A rapid exchange sheath comprising an elongate tubular member, a
guidewire, and support wire having an expandable filter at a distal end.
The guidewire passes through a first opening at a distal end of the
tubular member and a second opening a short distance proximal from the
distal end. The support wire is received in a lumen of the tubular
member, or, in certain embodiments, extends proximally through a third
opening a short distance proximal from the distal end. Methods of using
the sheaths for deploying and/or exchanging medical device(s) in a
patient's vessel are also disclosed.
