Sheath-in-Sheath Technique for Exteriorization of Body Floss Wire

In this technique, we describe the insertion of a second sheath into the primary sheath containing a guidewire that is meant to be exteriorized. The second sheath serves to open the valve of the primary sheath and creates a water-tight chamber for the guidewire to enter. The second sheath is then removed, exposing the successfully exteriorized guidewire. This technique is an useful adjunct to conventional guidewire exteriorization techniques during body floss procedures.
