IMPLANT FOR SEALING A DEFECT IN THE ANULUS FIBROSUS OF AN INTERVERTEBRAL DISC

摘要

The invention relates to an implant (1) for sealing a defect (7c) in the annulus fibrosus (7a) of an intervertebral disc (7), comprising a retaining portion (3) for introducing into the defect (7c), a flexible sealing element which is connected to an inner end of the retaining portion, and a securing element (2) which is connected to the outer end of the retaining portion and which can be fixed to a vertebra (8) adjoining the intervertebral disc in order to hold the retaining portion (3) in a fixed position. According to the invention, this is achieved in that a securing limb (2), which is angled relative to the longitudinal axis of the retaining portion, is arranged on the outer end of the retaining portion (3), said securing limb being designed for laterally contacting a bony structure of a vertebra adjacent to the intervertebral disc and being securable on the vertebra by means of a fixing element which can be moved relative to the securing limb. The sealing element has inner reinforcements.
