摘要：
A sphenocath including a sheath assembly including a sheath hub with a sheath tube extending therefrom with a passage extending from a proximal end of the sheath hub to a distal end of the sheath tube； a catheter assembly including a catheter hub with a catheter tube extending therefrom with a passage extending from a proximal end of the catheter hub to a distal end of the catheter tube； wherein the catheter assembly passes through the sheath assembly with a portion of the catheter hub engaging a portion of the sheath hub to limit relative rotation between the hubs while permitting relative axial movement such that in an initial non-extended position the distal end of the catheter tube is proximate to the distal end of the sheath tube. A system further including a guidewire is also provided.
