The present invention is directed to a device that can be placed between two adjacent vertebrae, and that is used to repair an injury or defect in the anulus of the intervertebral disk. The implant is characterized by having a flexible structure anchored to the vertebral bone, the flexible structure connected with a patch held in place over the injury or defect. The flexible structure has a hollow interior space which can sustain inside it a hydrogel cushion. The hydrogel cushion acts as a shock absorber for the spine, maintains height of the intervertebral disk space, and prevents further disk herniation due to the narrowing of the intervertebral disk space.

A method and apparatus are described for creating a fluid seal in a subterranean well structure having a fluid seal defect. The method comprises introducing a meltable repair material proximate a structure in a subterranean well which has a fluid seal defect or enhanced seal capacity is required or it is desired to temporarily or permanently hydraulically isolate a portion the well or strengthen the structural integrity of well tubulars or tubular hangers. Exothermic reactant materials are located proximate the meltable repair material. The exothermic reactant material is ignited or an exothermic reaction otherwise initiated which supplies heat to and melts the meltable repair material into a molten mass. The molten mass flows and solidifies across the structure and the fluid seal defect to effect a fluid seal in the subterranean well structure or the structural integrity is enhanced. Examples of preferred exothermic reactant materials include thermite, thermate, fusible chemical reactants such as ammonium chloride and sodium nitrate, and oxidizers and accompanying hydrocarbon based fuels. Examples of preferred meltable repair materials include solder or brazing materials and eutectic metals which expand upon cooling and solidifying from a molten state.

A minimally invasive spinal disc defect repair method is disclosed. The method relates to insertion of disc defect repair materials that are substantially two-dimensionally shaped and which allow for insertion and preferably self retention within the disc defect with plugging of the annulus fibrosis.

Multilayer structures including a porous layer and a non-porous layer having a reinforcement member are useful as dural repair materials.

Systems, devices and methods are provided for augmenting intervertebral discs. The systems include implantable annulus repair and augmentation devices as well as implantable prosthetic materials for replacing a portion of or augmenting the annulus and/or the nucleus pulposus. The systems further include instruments for implanting the subject devices and materials in a minimally invasive manner. The methods are directed to the minimally invasive implantation of one or more of the subject annulus repair devices and the prosthetic materials concurrently.

A composition and a method of use as a dental restorative. A series of highly alkoxylated tri-functional monomers are used as a low viscosity monomer in a photo- or self-curable dental composition that resulted in low polymerization shrinkage. The mechanical strength of the restorative material was not compromised. The restorative composition may be used as a dental filling material, a cement, a liner/base, or an adhesive.

A fast line maintenance repair process for damaged composite structures includes the application of a pre-cured patch that uses a quick curing paste adhesive to bond the patch to the structure. The adhesive is cured at relatively low elevated temperatures provided by a chemical heat pack. The low temperature cure eliminates the need to dry out the part and permits the application of the repair in a hazardous environment. In a typical commercial airline application, airline maintenance personnel can install the repair at the flight gate. The repair is intended to restore the structure to a desired load capability in approximately one hour. The repair can be removed if need be with less overall damage than would occur upon removal of typical mechanically fastened repairs. All or some of the repair materials and tools can be provided in a portable kit.
