Beschreibung
Zusammenfassung:	A tissue treatment catheter and system include a catheter shaft sized and shaped for delivery through a radial artery to a blood vessel of a patient. The catheter shaft has several lumens, including a guidewire lumen, a cable lumen, and one or more fluid lumens. A stiffening web extends from the guidewire lumen and is thicker than an outer wall of the catheter shaft. The tissue treatment catheter and system include an ultrasound transducer, a balloon surrounding the ultrasound transducer, and a single electrical cable electrically connected to the ultrasound transducer to deliver sufficient electrical energy during sonication to the transducer such that the transducer thermally induces modulation of neural fibers surrounding the blood vessel sufficient to improve a measurable physiological parameter corresponding to a diagnosed condition of the patient. Other embodiments are described and claimed.
