Abstract
An expandable intervertebral total disc replacement implant, including an inferior component, including a first core including a first outer surface and a first inner surface, and a first arm telescopingly engaged with the first core, a superior component, including a second core including a second outer surface and a second inner surface, and a second arm telescopingly engaged with the second core, and an expansion mechanism connected to the first core, the second core, and at least one of the first arm and the second arm.
Claims15
An expandable intervertebral total disc replacement implant, comprising:
- an inferior component, including:
- a first core comprising a first outer surface and a first inner surface;
- and
- a first arm telescopingly engaged with the first core;
- a superior component, including:
- a second core comprising a second outer surface and a second inner surface;
- and
- a second arm telescopingly engaged with the second core;
- and
- an expansion mechanism connected to the first core and the second core, and directly secured to at least one arm of the first arm and the second arm;
- wherein the expansion mechanism is an inflatable sac;
- wherein as the expandable intervertebral total disc replacement implant is expanded, the expansion mechanism:
- displaces the superior component in an axial direction with respect to the inferior component;
- and
- displaces the at least one arm radially outward with respect to its respective core.
An expandable intervertebral total disc replacement implant, comprising:
- an inferior component, including a first core comprising a first outer surface and a first inner surface;
- a superior component, including a second core comprising a second outer surface and a second inner surface;
- an arm telescopingly engaged with at least one of the first core and the second core;
- and
- an inflatable sac connected to the first core, the second core, and the arm, wherein at least one of the first inner surface and the second inner surface comprises a recess, and the inflatable sac is pivotably engaged with the recess;
- wherein the inflatable sac is operatively arranged to displace:
- the superior component in an axial direction with respect to the inferior component;
- and
- the arm in a radial direction with respect to its respective core.

- an inferior component, including a first core comprising a first outer surface and a first inner surface;
- a superior component, including a second core comprising a second outer surface and a second inner surface;
- an arm telescopingly engaged with at least one of the first core and the second core;
- and
- an expansion mechanism connected to the first core and the second core, and secured to the arm, wherein at least one of the inferior component and the superior component are pivotable with respect to the expansion mechanism;
- wherein to expand the expandable intervertebral total disc replacement implant, the expansion mechanism is operatively arranged to displace:
- the superior component in an axial direction with respect to the inferior component;
- and
- the arm in a radially outward direction with respect to its respective core.
