A catheter assembly (1) includes an inner member (12) having a proximal end (15), a distal end (13), and a lumen configured to store a hydrating fluid (28) An outer member (10) has a proximal end (19), a distal end (16), and a lumen configured to receive therein a portion of the inner member (12) The outer member (10) is movable relative to the inner member (12) at least one of between a first position (FIG. 1) preventing fluid (28) from passing out of the at least one drainage opening (14) from within the lumen of the inner member (12) and a second position (FIG. 2) allowing fluid (28) to pass out of the at least one drainage opening (14) from within the lumen of the inner member (12).
