Abstract

Implementations of the present disclosure provide an access tube including a wall structure and an optional handle extending from the wall structure. Selectively weakened areas facilitate selective resection of the wall structure to reveal windows that accommodate lateral intrusions by surrounding anatomical structures and/or provide increased access to an intervertebral disc. For example, a first distal weakened portion is configured to form a first window to afford lateral intrusion of a spinous process. A second distal weakened portion is configured to form a second window to afford lateral intrusion of facet. A proximal weakened portion is configured to afford additional angular access on a proximal end of the tube.
