Blom Singer® Increased Resistance
Clinical application
The Blom Singer® Increased Resistance prosthesis was developed from the Blom Singer® Classic Indwelling prosthesis. The silicone hinge on the valve flap was reinforced to improve the durability of the valves in patients with underpressure related valve opening. The resistance during speaking is higher than in a low-resistance prosthesis.
