Abstract
A curvilinear spinal access device for performing a procedure on a spine of a patient is disclosed. The device includes a working portal configured to be advanced toward a surgical site located at the spine of the patient. The working portal includes a distal end and a proximate end, a working portal housing having an open interior channel disposed between the distal end and the proximate end, an exterior channel disposed on an outside surface of the working portal housing and between the distal end and the proximate end. The distal end is configured to be disposed at the surgical site and the proximate end is disposed away from the surgical site. The housing has a curved shape defined between the proximate end and the distal end, wherein the proximate end is disposed with respect to the distal end. The working channel is configured to allow advancement of at least one surgical tool and/or at least one implant toward the surgical site.
