Abstract
The present invention is directed to a gauging system and method for using the same for determining the size of a lesion within a patient's body prior to stenting the lesion. In one embodiment the gauging system includes a catheter having an elongated shaft with proximal and distal ends, and an outer sheath formed of a compliant material and disposed about at least a portion of the catheter elongated shaft and being slidable over the same. In another embodiment, the gauging system further includes a radially expandable member formed of the same or different compliant material mounted on a distal section of the shaft and has an interior chamber in fluid communication with an inflation lumen extending within at least a portion of a distal shaft section to a location spaced proximally from the shaft distal end.
