Abstract
A method and apparatus for treatment of heart failure, hypertension and renal failure by stimulating the renal nerve. The goal of therapy is to reduce sympathetic activity of the renal nerve. Therapy is accomplished by at least partially blocking the nerve with drug infusion or electrostimulation. Apparatus can be permanently implanted or catheter based.
Claims29
A method for reducing blood pressure in a human patient, the method comprising:
- positioning a nerve modulation device within renal vasculature of the patient and adjacent to a renal nerve of at least one kidney of the patient;
- and
- at least partially blocking the renal nerve of the kidney of the patient by at least partially ablating the renal nerve,
- wherein at least partially blocking the renal nerve results in a therapeutically beneficial reduction in blood pressure of the patient.
A method of treating a disease of a human patient diagnosed with at least one of heart failure, hypertension, acute myocardial infarction, impaired renal function, or chronic renal failure, the method comprising:
- positioning an energy delivery element within a renal blood vessel and proximate to a renal nerve of the patient;
- and
- delivering an energy field via the energy delivery element to modulate neural function of the renal nerve,
- wherein delivering the energy field results in a therapeutically beneficial reduction in blood pressure of the patient.
A method for reducing blood pressure in a human patient, the method comprising:
- intravascularly positioning a nerve modulation device within a renal artery of the patient and adjacent to a renal nerve of the patient;
- at least partially blocking the renal nerve by at least partially ablating the renal nerve,
- wherein at least partially blocking the renal nerve results in a therapeutically beneficial reduction in blood pressure of the patient;
- and
- removing the nerve modulation device from the renal artery after at least partially ablating the renal nerve.
