Abstract
Disclosed herein is a catheter, which in some embodiments includes a distal section configured to enter a skin insertion site. The distal section can include a tapered junction having one or more dilation structures configured to dilate the skin insertion site. The distal section can further include a distal portion extending from a distal end of the tapered junction, the distal portion having a diameter smaller than a proximal portion of the catheter. In combination, the tapered junction, the one or more dilation structures, and the specific actions of the user urging the catheter into the insertion site can result in an improved fit of the catheter in the insertion site.
