1. An elongate endovascular element for crossing through an obstruction in a blood vessel, the element comprising:
a proximal section;
a distal tip section of smaller diameter than the proximal section; and
a distally-tapering intermediate section extending between the proximal and distal tip sections;
wherein the tapered intermediate section has a length that is substantially λ/2 or a multiple or an even-denominator fraction of λ/2 in the sequence λ/4, λ/8 . . . , where λ is a wavelength of a driving frequency that will produce longitudinal resonance in the element, and wherein the proximal section of the element is marked with a series of longitudinally-spaced location markers, spaced apart from each other by a distance of substantially λ/2, to guide the user in coupling an activation unit for optimal activation of the distal tip section.
