Abstract
An intervertebral prosthetic device is provided for implanting within an intervertebral disc space between first and second vertebral bodies. The device includes a body component and a core component, one of which is an elastic-material structure and the other of which is a composite structure, including a textile structure embedded within an elastic material. The composite structure has a higher compressive modulus of elasticity than the elastic-material structure to enhance device support when in an operable position within the intervertebral disc space. In various embodiments, a porous textile structure partially covers the body component to, for example, facilitate bony in-growth or soft tissue in-growth into the device and therefore fixation of the device when in operable position within the intervertebral disc space.
