Abstract

A surgical implant device may include a first substantially planar portion having a first surface area, a second substantially planar portion having a second surface area, and a coupling device for connecting the first substantially planar portion to the second substantially planar portion. The coupling device facilitates expanding and contracting the first and the second substantially planar portion in order to provide an implant surface area corresponding to the first surface area during insertion of the surgical implant within an incision, and having a third surface area corresponding to both the first surface area and at least a portion of the second surface area following insertion of the surgical implant within the incision.

Claims

1-20. -20. (canceled)

21. A surgical implant device adapted for repairing injury to the floor or walls of an orbit of an eye, comprising:

a first planar portion having a first top surface area;

a second planar portion having a second top surface area;

a swiveling mechanism that couples the first and the second planar portions for laterally swiveling the first and the second planar portions apart between an expanded state and an unexpanded state; and

an interlocking mechanism for maintaining the relative positions of the first and the second planar portions upon laterally swiveling laterally apart the first and the second planar portions to the expanded state, the interlocking mechanism including complementary interlocking structures located on the first and the second planar portions, wherein during the unexpanded state the surgical implant includes a top surface area, as observed from a plan view, corresponding to the first top surface area of the first planar portion, and wherein during the expanded state the surgical implant includes a top surface area, as observed from a plan view, corresponding to both the first top surface area of the first planar portion and at least a portion of the second top surface area of the second planar portion, the surgical implant being adapted for placement within an incision in the unexpanded state and adapted to be laterally swiveled to the expanded state following placement within the incision, wherein in the expanded state, the surgical implant is adapted to cover an injury surface area located within the incision that includes a width dimension that is larger relative to a width dimension of the incision, the implant device as a whole having a planar shape adapted for placement within the incision.

22. The implant device of claim 21, wherein during the expanded state a first end region of the coupled first and second planar portions includes a smaller width relative to a second end region of the coupled first and second planar portions opposing the first end region.

23. The implant device of claim 21, wherein the first substantially planar portion and the second substantially planar portion comprise a thickness of about 0.6-1.5 millimeters.

24. A surgical implant device adapted for repairing injury to the floor or walls of an orbit of an eye, comprising:

a first planar portion having a first top surface area;

a second planar portion having a second top surface area;

a swiveling mechanism that couples the first and the second planar portions for laterally swiveling the first and the second planar portions between an expanded state and an unexpanded state; and

an interlocking mechanism for maintaining the relative positions of the first and the second planar portions upon laterally swiveling laterally apart the first and the second planar portions to the expanded state, the interlocking mechanism including complementary interlocking structures located on the first and the second planar portions, wherein during the unexpanded state the surgical implant includes a top surface area, as observed from a plan view, corresponding to a third top surface area, and wherein during the expanded state the surgical implant includes a top surface area, as observed from a plan view, corresponding to a fourth top surface area, the third top surface area having smaller surface area relative to the fourth top surface area and a larger surface area relative to the first surface area, and the fourth top surface area having a smaller surface area relative the second surface area.

the surgical implant being adapted for placement within an incision in the unexpanded state and adapted to be laterally swiveled to the expanded state following placement within the incision, wherein in the expanded state, the surgical implant is adapted to cover an injury surface area located within the incision that includes a width dimension that is larger relative to a width dimension of the incision, the implant device as a whole having a planar shape adapted for placement within the incision.

25. The implant device of claim 24, wherein during the expanded state a first end region of the coupled first and second planar portions includes a smaller width relative to a second end region of the coupled first and second planar portions opposing the first end region.

26. The implant device of claim 24, wherein the first substantially planar portion and the second substantially planar portion comprise a thickness of about 0.6-1.5 millimeters.

27. A surgical implant device adapted for repairing injury to the floor or walls of an orbit of an eye, comprising:

a first planar portion having a first top surface area;

a second planar portion having a second top surface area;

a swiveling mechanism that couples the first and the second planar portions for laterally swiveling the first and the second planar portions apart between an expanded state and an unexpanded state; and

an interlocking mechanism for maintaining the relative positions of the first and the second planar portions upon laterally swiveling laterally apart the first and the second planar portions to the expanded state, wherein during the unexpanded state the surgical implant includes a top surface area, as observed from a plan view, corresponding to the first top surface area of the first planar portion, and wherein during the expanded state the surgical implant includes a top surface area, as observed from a plan view, corresponding to both the first top surface area of the first planar portion and at least a portion of the second top surface area of the second planar portion, the implant device as a whole having a planar shape adapted for placement within the incision.

28. The implant device of claim 27, wherein the first substantially planar portion and the second substantially planar portion comprise a thickness of about 0.6-1.5 millimeters.
