(EN) INTERSPINOUS PROCESS IMPLANTS HAVING DEPLOYABLE ENGAGEMENT ARMS
(FR) IMPLANTS INTERVERTÉBRAUX COMPORTANT DES BRAS D'ENCLENCHEMENT DÉPLOYABLES
Abstract
(EN)
Spinal implants include an elongated body portion dimensioned and configured for percutaneous introduction into a target interspinous process space, at which interspinous distraction and/or spinal fusion are desired. The body portion can include a threaded outer surface, or alternatively a smooth surface. The body portion can include one or more interior cavities, and can include deployable engagement members adapted and configured to move in tandem between a stowed position retracted within the interior cavity of the body portion and a deployed position extended from the interior cavity of the body for engaging adjacent spinous processes. An internal drive assembly for selectively moving the engagement members from the stowed position to the deployed position can be provided, as can a elements for locking the engagement members in a deployed position.
(FR)
L'invention porte sur des implants vertébraux comprenant une partie corps allongée dimensionnée et configurée pour l'introduction percutanée dans un espace intervertébral cible, au niveau duquel on souhaite une distraction intervertébrale et/ou une fusion vertébrale. La partie corps peut comprendre une surface extérieure filetée, ou en variante une surface lisse. La partie corps peut comprendre une ou plusieurs cavités intérieures, et peut comprendre des éléments d'enclenchement déployables adaptés et configurés pour se déplacer en tandem entre une position de fixation rétractée dans la cavité intérieure de la partie corps et une position déployée s'étendant à partir de la cavité intérieure du corps pour un enclenchement intervertébral adjacent. Un ensemble entraînement intérieur destiné à déplacer sélectivement les éléments d'enclenchement de la position de fixation à la positon déployée peut être fourni, ainsi que des éléments de verrouillage des éléments d'enclenchement dans une position déployée.
