Blom-Singer® Advantage
Clinical application
The valve of the Blom-Singer® Advantage prosthesis is made of silver oxide silicone. Rather than being applied as a coating, the silver oxide is incorporated in the silicone (7%), and is intended to reduce biofilm formation on the valve. There are two versions of the Blom-Singer® Advantage prosthesis. The "Hard Valve Assembly" has a reinforcing titanium ring in the shaft and is available in 20 Fr. The "Soft Valve Assembly" Blom-Singer® Advantage prosthesis does not have the titanium ring and is available in shaft diameters of 16 Fr and 20 Fr.
CAVE: The studies mentioned here apply to the "Hard Valve Assembly" Blom-Singer® Advantage prosthesis.
