Abstract
The present invention, in some embodiments thereof, relates to a devices and methods for intravascular denervation and assessment thereof and, more particularly, but not exclusively, to devices and methods for renal denervation. Some embodiments of the invention relate to an intravascular catheter configured for ultrasonic ablation of the tissue, comprising a plurality of piezoelectric transceivers. In some embodiments, an intravascular distancing device is provided, the device adapted for obtaining at least a minimal distance between an ultrasound emitting element and a tissue, such as the blood vessel wall. Some embodiments of the invention relate to assessment of renal sympathetic denervation (RSD) treatment effectiveness. Some embodiments of the invention relate to processing echo of signals, such as processing of signals to characterize physical and/or mechanical properties of the blood vessel.
