INTERSPINOUS PROCESS IMPLANT HAVING A BODY WITH A REMOVABLE END PORTION

摘要

An interspinous process implant is disclosed that includes an elongated threaded implant body defining a longitudinal axis and having a main body portion with opposed proximal and distal end portions, and a removable body portion operatively connected to the proximal end portion of the main body portion, a distal anchor assembly including two deployable anchor blades mounted for pivotal movement between a stowed position located within an interior cavity of the main body portion and a deployed position radially extending from the main body portion, and a proximal anchor assembly including an anchor collar mounted for longitudinal movement along the longitudinal axis of the implant body between a first position spaced apart from the distal anchor assembly and a second position approximated with the distal anchor assembly.
