Claim 10:
11. An access needle assembly, comprising:
an anchoring guidewire including a first orienting feature; and
an access needle including a hollow shaft having a lumen sized and shaped to slidably receive the guidewire therein and having a distal end including a cut surface extending proximally and transversely from a sharpened distal-most tip of the shaft to a beveled smoothed area of the shaft proximal and transverse to the sharpened tip, the beveled smoothed area being positioned and configured to slidably engage the guidewire extended distally out the distal end of the needle so that, as the guidewire is retracted proximally into the needle, the beveled smoothed area slidably engages the guidewire to minimize abrasion to the guidewire, the access needle further including a second orienting feature extending along a distal portion thereof configured to mechanically engage the first orienting feature to maintain the guidewire in a desired rotational orientation relative to the access needle.
