摘要：
A micropuncture kit for direct access of a surgically exposed vessel using direct visual guidance includes a micropuncture access needle having 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. The kit includes an access guidewire sized to be received through the inner lumen of the micropuncture access needle and a microaccess cannula having an elongate body defining an inner lumen and a plurality of visible depth indicators formed on the elongate body. The guidewire includes a distal tip and at least one visible depth indicator positioned on the access guidewire a distance away from the distal tip of the guidewire. Each of the plurality of visible depth indicators identifies a distance from a distal tip of the cannula. Related systems, devices and methods are provided.
