The handheld devices also include a rigid cannula that includes a distal end and a proximal end, where the rigid cannula is coupled to the handle assembly along the proximal end. The handheld devices further include an inflatable balloon coupled to an outside of the rigid cannula proximate to the distal end, an inflation lumen at least partially disposed along the rigid cannula and in fluid communication with the inflatable balloon and the inflation mechanism, and an aspiration lumen at least partially disposed along the rigid cannula and includes an aspiration port proximate to the distal end.
