  • Ultrasound catheter
    Patent number: 11740138
    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.
