1. A hysteroscopy system comprising:
a scope; and
a flow device positionable within the scope, the flow device having a distal end portion and a proximal end portion and defining a longitudinal axis extending between the distal and proximal end portions, the flow device including:
an outer tube defining a channel extending through the outer tube, the channel having a non-circular cross-section;
a first inner tube disposed within the channel, the first inner tube having a distal end portion and a proximal end portion; and
a second inner tube disposed within the channel, the second inner tube having a distal end portion and a proximal end portion, wherein the first and second inner tubes cooperate to conform to the non-circular cross-section of the channel,
wherein one of the first or second inner tubes is configured for fluid inflow and the other of the first or second inner tubes is configured for fluid outflow, and
wherein the distal end portion of the first inner tube is longitudinally offset from the distal end portion of the second inner tube.
