The present invention relates generally to devices and methods for delivering medical devices, such as implants, to desired tissue sites, such as the intervertebral disc. In one aspect, an intervertebral disc repair and diagnostic device that is minimally invasive and that provides precise access to the desired site is provided. In some aspects, the device and method are adapted to deliver, position and expand implants that are initially oriented and compressed for minimally invasive, yet precise and effective implantation.

What is claimed is: 1. A device for delivering and positioning an implant within an intervertebral disc comprising: a cannula having a proximal end and a distal end, wherein said distal end comprises one or more expanders operable to actively expand an implant positioned beyond the innermost lamell
What is claimed is: 1. A device for delivering and positioning an implant within an intervertebral disc comprising: a cannula having a proximal end and a distal end, wherein said distal end comprises one or more expanders operable to actively expand an implant positioned beyond the innermost lamella of a disc anulus; wherein the implant comprises a device selected from the group consisting of one or more of the following: a barrier, mesh, or patch; and an advancer having a proximal end and a distal end, wherein said advancer is at least partially slideably housed within said cannula for advancing said implant out of said cannula wherein the distal end of said advancer comprises a coupling mechanism, wherein at least a portion of said coupling mechanism is coupled to the advancer and wherein at least a portion of said coupling mechanism is coupled to the implant, wherein the implant is provided in a folded configuration; wherein the implant expands to a first partially expanded configuration upon extrusion through the cannula, wherein said implant remains in its first partially expanded configuration until it is forced open to a second frilly expanded configuration; and wherein said one or more expanders applies an active force on the implant to cause said implant to unfold from its first partially expanded configuration into said second fully expanded configuration. 2. The device of claim 1, further comprising an adjustable depth stop for limiting or guiding the travel within the intervertebral disc. 3. The device of claim 2, wherein the depth stop is rotatably coupled to the cannula thereby allowing it to rotate while the depth of the cannula is maintained. 4. The device of claim 1, wherein said coupling mechanism is selected from the group consisting of one or more of the following: snaps, locks, lynch pins or the like, levers and slots. 5. The device of claim 1, wherein said device comprises an actuator for advancing or retracting the advancer. 6. The device of claim 5, wherein said actuator is selected from the group consisting of one or more of the following: triggers, slider switches, rotatable knobs or other actuators to advance and retract the advancer. 7. The device of claim 1, wherein said cannula is constructed of a material selected from the group consisting of one or more of the following: stainless steel, polyethylene, PTFE, PEEK, and PEBAX. 8. The device of claim 1, wherein said device has a length in the range of between about 10 centimeters to about 30 centimeters. 9. The device of claim 1, wherein said cannula has an outside diameter of less than about 5 mm. 10. The device of claim 1, wherein said cannula comprises a cannula handle for positioning and controlling the cannula. 11. The device of claim 1, wherein said cannula comprises a calibrated measuring surface to display depth correlations. 12. The device of claim 1, wherein said mesh is at least partially constructed of nitinol, steel, or a polymer. 13. The device of claim 1, wherein said implant comprises a seeded or unseeded tissue scaffold. 14. The device of claim 1, wherein the device for delivering and positioning an implant is adapted to deliver the implant through an opening in the disc. 15. The device of claim 14, wherein the implant comprises at least one dimension that is larger than the opening. 16. The device of claim 1, further comprising an anchor configured to fix the implant to the intervertebral disc.
