Abstract:
1. A spinal stabilization device comprising: a. at least one spring member defining a helical geometry and an end region; b. a structural member defining a threading channel for interaction with the at least one spring member, wherein the threading channel defines an aperture that is in helical alignment with a helically-shaped groove defined on an outer face of the structural member; and c. a weld cap defining a helical channel groove on an in inner face for cooperation with the helically-shaped groove on the outer face of the structural member to capture the end region of the at least one spring member between the helical groove defined on the inner face of the weld cap and the helically-shaped groove defined on the outer face of the structural member; wherein the at least one helical spring member is threaded within the threading channel of the structural member such that the end region passes through the aperture defined by the threading channel and rests in the helically-shaped groove on the outer face of the structural member; and wherein the weld cap is welded with respect to the structural member with the end region of the at least one helical spring positioned therebetween, thereby securing the end region of the at least one spring member between the weld cap and the structural member.
