Abstract: A system for treating a vascular region includes an elongate catheter shaft having a distal end region, with an inner lumen formed in the elongate shaft and a fluid delivery lumen formed in the elongate shaft adjacent to the inner lumen. A treatment core is disposable within the inner lumen, and has one or more ultrasound transducers disposable adjacent to the distal end region of the elongate catheter shaft, the one or more ultrasound transducers including a proximal-most ultrasound transducer. The fluid delivery lumen is adapted such that fluid passing through the fluid delivery lumen exits the fluid delivery lumen at a position proximal to the proximal-most ultrasound transducer.

Abstract: A first tubular body having a first longitudinal axis extending centrally through the tubular body includes at least one delivery port extending through a wall of the first tubular body. A second tubular body having a second longitudinal axis extends through the second tubular body, the first and second longitudinal axes being displaced from each other such that an asymmetrical longitudinally extending gap is formed between an outer surface of the second tubular body and an interior surface of the first tubular body. A temperature sensor forming a thermocouple extending longitudinally within the gap between the first tubular body and the second tubular body. An inner core is positioned within the second tubular body. The inner core includes least one ultrasound element.
