1. A micropuncture kit for direct access into a lumen of a blood vessel, the kit comprising:
a micropuncture access needle comprising a proximal hub coupled to an elongate shaft defining an inner lumen and a visible depth indicator positioned on the elongate shaft a distance away from a distal tip of the elongate shaft;
a guidewire positionable through the inner lumen of the micropuncture access needle, the guidewire comprising a distal tip and at least one visible depth indicator on the guidewire a distance away from the first landmark of the guidewire; and
a microaccess cannula comprising an elongate body defining an inner lumen and a plurality of visible depth indicators formed on the elongate body, wherein each of the plurality of visible depth indicators identifies a distance from a distal tip of the cannula to a respective depth indicator;
wherein alignment of a first visible depth indicator of the at least one visible depth indicator positioned on the guidewire with a proximal edge of the cannula provides a visual indication to a user that the first landmark of the guidewire is aligned with the distal tip of the cannula;
wherein alignment of a second visible depth indicator of the at least one visible depth indicator positioned on the guidewire with a proximal edge of the cannula provides a visual indication to a user that the first landmark of the guidewire is aligned with the distal tip of the micropuncture access needle;
wherein alignment of a third visible depth indicator of the at least one visible depth indicator positioned on the guidewire with a proximal edge of the cannula provides a visual indication to a user that the first landmark of the guidewire positioned distally of the distal tip of the micropuncture access needle by a predetermined distance indicated by the third visible depth indicator.
