Devices for intervertebral augmentation and methods of controlling their delivery
First Claim
1. An intervertebral implant comprising:
- a hybrid implant structure including (i) a tissue regeneration structure for promoting tissue ingrowth comprising at least one small intestine submucosa layer; and
(ii) a shaping structure for biasing the implant toward a predetermined, at-rest configuration comprising an elastic material, the tissue regeneration structure and the shaping structure coupled together to form a reversibly extendable structure having an elongate shape upon the application of a force along an elongate direction of the elongate shape.

Abstract
Devices and methods for treating diseased or damaged portions of an intervertebral region are provided. In particular, intervertebral implants that can include use of a tissue regeneration structure having small intestine submucosa are described. The intervertebral implants can be utilized with any combination of load bearing structures for supporting loading on the implant, shaping structures for biasing the configuration of the implant, collapsible support structures for shaping the implant, and other features. Implants can also be formed with an enclosure to contain a filling material, such as an injectable small intestine submucosa formulation. Methods of delivering and utilizing the various implants are also discussed.

9. An intervertebral implant comprising:
-
a tissue regeneration structure for promoting tissue ingrowth comprising at least one small intestine submucosa layer, the tissue regeneration structure having a surface; and
a shaping structure for biasing the implant toward a predetermined configuration comprising an elastic material, the shaping structure having a surface, the surfaces of the tissue regeneration structure and shaping structure coupled and adapted to form a reversibly deformable enclosure having at least one opening. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of delivering an intervertebral prosthesis to an implantation site, comprising:
-
providing a hybrid implant biased toward a raveled, at-rest configuration, and comprising small intestine submucosa and an elastic material;
deforming the hybrid implant to an elongate shape effective to be disposed in an elongate, hollow delivery device;
delivering the hybrid implant to a desired implantation site through the delivery device; and
depositing at least a portion of the hybrid implant at the implantation site such that the hybrid implant self-ravels toward the raveled, at-rest, configuration upon removal from the delivery device. - View Dependent Claims (16, 17)

18. A method of delivering an intervertebral prosthesis to an implantation site, comprising:
-
providing a hybrid enclosure having at least one opening and biased toward an expanded, at-rest configuration, the hybrid enclosure comprising small intestine submucosa and an elastic material;
deforming the hybrid enclosure to a collapsed shape effective to be disposed in an elongate, hollow delivery device;
delivering the hybrid enclosure to a desired implantation site through the deliver device; and
depositing the hybrid enclosure at the implantation site such that the hybrid enclosure self-expands toward the expanded, at-rest, configuration upon removal from the delivery device. - View Dependent Claims (19, 20)
