Abstract
The invention is generally directed to an intraluminal catheter systems including an elongated shaft having proximal and distal shaft sections, and an inflatable member disposed on the distal shaft section and having an interior chamber. A guidewire receiving lumen extends along at least a portion of the proximal shaft section and at least a portion of the distal shaft section and extends distally to the shaft distal end. An inflation lumen extends along at least a portion of the proximal shaft section and at least a portion of the distal shaft section to a point proximal to a shaft distal end and is in fluid communication with the inflatable member interior chamber. The proximal shaft section has multiple non-concentric lumens with at least one lumen forming at least a portion of the guidewire receiving lumen and at least one lumen forming at least a portion of the inflation lumen.
