Abstract
An endovascular apparatus for crossing through an obstruction in a blood vessel comprises: an elongate endovascular element such as a wire; an ultrasonic transducer, mechanically coupled to the endovascular element for ultrasonically exciting a distal tip portion thereof to facilitate the crossing through the obstruction, and one or more damping features, mechanically coupled to the endovascular element to attenuate lateral displacement of the endovascular element at positions away from the distal tip portion.
Claims36
Endovascular apparatus for crossing through an obstruction in a blood vessel, the apparatus comprising:
- an elongate endovascular element,
- a source of ultrasonic energy comprising an ultrasonic transducer, and
- a coupling for, in use, transmitting the ultrasonic energy along the endovascular element from the source to an active tip portion at a distal end of the endovascular element, the coupling being arranged to couple the source to the endovascular element at any of a plurality of discrete operational positions along the length of the endovascular element for said transmission of ultrasonic energy to the active tip portion, the coupling further being arranged to clamp the endovascular element when at any of the operational positions, the endovascular element extending through the coupling and the source and having portions that extend, respectively, proximally and distally from the coupling and the source,
- wherein the endovascular apparatus further comprises damping features that are mechanically coupled to the endovascular element at positions away from the active tip portion to attenuate lateral displacement of the endovascular element proximally and distally of the transducer and to attenuate longitudinal displacement of the endovascular element proximally of the transducer.
