Abstract

The disclosure includes a balloon guiding sheath including an elongated sheath having a proximal end, a distal end, an inner tube and an outer tube both extending between the proximal end and the distal end, an access port located adjacent the proximal end, a distal port located adjacent the distal end, and a working lumen extending through the elongated sheath between the access port and the distal port. The balloon guiding sheath may include an inflatable balloon located on an outer surface of the elongated sheath adjacent the distal end, and at least one vent hole located between an outer surface of the elongated sheath and an inner surface of the inflatable balloon. The at least one vent hole may be configured to allow media to flow from the inflatable balloon to an external portion outside the balloon guiding sheath.
