Claim Text:
1. A method for circulating fluid to a target site within a living body, comprising: supplying fluid to the target site via an inlet lumen of a longitudinal member of a circulating device, the longitudinal member including a first sleeve defining a working channel extending therethrough to a distal opening and a second sleeve extending therearound, the first sleeve including a first elongated structure and the second sleeve including a second elongated structure; and withdrawing fluid from the target site via a return lumen of the longitudinal member of the circulating device, the return lumen surrounding the inlet lumen, the fluid being withdrawn through a screen coupled to a distal end of the longitudinal member, the screen including a plurality of openings extending therethrough from a radially inner surface forming a radially outer wall of a distal portion of the return lumen to an outer surface thereof, wherein, in an operative configuration, a distal end of the first sleeve extends distally beyond a distal end of the second sleeve, and is located proximal to a distal tip of the screen, so that an opening of the inlet lumen is adjacent to a distal opening in the screen.
