1. A cannula, comprising:
an elongate body extending along a longitudinal axis, the elongate body having a proximal end, a distal end, and a lumen extending through the elongate body between openings at the proximal and distal ends; and
a first flange member that extends at least partially around at least one of the openings, the first flange member having a first surface, wherein at least a portion of the first surface is reflective;
wherein an angle at which the first flange member is oriented relative to the longitudinal axis of the elongate body is adjustable; and
wherein the angle is adjustable using an adjustment device having an inner lumen that is configured to receive the elongate body therein, and, with the elongate body configured to extend through tissue such that the proximal end of the elongate body is on a first side of the tissue and the distal end of the elongate body is on a second side of the tissue, the adjustment device is configured to move along the longitudinal axis of the elongate body such that engagement of the adjustment device with the first flange member causes the angle to be adjusted.
