Long-Travel Piezomotors: New Innovations, New Solutions
March 22, 2012 10:43 am | by Scott Jordan and Stefan Vorndran | Articles | CommentsPiezoelectric actuation is the foundation for a myriad of mission-critical high-technology applications, from semiconductor manufacturing to genomic sequencing and medical devices. Known for nanometer precisions, piezoelectric principles are proving highly adaptable to new configurations and modalities. Recently-developed mechanisms built on a variety of novel applications of piezoelectric technology have burst through the former travel limitations familiar from classical nanopositioning mechanisms. But like those time-tested mechanisms, those built on these newer principles offer high axial force, exceptional speeds, compactness, fieldlessness, and stable position-hold without dither. These long-travel piezomotors offer valuable, proven solutions for engineers grappling with tough technical and economic needs.

Solving a Catheter Seal Integrity Challenge with Autocouple Devices
February 7, 2012 9:46 am | by Joe Pustka | Articles | CommentsFinding 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.

October 24, 2011 11:29 am | by Prasanna Vadhana Kannan | Articles | CommentsEndovascular 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.
