Neuromodulation systems and methods for treatment of sexual dysfunction
First Claim
1. A method for treating a human patient diagnosed with erectile dysfunction or premature ejaculation, the method comprising:
- advancing a neuromodulation assembly along an intravascular path to a position within a target blood vessel of a human patient, wherein the neuromodulation assembly is at a distal portion of a treatment device, and wherein the position within the target blood vessel is proximate to neural fibers innervating penile tissue of the human patient;
at least partially disrupting function of the neural fibers innervating the penile tissue by applying thermal energy to the neural fibers via the neuromodulation assembly; and
retracting the neuromodulation assembly along the intravascular path to remove the neuromodulation assembly from the patient after treatment,wherein at least partial disruption of the function of the neural fibers innervating the penile tissue therapeutically treats the diagnosed erectile dysfunction or premature ejaculation.

Abstract
Apparatus, systems, and methods for achieving thermally-induced renal neuromodulation by intravascular access are disclosed herein. One aspect of the present application, for example, is directed to apparatuses, systems, and methods that incorporate a treatment device comprising an elongated shaft. The elongated shaft is sized and configured to deliver a thermal element to a renal artery via an intravascular path. Thermally-induced renal neuromodulation may be achieved via direct and/or via indirect application of thermal energy to heat or cool neural fibers that contribute to renal function, or of vascular structures that feed or perfuse the neural fibers.

6. A method for treating erectile dysfunction in a human patient, the method comprising:
-
transluminally advancing a catheter along an intravascular path to position an energy delivery element of the catheter within a target blood vessel of the patient and adjacent to neural fibers that innervate penile tissue of the patient; at least partially ablating the neural fibers innervating the penile tissue of the patient via the energy delivery element; and retracting the catheter along the intravascular path to remove the neuromodulation assembly from the patient after treatment, wherein at least partially ablating the neural fibers results in a therapeutically beneficial reduction in one or more physiological conditions associated with erectile dysfunction of the patient. - View Dependent Claims (7, 8)

9. A method of treating a human patient diagnosed with erectile dysfunction, the method comprising:
-
intravascularly advancing a neuromodulation assembly along an intravascular path to a position within a target blood vessel of the patient that is adjacent to a target sympathetic nerve of the patient; reducing sympathetic neural activity in the patient by delivering energy to the target sympathetic nerve via the neuromodulation assembly; and retracting the neuromodulation assembly along the intravascular path to remove the neuromodulation assembly from the patient after treatment, wherein reducing sympathetic neural activity therapeutically treats the diagnosed erectile dysfunction. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
