Abstract

An intravascular catheter and related methods of use or manufacture are disclosed. The catheter includes an outer tubular member having a proximal end and a distal end, and an inner tubular member having a proximal end and a distal end. An inflatable balloon have a proximal end waist coupled to the outer tubular member adjacent to the distal end thereof, and a distal end waist coupled to the inner tubular member adjacent to the distal end thereof. The balloon includes an interior surface, an exterior surface, and a lumen defined by the interior surface. The balloon further includes at least one section extending from the interior surface of the balloon to the exterior surface of the balloon. A transmitter is disposed about the inner tubular member. In addition to the above, the proximal end waist is coupled to the outer tubular member such that an inflation fluid exits the balloon.
