Methods for renal denervation
Various agents are described to denerve, modulate, or otherwise affect the renal nerves and other neural tissue. Also, various delivery devices are described to deliver an agent locally to the renal nerves. The delivery devices are positioned in the renal artery and penetrate into the wall of the renal artery to deliver the agent to the renal nerves. The delivery devices may be used to deliver the agent according to longitudinal position, radial position, and depth of the renal nerves relative to the renal artery. In addition, various methods are described to denervate, modulate, or otherwise affect the renal nerves and other neural tissue.
1. A method for killing targeted renal nerve cells in a mammal, the method comprising:
delivering a cardiac glycoside locally to the renal nerve cells in an amount sufficient to kill the renal nerve cells and treat hypertension in the mammal.
2. The method of claim 1 , wherein the cardiac glycoside is digoxin.
3. The method of claim 2 , wherein the amount is 0.0001 to 10 mM.
4. The method of claim 1 , wherein the cardiac glycoside is proscillaridin.
5. The method of claim 4 , wherein the amount is 0.0001 to 10 mM.
