  • Valve mounting assembly for voice prosthesis-cartridge and ring
    Patent number: 6948526
    Abstract: The valve mounting system of the invention incorporates a hard cartridge with a grove on its outer, distal surface and a slot communicating distal from the end of the cartridge with the grove and a specially configured elastomeric valve attached to an outer band with a short tab. The band is positioned with the tab aligned with the slot and is stretched and is slid proximally over the cartridge until the tap enters the slot and the band snaps into the seats in the groove. The width of the slot is the same as the width of the tab providing exact alignment of the valve element with the seat provided in the cartridge. The tab can be disposed at an angle to the seat to preload the valve element against the seat.
