Typically, the silicone material is loaded with a certain percentage of BaSO4. The loading percentage will depend on the level of contrast needed for the area of the body being viewed. Another common use of Barium loading has been in clinical trials and finished devices for failure detection and assessment since a part failure may be visible. Many of the major silicone suppliers provide Barium loaded materials today in the two implantable grades of silicone. While it is most common for the unrestricted silicone materials to be loaded, some of the restricted grades are as well.

Barium loading of silicone materials is common for the following applications:

1. Catheters

2. Shunts

3. Stents

4. Toe joints

5. Markers overmolded in silicone to detect and determine placement of devices

Now it is time for some questions for discussion on Barium loading. Have you ever manufactured BaSO4 loaded silicone parts? Did you load and mix the Barium at your company or did you purchase pre-mixed Barium silicone material? What Barium loaded silicone materials did you use?

Albright Technologies can mold your Barium loaded silicone medical devices in our ISO Class 7 hard walled controlled environment room. We can also source Barium loaded silicone material for you. If you need a custom mixed material with a certain percentage of BaSO4, Albright can mix it for you.
