Abstract
An intravascular device such as an introducer sheath or a balloon catheter, and methods for use thereof, comprising an elongate member having a proximal end and a distal end and a first lumen and a second lumen. The first lumen communicates with a first proximal opening at the proximal end of the elongate member and with a distal opening at the distal end of the elongate member. The second lumen terminates distally and communicates with the first lumen at a location proximal of the first distal opening and has a proximal opening located proximally therefrom. One or more perfusion openings may be located in the device to allow blood flow therethrough. The proximal opening of the second lumen may be located distally of the proximal opening of the first lumen. A balloon may be located on a distal portion of the elongate shaft.
