The present invention provides methods and devices for treating the annulus of an intervertebral disc. The methods and devices can employ an expandable treatment device which is deployed at least partially in the subannular space. Fixation devices and methods are also disclosed, which help to secure
The present invention provides methods and devices for treating the annulus of an intervertebral disc. The methods and devices can employ an expandable treatment device which is deployed at least partially in the subannular space. Fixation devices and methods are also disclosed, which help to secure the treatment device in place.
1. A method of treating an intervertebral disc comprising: providing a first delivery tool having a proximal portion and a distal portion, the distal portion carrying a treatment device having a first configuration in which the treatment device has a first length and a first width;providing at least
1. A method of treating an intervertebral disc comprising: providing a first delivery tool having a proximal portion and a distal portion, the distal portion carrying a treatment device having a first configuration in which the treatment device has a first length and a first width;providing at least one second delivery tool having a proximal portion and a distal portion, the distal portion carrying at least one affixation device configured to affix said treatment device to the intervertebral disc tissue;introducing the distal portion of the first delivery tool and the treatment device at least partially into the intervertebral disc and causing the treatment device to transition to a second configuration in which the treatment device has a second length and a second width, wherein the second length is shorter than the first length and the second width is wider than the first width;introducing the distal portion of said at least one second delivery tool at least partially into the intervertebral disc;deploying the at least one affixation device into, or through, a portion of the annulus and a portion of the treatment device so as to, at least partially, secure said treatment device to the intervertebral disc;removing said at least one second delivery tool; andremoving said first delivery tool. 2. A method of claim 1, wherein said affixation device is comprised of one of more bands, filaments, lines, wires, tethers or sutures. 3. A method of claim 1, wherein said at least one affixation device comprises at least one anchor portion and at least one band portion. 4. A method of claim 3, wherein said band portion material is comprised of a mesh tube. 5. A method of claim 1, wherein said affixation device further comprises a connecting assembly capable of being secured with a retainer, clip, locking element or knot after the process of being shortened. 6. A method of claim 1, wherein said affixation device is secured with a band locking device. 7. A method of claim 1, wherein said treatment device comprises material to facilitate regeneration of tissue. 8. A method of claim 1, wherein said affixation device comprises material to facilitate regeneration of tissue. 9. A method of claim 1, wherein said treatment device comprises a mesh, patch, scaffold, stent, barrier or membrane. 10. A method of claim 1, wherein said at least one affixation device comprises two anchor portions. 11. A method of claim 10, wherein one anchor portion is disposed, in use, at the outer surface of the annulus, and the second anchor portion is disposed, in use, within the intervertebral disc.
