Intervertebral disc treatment devices and methods
First Claim
1. An intervertebral disc treatment device for treating an intervertebral disc of a vertebrate while retaining an intact annulus fibrosis, comprising:
- a compressible fibrous body configurable to a compressed state for passage through an opening in the annulus fibrosis and into a disc cavity defined by the annulus fibrosis;
said body configurable to an expanded state to reside within the disc cavity and have a dimension greater than said opening so as to resist expulsion from said opening; and
said body incorporating an effective amount of a tissue growth factor.

Abstract
Intervertebral disc treatment devices and methods are provided. An intervertebral disc treatment device includes a fibrous body sized for introduction into a disc cavity of a damaged disc wherein the body incorporates an effective amount of a tissue growth factor. Intervertebral disc treatment apparatuses are also described that include such a disc treatment device in combination with a delivery apparatus for retaining and selectively releasing the device into the disc cavity. Methods for treatment include providing a disc treatment device as described above and inserting the device into an opening in an annulus fibrous and into the disc cavity. The methods further include stimulating tissue growth within the disc cavity of the intervertebral disc.

- 48. A method of treating an intervertebral disc, comprising introducing a fibrous body into a disc cavity of a damaged disc between adjacent vertebrae, said body incorporating an effective amount of a tissue growth composition to stimulate soft tissue formation within the disc cavity sufficient to accommodate at least a portion of compressive loads occurring between the adjacent vertebrae.
-
50. A method of treating an intervertebral disc, comprising:
-
(a) providing a fibrous body sized for introduction into an opening of an annulus fibrosus of said disc;
(b) inserting said fibrous body through said opening, said body thereby blocking effluence from said opening; and
(c) providing a tissue growth composition within the disc space of said intervertebral disc. - View Dependent Claims (51)

- 52. A method of preventing effluence from a disc cavity of a damaged intervertebral disc having an annulus Fibrosus having an opening, said method comprising inserting a fibrous plug into the cavity of said disc so as to block effluence from said opening.
-
54. A method for treating a damaged intervertebral disc, comprising:
-
(a) providing an opening in an annulus fibrosis of the damaged intervertebral disc;
(b) passing a non-prosthetic delivery body through said opening and into a disc cavity defined by the annulus fibrosis, the delivery body incorporating a tissue growth factor; and
(c) the delivery body releasing the tissue growth factor in the disc cavity and promoting tissue growth in the disc cavity.
