A spinal implant includes a coiled wave spring configured to surround a nucleus. The wave spring is formed with at least one wire having a sinusoidal shape and made of a shape memory material. The shape memory material is tailored to achieve a stress-induced martensitic transformation when a critical stress is exceeded. The implant may further include an artificial nucleus configured to simulate a disc nucleus. Methods of forming and implanting the spinal implant are also disclosed.


Apparatus for providing compression within a body, the apparatus comprising: a compression plate comprising first and second opposing regions connected together by at least one elastic bridge member, wherein the at least one elastic bridge member has a non-linear configuration when it is in its unbiased condition but is capable of being elastically deformed to a more linear configuration upon the application of force to the at least one elastic bridge member, and at least one opening formed in each of the first and second opposing regions, wherein the at least one opening in each of the first and second opposing regions is configured to receive a fastener; such that the openings in the first and second opposing regions are separated by a first distance when the at least one elastic bridge member is in its non-linear configuration, and openings in the first and second opposing regions are separated by a second distance when the at least one elastic bridge member is in its more linear configuration, and further wherein the second distance is greater than the first distance.

Apparatus for securing a first bone fragment to a second bone fragment, said apparatus comprising: a fusion device, said fusion device comprising: a shaft having a first end and a second end; a first bone-engaging feature formed on said shaft at a first location, said first bone-engaging feature comprising at least one barb which, in its unbiased condition, flares outwardly from the longitudinal axis of said shaft and which is capable of being elastically constrained to a position substantially parallel to the longitudinal axis of said shaft, such that said first end of said shaft may be advanced into a hole in the first bone fragment when said at least one barb is elastically constrained to a position substantially parallel to the longitudinal axis of said shaft but is prevented from being withdrawn from the hole in the first bone fragment when said at least one barb is in its unbiased condition; and a second bone-engaging feature formed on said shaft at a second location, said second bone-engaging feature comprising at least one barb which, in its unbiased condition, flares outwardly from the longitudinal axis of said shaft and which is capable of being elastically constrained to a position substantially parallel to the longitudinal axis of said shaft, such that said second end of said shaft may be advanced into a hole in the second bone fragment when said at least one barb is elastically constrained to a position substantially parallel to the longitudinal axis of said shaft, but is prevented from being withdrawn from the hole in the second bone fragment when said at least one barb is in its unbiased condition.
