A catheter system comprising: (a) a catheter comprising (i) a tube, the tube having (A) a wall with an outer surface , the outer surface having a first cross-sectional area, (B) a lumen , (C) a distal end with one or more openings in communication with the lumen , and (D) a proximal end with an opening in communication with the lumen , (ii) a valve that is operated to be in (A) a closed configuration, wherein fluid does not flow out of the proximal end , or (B) an open configuration in which fluid does flow out of the proximal end ; and (iii) a retainer portion between the distal end and the proximal end , the retainer portion having a maximum cross-sectional area at least 1.5 to 10 times as large as the first cross-sectional area; (b) a catheter mating device comprising: a stem having a proximal end and a distal end ; wherein the distal end includes an apparatus having (i) a first, retracted configuration, and (ii) a second, expanded configuration; the apparatus being configured to be received in the proximal end of the catheter when in its first, retracted configuration, and configured to engage the proximal end of the catheter when in its second, expanded configuration; and (c) a housing connected to the proximal end of the stem , wherein the housing includes a control having a first position and a second position, and the apparatus is in its first, retracted position when the control is in its first position, and the apparatus is in its second, extended position when the control is in its second position, wherein the apparatus comprises a plurality of tips moveable from the first, retracted position to the second, extended position.
