Abstract
A wire guide includes a mandrel that has a proximal portion and a distal portion. A coating having a low coefficient of friction is disposed on at least part of the proximal portion and the distal portion of the mandrel, where a part of the proximal portion and distal portion of the mandrel without the coating indicates a marking on the wire guide. This marking on the wire guide allows a user to determine a trimmable length of a catheter, and the low friction coating enables the user to easily advance the catheter over the wire guide.
