Abstract

An introducer comprises a sheath, a guide rod, at least one wire stabilization guide, and a loop actuation wire for locating within a wound opening during a medical procedure and during closure of the wound. The elongated members may be actuated to form a loop, or the wire stabilization guides may be adapted loop actuation wire is threaded into the slot and comprises at least a first end and a loop portion. The first end is slidably disposed through the wire stabilization guide, and the loop portion is disposed so that, when the sheath is approximated to a wound site, the loop portion is approximated to tissue surrounding the wound site to hold the sheath approximately centered on the wound site. A method for identifying the depth of insertion of a transluminal device into an artery or vein based on the presence of pressurized blood internal to the vessel and the absence of pressurized blood external to the vessel is also provided.
