Intervertebral implants and methods of use

An intervertebral device positioned between vertebral members, the device comprising:

• an elastic member;
• a first endplate positioned above the elastic member and a second endplate positioned below the elastic member;
• and
• an intermediate member positioned at ends of the first and second endplates and connecting together the first and second endplates, the intermediate member and the elastic member being configured to maintain the first and second endplates in a spaced apart configuration.

An intervertebral device positioned between vertebral members, the device comprising:

• an elastic member;
• a first endplate positioned above the elastic member and a second endplate positioned below the elastic member;
• and
• an intermediate member integral with the first and second endplates and positioned at ends of the first and second endplates, the intermediate member and the elastic member being deformable to apply a force to the first and second endplates during movement of the vertebral members.

A method of stabilizing vertebral members comprising the steps of:

• inserting an implant within an intervertebral space between first and second vertebral members;
• contacting a first endplate against the first vertebral member and contacting a second endplate against the second vertebral member;
• positioning an intermediate section that connects the first and second endplates in a posterior direction;
• and
• positioning an elastic member between the first and second endplates and anteriorly to the intermediate section, the intermediate section and the elastic member being constructed of an elastic material that maintains the first and second endplates in a spaced apart orientation during movement of the first and second vertebral members.
