PerQdisc Traditional Feasibility Trial.

The proposed investigation is a multicenter, prospective, traditional feasibility study of the PerQdisc. A minimum of N=5 subjects will be enrolled. Subjects will be enrolled in approximately 2 sites. Data analyses including all enrolled subjects meeting specific criteria will be submitted to the FDA to support a pivotal trial and used in trial planning. This study will evaluate the safety and effectiveness of the PerQdisc device in the treatment of single level discogenic back pain caused by degenerative disc disease (DDD) (L1 to L5).
