1. An end effector assembly for a tissue removal device, the end effector assembly comprising:
an outer shaft defining a proximal end portion and a distal end portion, wherein a window is defined through the distal end portion of the outer shaft;
a hub housing engaged with the proximal end portion of the outer shaft; and
a distal driver disposed within the hub housing and configured to rotate relative to the hub housing, wherein the distal driver defines an internal lumen and at least one opening in communication with the internal lumen,
wherein an outflow path is defined from the window through the outer shaft, into an interior of the hub housing, through the at least one opening of the driver, and through the internal lumen of the distal driver, the outflow path adapted to connect to a source of suction.
