METHODS AND SYSTEMS FOR ABLATION OF THE RENAL PELVIS

摘要

Apparatus, systems, and methods provide access to the renal pelvis of a kidney to treat renal nerves embedded in tissue surrounding the renal pelvis. Access to the renal pelvis may be via the urinary tract or via minimally invasive incisions through the abdomen and kidney tissue. Treatment is effected by exchanging energy, typically delivering heat or extracting heat through a wall of the renal pelvis, or by delivering active substances to ablate a thin layer of tissue lining at least a portion of the renal pelvis to disrupt renal nerves within the tissue lining of the renal pelvis.

主权项

1. A method for inhibiting or modulating the function of renal nerves in a patient's kidney, said method comprising:
introducing an effector into an interior of the kidney or an upper region of an adjacent ureter; and exchanging energy or delivering active substances from the interior of the kidney to ablate a layer of tissue lining at least a portion of the renal pelvis to disrupt renal nerves within tissue and muscle layers lining of the renal pelvis.
