A catheter assembly includes a catheter body that extends from a distal end to
a proximal end. The catheter body includes a delivery lumen, and an actuator lumen,
where the actuator lumen extends from a position near or at the distal end to an
intermediate portion that does not extend through the proximal end of the catheter
body. The catheter body optionally includes an accessory lumen that extends from
at or near the distal end and terminates at an intermediate portion that does not
extend through the proximal end surface of the catheter body, for example, on a
side wall.
