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. A surgical implant device comprising:

a first substantially planar portion having a first surface area;

a second substantially planar portion having a second surface area;

a coupling device for connecting the first substantially planar portion to the second substantially planar portion,

wherein the coupling device facilitates expanding and contracting the first and the second substantially planar portion 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.

2. The implant device of claim 1, wherein the coupling device comprises:

a swiveling mechanism that rotatably couples the first and the second substantially planar portion; and

an interlocking mechanism that maintains the first and the second substantially planar portion in position upon the expanding of the first and the second substantially planar portion.

3. The implant device of claim 2, wherein the interlocking mechanism comprises:

a first plurality of fins associated with the first substantially planar portion; and

a second plurality of fins associated with the second substantially planar portion, wherein the first and the second plurality of fins are interlocking.

4. The implant device of claim 3, wherein the first and the second plurality of fins comprise a flexible polyethylene material that enable the first and the second plurality of fins that are interlocking to forcibly move in a discrete manner with respect to each other.

5. The implant device of claim 1, wherein the coupling device comprises:

a mating receptacle located on a vertical edge of the first substantially planar portion; and

a mating connector located on a vertical edge of the second substantially planar portion, wherein the mating connector snapably interlocks with the mating receptacle along both the vertical edge of the first and the second substantially planar portion.

6. The implant device of claim 1, wherein the coupling device comprises:

at least one snap fit receptacle located on the surface of the first substantially planar portion; and

at least one snap fit connector located on the surface of the second substantially planar portion, wherein the at least one snap fit receptacle and the at least one snap fit connector are connectively coupled.

7. The implant device of claim 1, wherein the first substantially planar portion and the second substantially planar portion comprise a thickness of about 0.6-1.5 millimeters.

8. The implant device of claim 1, wherein the first substantially planar portion and the second substantially planar portion comprise an embedded titanium mesh.

9. A method of implanting a surgical implant device having an expandable surface area, comprising:

making an incision of a first width for implanting the surgical implant device;

adjusting the expandable surface area of the surgical implant device to a reduced surface area such that the reduced surface area causes the surgical implant to have a second width that is less than or substantially the same as the first width;

placement of the surgical implant device having the reduced surface area into the incision; and

adjusting the expandable surface area of the surgical implant device to an increased surface area following the placement of the surgical implant device such that the reduced surface area causes the surgical implant to have a third width greater than the second width.

10. The method of claim 9, wherein the surgical implant device comprises an orbital implant device for placement on the orbital floor of an eye socket.

11. The method of claim 10, wherein the orbital implant device covers a fracture within the orbital floor.

12. The method of claim 11, wherein the incision is made in an orbital periosteum of the orbital floor of the eye socket.

13. The method of claim 11, wherein the orbital implant comprises a porous surface for contact with the fracture within the orbital floor and a smooth surface for contact with a region of the orbital periosteum.

14. The method of claim 11, wherein adjusting the expandable surface area comprises:

providing a first substantially planar surface corresponding to the surgical implant device, wherein the first substantially planar surface includes a first surface area;

providing a second substantially planar surface corresponding to the surgical implant device, wherein the second substantially planar surface includes a second surface area; and

moving the first substantially planar surface relative to the second substantially planar surface.

15. The method of claim 14, wherein the moving of the first substantially planar surface relative to the second substantially planar surface comprises:

generating a complete overlap between the first substantially planar surface and the second substantially planar surface for creating the reduced surface area.

16. The method of claim 15, wherein the moving of the first substantially planar surface relative to the second substantially planar surface comprises:

generating a partial overlap between the first substantially planar surface and the second substantially planar surface for creating the increased surface area.

17. A method of implanting a surgical implant device, comprising:

making an incision of a first width for implanting the surgical implant device;

placing a first substantially planar component associated with the surgical implant device into the incision, wherein the first substantially planar component includes a second width that is less than or substantially the same as the first width;

placing a second substantially planar component associated with the surgical implant device into the incision, wherein the second substantially planar component includes a third width that is less than or substantially the same as the first width; and

coupling the first substantially planar component to the second substantially planar component, the first substantially planar component including a first surface area and the second substantially planar component including a second surface area, wherein the coupling provides a surface area corresponding to the sum of the first and the second surface area.

18. The method of claim 17, wherein the coupling comprises snap fitting the first substantially planar component to the second substantially planar component within the incision.

19. The method of claim 18, further comprising:

placing at least one third substantially planar component associated with the surgical implant device into the incision, wherein the third substantially planar component includes a third width that is less than or substantially the same as the first width; and

coupling the at least one third substantially planar component to the second substantially planar component, the third substantially planar component including a third surface area, wherein the coupling provides a surface area corresponding to the sum of at least the first, the second, and the third surface area.

20. The method of claim 19, wherein the surgical implant device comprises an orbital implant device for placement on the orbital floor of an eye socket.
