Claims22
A catheter for providing a therapeutic effect to a vessel of a body, comprising:
- an elongated body having a lumen coupled with a drug delivery port through which a drug within the lumen can exit the lumen;
- and
- a plurality of ultrasound elements coupled to the elongated body where each of the plurality of ultrasound elements is separated from an adjacent ultrasound element and at least two of the ultrasound elements are positioned on opposite sides of the drug delivery port and close enough to the drug delivery port that a drug delivered from the drug delivery port is exposed to ultrasound energy delivered from at least one of the ultrasound elements, the delivered drug and ultrasound energy providing the therapeutic effect to the vessel.
