Patent ID: 7588591

Claim:
An interspinous implant for insertion into an interspinous space located between adjacent first and second vertebral bodies, the implant comprising: first and second elongated, non threaded pins for insertion into the interspinous space between the spinous processes of said adjacent first and second vertebral bodies, the first elongated pin adapted to contact the spinous process of the first vertebral body, the second elongated pin adapted to contact the spinous process of the second vertebral body, each pin having a longitudinal axis, a first end, and a second end, the first pin being parallel to the second pin; and first and second longitudinal parts, each of the first and second longitudinal parts having a longitudinal axis extending transversely to the longitudinal axis of the first and second pins, and each with an apposition surface directed transversely to the longitudinal axis of the first and second pins for contacting said spinous processes of said two adjacent vertebral bodies, each of the first and second longitudinal parts having a first end and a second end, wherein each longitudinal part is connectable with an end of the first and second pins so that the apposition surfaces are facing toward one another, and wherein each of the first and second longitudinal parts having an opening and an elongated hole, said elongated hole extending generally parallel to the longitudinal axes of the first and second longitudinal parts, respectively, the first and second ends of the first pin being firmly connected within the openings of the first and second longitudinal parts, respectively, so that the first pin is stationary with respect to the first and second longitudinal parts and the first and second ends of the second pin are receivable within the elongated holes of the first and second longitudinal parts, respectively, so that the second pin is movable within the elongated holes formed in the first and second longitudinal parts generally parallel to the longitudinal axis of the first and second longitudinal parts and so that the second pin is moveable with respect to the first pin; and wherein the elongated holes include a plurality of teeth formed on an inner peripheral surface of the elongated holes, said plurality of teeth engaging an outer circumference surface of the first and second ends of the second pin so that the second pin is selectively immobilizable relative to the first and second longitudinal parts, wherein the first end of the first and second pins include a pointed tip, and wherein each of the first and second longitudinal parts are configured in the shape of a panel.
