Abstract
An adjustment assembly for an adjustable prosthetic valve device includes a gearbox housing formed from two gearbox shells coupled to one another and held together by two gearbox sleeves each having an internal cavity adapted to accommodate respective lateral portions of the gearbox shells when the gearbox shells are coupled to one another. A gear assembly, including a center gear and two driven gears, is supported within the gearbox housing. Gear teeth of each of the driven gears engage gear teeth of the center gear such that rotation of the center gear causes rotation of the driven gears. At least one of the driven gears is adapted to engage a transmission mechanism that transmits the rotation thereof to another part of the adjustable prosthetic valve device to accomplish an adjustment to the size and/or shape of the adjustable prosthetic valve device.
