and economy continue to evolve, many engineering companies have turned to outsourcing for cost efficiency. Larry Goch, President of Redpoint Engineering, a mechanical engineering and design firm focusing on product design for its clients on an outsource basis, discusses the benefits of outsourcing.
Specialized Tubing and Machined Components for Medical Devices: Prototyping and Design Expertise Improves ManufacturabilityAugust 15, 2011 10:37 am | by Alicia Puputti | Comments
As minimally invasive surgery (MIS) is performed more often, the highly engineered medical devices used in MIS are in greater demand. Metal tubing, in particular, has become a significant element of new MIS devices. For instance, the MIS procedure typically starts with a metal tube piercing the abdominal wall. It is through these ports that all subsequent devices pass. Designing for manufacturability (DFM) provides economical, quick-to-market product delivery to customers, and is a key to success for tube fabricators.
