Making microwire components for medical devices

Often, micromanufacturers think first and foremost about machining microparts, but a simpler way for many parts is to simply bend them into the needed shape.  Companies such as the five highlighted below, bend microwire into forms, coils and springs, and can produce electrical contacts, medical catheter devices, guide wires, clips, and a host of other products in a matter of seconds on wire as fine as 0.0007”. They use virtually any material from stainless steel alloys to exotic materials, and feature a variety processing and post-processing techniques to turn minute wires into complex and multifunctional end products.

The following is a more in-depth look at the materials and technologies used by The D.R Templeman Co., Plainville, Conn., Custom Wire Technologies Inc., Port Washington, Wis., Motion Dynamics Corp., Fruitport, Mich., Shannon Microcoil, Limerick, Ireland, and Derringer-Ney, Vernon Hills, Ill.
