Abstract
An apparatus for performing an endovascular procedure using ultrasonic energy includes a catheter comprising a wave guide including an expandable portion for delivering the ultrasonic energy from a source for performing the endovascular procedure. The expandable portion may comprise a plurality of wires formed of a shape memory material. A retractable sheath may be provided for receiving the plurality of wires in the non-deployed position and for being withdrawn to expose the wires in the deployed position. A linear actuator for moving the plurality of wires in a longitudinal direction or a rotary actuator for rotating the plurality of wires may also be provided.
Claims20
An apparatus for performing an endovascular procedure, comprising:
- an ultrasonic transducer;
- and
- a catheter comprising a wave guide for delivering the ultrasonic energy from the transducer for performing the endovascular procedure, the wave guide including an expandable portion.
An apparatus for performing an endovascular procedure using an ultrasonic transducer, comprising:
- a catheter including a waveguide for transmitting the ultrasonic energy from the source, the wave guide comprising a core including a tip and an expandable portion supported by the core and positioned proximally of the tip.
An apparatus for performing an endovascular procedure, comprising:
- a catheter that does not carry a balloon;
- and
- a wave guide including a core and a plurality of wires fixedly mounted to the core, the wires being expandable from a non-deployed position at least partially closer to the core to a deployed position at least partially spaced from the core.
