Abstract
A releasable coupling mechanism for coupling a delivery catheter and a dilator. The delivery catheter comprising a delivery catheter hub at the proximal end and the dilator comprising a dilator hub at the proximal end. The proximal end of the delivery catheter hub comprises a coupling member for releasably receiving a raised portion which is positioned at a distal end of the dilator hub. The coupling member has a pair of engagement members positioned on opposing sides of the coupling member and configured to releasably engage the raised portion. The delivery catheter hub further comprising at least one indicia on the housing. The indicia indicate 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.
