What material is the Dexcom filament and insertion needle made from?
The Dexcom insertion needle in all of our products is made of 304 stainless steel which includes 10% medical grade nickel. The act of inserting the sensor wire will briefly (milliseconds) expose the user to nickel.
The sensor filament design (in terms of wire and membranes) are the same for all of our products. The sensor probe consists of a Platinum and Tantalum core wire/filament. These metals are of high purity and do not contain nickel. This metal wire is coated with a polyurethane based dielectric coating, a Silver and Silver Chloride containing resin, followed by our proprietary membrane coatings. All of which have been validated for safety through biocompatibility and safety testing
