Abstract
Endovascular apparatus for determining the condition of a vessel in a body comprises an elongate waveguide element such as a wire and an activation unit comprising a source of ultrasonic energy to activate the waveguide element, hence transmitting ultrasonic energy to an active distal section of the waveguide element. A signal acquisition system acquires feedback signals from the apparatus for interpretation of vessel condition. The signal acquisition system comprises at least one acoustic sensor for acquiring acoustic feedback signals generated by the apparatus when the waveguide element is activated. Data sets may be generated from acoustic and non-acoustic feedback signals and combinations of, or comparisons between, those data sets can characterise the condition of the vessel, including any lesion such as a blockage in the vessel.
