  • Method and apparatus for implanting a hydrogel prosthesis for a nucleus pulposus
    Patent number: 8475532
    Abstract: An instrument for inserting an elongated hydrogel prosthesis into an intervertebral disc includes an insertion cannula that is inserted through the annulus fibrosus of an intervertebral disc to provide access to the nucleus region of the disc, an elongated hydrogel prosthesis packaged within a tubular container adapted to be coupled to a proximal end of the insertion cannula, and a source of fluid pressure adapted to be coupled to a proximal end of the tubular container. Auxiliary instruments for use in convenient insertion of the insertion cannula through the nucleus pulposus and providing for a complete and controlled passage of the hydrogel prosthesis through the insertion cannula are provided in a kit with the insertion cannula.
    Type: Grant
