<P>PROBLEM TO BE SOLVED: To provide rapid exchange sheaths which can be advanced over a guidewire and carry an endoluminal medical device to a region of interest and can thereafter be removed from a patient's vessel without requiring a large proximal guidewire segment extending out of the patient's vessel. <P>SOLUTION: The rapid exchange sheath comprises an elongate tubular member 10, the guidewire 20, and support wire 25. The guidewire passes through a first opening 15 at a distal end of the tubular member and a second opening 16 a short distance proximal from the distal end. The support wire is received in a lumen 11 of the tubular member, and extends proximally through a third opening 17 a short distance proximal from the distal end. The support wire is suitable for receiving an endoluminal medical device such as a filter 50 expandable at the distal end. Methods of using the sheaths for deploying and/or exchanging medical device(s) in a patient's vessel are also disclosed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
