Publication number: 20230218409Abstract: A nuclear disc implant includes an inner fillable enclosure and an outer fillable enclosure. After insertion into a enucleated disc cavity, the inner enclosure is filled with a fluid and the outer fillable enclosure is filled with a curable material. The curable material is allowed to cure and the fluid is removed from the inner enclosure to leave an inner enclosure surrounded by an cured outer enclosure. A reinforcing band may be provided around the nuclear disc implant. An inflation tool to fill the nuclear disc implant is provided.Type: ApplicationFiled: February 13, 2023Publication date: July 13, 2023Applicant: SPINAL STABILIZATION TECHNOLOGIES LLCInventors: James D.

Patent number: 11638649Abstract: A multi-chamber balloon for a nuclear implant has an elastomeric membrane defining inner and outer chambers integral with a valve body. The valve body includes a core portion and sealing membrane for sealing the inner and outer chambers. An assembly for manufacturing the multi-chamber balloon includes a balloon mandrel which may be dip coated in a silicone dispersion to create an elastomeric membrane for the inner and outer chambers integral with the valve body. The elastomeric membrane formed on the mandrel is partially inverted to form a coaxial elastomeric structure with the smaller inner chamber disposed within the larger outer chamber. The valve is incorporated into the inner and outer chambers to form a unitary structure.Type: GrantFiled: April 26, 2019Date of Patent: May 2, 2023Assignee: SPINAL STABILIZATION TECHNOLOGIES LLCInventors: Nadi S.

Patent number: 11633287Abstract: A prosthesis for implantation in a de-nucleated intervertebral disc includes a fiber ring-like layer which encloses a polymeric layer to create an annular space. The annular space is inflatable with an in-situ curable liquid polymer and forms an interior cavity. The annular space may be expanded uniformly or differentially to be tailored to the needs of a particular vertebral segment and to achieve optimal disc space width and angle, thereby stabilizing the segment while preserving normal motion of the vertebral segment. The interior cavity provides a void that allows inward deformation of the implant during weight bearing activities and bending. The prosthesis can be elastically deformed through axial elongation to a reduced profile to load into a delivery cannula using pulling techniques.Type: GrantFiled: September 28, 2020Date of Patent: April 25, 2023Assignee: SPINAL STABILIZATION TECHNOLOGIES LLCInventors: Nadi S.

Patent number: 10524923Abstract: An expandable implant for augmenting a damaged or otherwise torn posterior annulus fibrosus. The implant is deployable into an evacuated posterior disc space following a subtotal nuclectomy. The implant includes an inflatable balloon which is fixed to the annulus fibrosus to protect against migration. When inflated with a curable polymer, the posterior wall of the implant is intimately disposed along the inner surface of the annulus fibrosus to provide a substantially fluid-tight seal of the annular tear or defect and reinforce the weakened posterior annulus. The anterior wall of the implant sequesters the nuclear remnant to guard against disc remnant herniation. The implant can restore intradiscal pressure and disc height. An integrated posterior reinforcement band creates a strong, yet flexible and resilient structure, resistant to penetration of the implant through the annular tear or defect.Type: GrantFiled: November 3, 2016Date of Patent: January 7, 2020Assignee: SPINAL STABILIZATION TECHNOLOGIES LLCInventors: Nadi S.

Patent number: 9295479Abstract: An exemplary nucleus removal device may be used to remove a portion of nucleus pulposus from an intervertebral disc. A nucleus removal device may include a cannula, an access tool, a maceration tool, and an evacuation tool. The access cannula is inserted into an intervertebral body laterally, creating a fissure in the annular fibrosis. The access tool 304 is slid through the access cannula and the fissure in annular fibrosis, such that a portion of access tool extends into the nucleus pulposus. The maceration tool is extended from the access tool into the nucleus pulposus, in a direction orthogonal to the axial extension of access tool, and macerates the nucleus pulposus. To assist in maceration, a stream of liquid may also be introduced into the vertebral body through the access tool before, during, or after maceration. Macerated material and liquid is removed from the intervertebral disc by the evacuation tool.Type: GrantFiled: March 14, 2013Date of Patent: March 29, 2016Assignee: SPINAL STABILIZATION TECHNOLOGIES, LLCInventors: Nadi Salah Hibri, James Douglas Lutz
