A curvilinear spinal access device having an expandable working portal. The device includes a slide having a channel with an open top and a movable top sized to cover the open top of the channel forming an expandable working portal with a proximal end and a distal end. The movable top can be moved between a closed position and an open position, wherein in the closed position the movable top blocks direct visualization between the proximal end and the distal end of the expandable working portal and in the open position movement of the movable top results in direct visualization from the proximal end to the distal end of the expandable working portal.

Curvilinear spinal access method and device

An interbody spacer is provided. The spacer includes a housing having a top portion, a bottom portion, and a plurality of side portions disposed between the top portion and the bottom portion, a midline portion configured to be disposed across at least one of the top portion and the bottom portion of the housing, an opening disposed between the top portion and the bottom portion, and a grooved channel disposed in at least one of the plurality of side portions. The top and bottom portions are configured to include a plurality of projections configured to protrude away from the top and bottom portions.

Interbody spacer

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.
