ABSTRACT:
A sheath for facilitating a guide wire exchange is defined by an elongated tubular member having a proximal end, a distal end and a single thru lumen. The sheath also has a proximal insertion opening and a distal insertion opening in communication with the thru lumen. The sheath includes a distal guide segment for "single operator" insertion and a peelable extent for peelably removing the sheath after use. The distal guide segment is formed along a distal portion of the elongated tubular member. The sheath is inserted along a pre-inserted guide wire by inserting a proximal end of the pre-inserted guide wire through a guide lumen of the distal guide segment. The sheath is advanced distally along the pre-inserted guide wire to a desired position and thereafter the pre-inserted guide wire is withdrawn. A re-shaped guide wire or substitute guide wire is inserted through the proximal insertion opening and advanced through the thru lumen of the sheath to a treatment site. The sheath is withdrawn while peelably removing the tubular member from the inserted guide wire.
