Abstract:
1. A device to space vertebral members comprising: a first plate; a second plate; a deploying device positioned between the first plate and the second plate; first, second, and third link pairs each comprising a first end connected to the first plate, and a second end connected to the second plate, the first link pair connected to a first section of the deploying device at a first connection, the second link pair connected to a second section of the deploying device at a second connection, the third link pair connected to a third section of the deploying device at a third connection, and the first, second, and third connections being disposed on and spaced apart along a longitudinal axis of the device, each of the first, second, and third sections including a tubular shape and being in a telescoping arrangement with the first section positioned within the second section and the second section being positioned within the third section; the deploying device positionable between a first orientation having a first height along a transverse axis of the device between the first and second plates, a second orientation having a second height along the transverse axis between the first and second plates that is greater than the first height, and a third orientation having an angle between the plates that is greater than in the first and second orientations, a first distance between the first connection and the second connection being smaller in the second orientation than in the first orientation, and a second distance between the third connection and the second connection being smaller in the third orientation than in the second orientation; wherein the second distance differs in the second orientation compared to the third orientation with the first distance substantially constant in the second orientation compared to the third orientation; the first, second, and third sections of the deploying device being movable relative to each other to independently adjust the height and the angle of the plates.
