Claim Text:
1. An infusion catheter, comprising: a catheter body having a proximal end, a distal end, and at least a first lumen and a second lumen extending therethrough; an infusion tube having a proximal end, a distal end, and at least one lumen disposed therethrough adapted to deliver fluid to a body lumen, the proximal end of the infusion tube being connected to the distal end of the catheter body such that the first lumen of the catheter body is in fluid communication with the lumen of the infusion tube; and a central member having a distal end connected to the distal end of the infusion tube, a proximal end, and a proximal portion slidably received in the second lumen of the catheter body, the infusion tube being disposed relative to the central member such that axial advancement of the central member relative to the catheter body radially collapses the infusion tube over the central member and axial retraction of the central member relative to the catheter body radially expands the infusion tube relative to the central member.
