Three inventors are listed: Nicolas Roche, Nicolas Bidegaimberry, and David Rigotto.
What changed
USPTO published patent application US20260096909A1 for an instrument used to implant intervertebral disc disc prostheses. The invention covers systems and methods including the prosthesis, a cartridge, and an instrument where the cartridge receives and engages with the prosthesis prior to implantation. The instrument receives the assembly and actuation of a release driver causes expansion of release tabs to disengage the cartridge from the prosthesis.
Medical device manufacturers in the spinal implant space should monitor this application as it may represent competitive prior art for similar implantation instrument designs. Healthcare providers performing disc replacement surgeries may benefit from awareness of emerging instrumentation technologies.

INSTRUMENT FOR SYSTEMS AND METHODS TO IMPLANT AN INTERVERTEBRAL DISC PROSTHESIS
Application US20260096909A1 Kind: A1 Apr 09, 2026
Inventors
Nicolas Roche, Nicolas Bidegaimberry, David Rigotto
Abstract
Systems and methods for implantation of an intervertebral disc prosthesis include the prosthesis, a cartridge, and an instrument. Prior to implantation of the prosthesis, the cartridge receives and engages with the prosthesis to form an assembly. In addition, the instrument receives the assembly within an opening in an outer housing and engages the cartridge with a coupler of a locking shaft. Following implantation of the cartridge, actuation of a release driver causes an expansion bit of the release driver to engage release tabs on the cartridge to cause the cartridge to disengage from the prosthesis. The systems and methods optionally include a trial implant and/or an osteotome for trialing prior to implantation of the prosthesis.
