The device includes a dilator with a hub (38) and an elongated body (36). A locking mechanism (30) is configured to limit a distance a guidewire (28) can be advanced out of a distal end of the dilator. The guidewire has a guidewire stop (92B) being receivable through the elongated dilator body (36). The guidewire lock (30) having at least one member being moveable between an engaged state and a non-engaged state and being biased toward the engaged state in which the guidewire lock interacts with the guidewire. The locking mechanism and the dilator are configured to permit removal of the locking mechanism (30) from the dilator by moving the guidewire (28) axially in a proximal direction relative to the dilator with the guidewire stop abutting at least part of the portion of the locking mechanism that an opening extends through.
