A medical suspension arm assembly including a plurality of suspension arms, with each adjacent pair of the suspension arms being connected to each other by a joint and with at least one of the joints comprising an infinite rotation joint. The infinite rotation joint allows the suspension arms at the infinite rotation joint to have unlimited rotation relative to one another. Cabling including at least one fiber optic cable extends through each of the suspension arms and each joint. A wired medical unit is connected to an end of the plurality of suspension arms. High definition video, data and power can be transferred along each one of the suspension arms through the cabling and across each joint.
