Medical Teaching And Training Models

Another area of medical illustration is the production of medical models. There are numerous varieties of medical models, from the purely visual, to those for training, to those purely for engineering. Rapid prototype models have become a common tool for planning complex surgeries. Examples of these are shown in Chapter 6. Training models mimic some features of a surgical procedure, such as the retraction of tissue for an open procedure, the trackabilty of a catheter, or the insertion force of...

Fogarty, M.D., is a legend in the medical device community. He is a retired vascular surgeon, a highly regarded winemaker,1 a venture capitalist, and a leading medical technology innovator. He has founded or co-founded more than 30 companies in the medical device or services field, holds more than 100 patents, and is author of more than 170 scientific and medical articles. Dr. Fogarty invented the Fogarty embolectomy catheter while still a medical student and also developed the stent...

The Medical Illustration Bookshelf

Medical device designers can benefit from having a complete library of good anatomical reference material. The question is What is good reference material A number of years ago, the Association of Medical Illustrators22 published a suggested reference bookshelf, and some of those recommendations are reflected in this list. There is no one atlas that covers every structure in the way and in the detail you might require. It is a good idea to go to a school of medicine bookstore and look at each...

Other Ways To Tip A Catheter

In this example, a custom-made glass mold is used to form the tip. Since many of these devices were to be built, this was the best solution. However, you may find yourself at the workbench late some afternoon or evening and need to put a tip on a catheter for an in vitro prototype. What do you do then One way to make a tipping die is to fabricate one out of brass or aluminum on a lathe. Drill out a metal rod to the diameter of the catheter tube with a plus tolerance for clearance. Grind a drill...

Arm Probe Scanners

Contact probe scanners are available from Faro (Lake Mary, FL, www. faro.com), Immersion (Microscribe) (San Jose, CA, www.microscribe.com), and Romer CimCore (Farmington Hills, MI, www.cimcore.com). Arm probe scanners are a way to digitize objects with a higher degree of user control than automated scanning methods. Arm probe scanners are popular in manufacturing environments such as automotive and aerospace. Arm probe scanners can plug directly into three-dimensional surfacing programs such as...

Dlp Envisiontec Perfactory

Digital light processing (DLP) is a photopolymer method to build parts. Envisiontec GmbH (Marl, Germany, www.envisiontec.de) markets this technology in its Perfactory system. In this process an entire image is projected onto the surface of a vat of photopolymer. The Perfactory lens system from Envisiontec is based on Texas Instruments DLP technology. In this method, a MEMS chip reflects an image off millions of mirrors through an optical engine into the surface of the resin to be cured. In this...
