Abstract
Systems and methods for treating a blood clot positioned within a blood vessel are disclosed. In one embodiment, a balloon member is positioned on a distal end region of a catheter and an ultrasound emitting element is positioned within the balloon member and arranged for actively emitting ultrasound. In some exemplary embodiments, the disclosure provides a multi-wall balloon member and a multi-lumen catheter with at least one and/or all cavities of the balloon member arranged for heat transfer with the ultrasound emitting element. The disclosure also provides catheter arrangements with an ultrasound emitting element arranged to heat tissue adjacent to the balloon member. Additionally, in some embodiments, at least one and/or all walls of the balloon member have apertures arranged to release a therapeutic agent such as a thrombolytic drug.
