1. A releasable coupling mechanism, comprising:
a dilator, the dilator having a dilator hub positioned at a proximal end of the dilator;
the dilator hub having a raised portion positioned at a distal end of the dilator hub
a delivery catheter, the delivery catheter having a delivery catheter hub positioned at a proximal end of the delivery catheter;
the delivery catheter hub defining a housing;
a coupling member completely enclosed within the housing of the delivery catheter hub, the coupling member having a pair of inwardly protruding engagement members positioned on opposing sides of the coupling member, wherein the inwardly protruding engagement members are configured to releasably engage the raised portion of the dilator hub; and,
at least one indicia located on the housing of the delivery catheter hub, wherein the at least one indicia indicates an orientation of the delivery catheter hub such that the dilator hub disengages from the coupling member by simultaneously deflecting the pair of engagement members.
