David C. Eyvazzadeh has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20190328405
    Abstract: Certain embodiments of the invention relate to a surgical procedure resulting in the fusion of transverse processes. The disclosure herein presents novel approaches for accessing transverse processes of the spine, novel methods for the delivery of fusion material for the fusion of said transverse processes, and novel tools to facilitate the procedure. Certain embodiments of the invention include a graft delivery assembly, which has a delivery shaft, delivery sheath, and at least one curved rod. Bony material is position with a graft delivery assembly, in which retraction of the delivery shaft or sheath places the bone fusion material to the fusion site. The graft delivery assembly further includes features to decorticate and prepare the bone surface for fusion.

  • Publication number: 20190117273
    Abstract: The present disclosure presents novel methods, procedures associated steps, and apparatuses to accomplish SI joint fusion in a minimally invasive manner. The preferred embodiment of the invention incorporates improved methods, procedures and apparatuses to facilitate a SI joint fusion providing a generally safer, more minimally invasive SI joint stabilization. In the method associated with the preferred embodiment of the invention, in one aspect, a path or a plurality of paths through an ilium to the sacrum is established, wherein a stabilizer device allows the securement of the sacrum to the ilium. In another aspect, a path or a plurality of paths to the SI joint is established, where bone fusion material allows fusion of the articular surface of the ilium and the articular surface of the sacrum of an SI joint.

  • Publication number: 20120177941
    Abstract: Multilayer armor includes an outside armor layer, a first armor layer underneath the outside armor layer, a second armor layer underneath the first armor layer, and a truss layer underneath the second armor layer. In another variation, the multilayer armor includes an outside armor layer, a composite layer underneath the outside armor layer that comprises a plurality of spheres, a second armor layer underneath the composite layer to provide a rigid support to the composite layer, and a third armor layer underneath the second armor layer. The second layer may comprise a composite material that includes a plurality of tightly nested layers in a self-assembling arrangement of spheres made of a high hardness material bonded together using a matrix.
