An expandable support device for use against a first bone and a second bone, the expandable support device having at least a radially expanded configuration and a radially contracted configuration, the expandable support device comprising:
- a first strut;
- a first tissue seat extending from the first strut, the first tissue seat configured to engage the first bone;
- a second strut,
- a second tissue seat extending from the second strut, the second strut configured to engage the second bone;
- wherein the first tissue seat is on a substantially opposite side of the expandable support device from the second tissue seat;
- wherein the expandable support device is configured to radially expand when the expandable support device is longitudinally compressed.
A method for supporting a first spinous process with respect to a second spinous process comprising:
- inserting an expandable support device between the first spinous process and the second spinous process, wherein the expandable support device has a first tissue seat and a second tissue seat;
- longitudinally contracting and radially expanding the expandable support device;
- seating the first spinous process in the first tissue seat;
- and
- seating the second spinous process in the second tissue seat.
