1. A renal denervation feedback method comprising:
- performing a baseline measurement of intrinsic renal nerve plexus electrical activity at a renal vessel by monitoring compound action potentials;
denervating at least some tissue proximate the renal vessel after performing the baseline measurement;
performing a post-denervation measurement of renal nerve plexus electrical activity at the renal vessel by monitoring compound action potentials, after the denervating; and
assessing denervation of the renal vessel based on a comparison of the baseline measurement and the post-denervation measurement of renal nerve plexus electrical activity at the renal vessel.

Abstract
A renal denervation feedback method is described that performs a baseline measurement of renal nerve plexus electrical activity at a renal vessel; denervates at least some tissue proximate the renal vessel after performing the baseline measurement; performs a post-denervation measurement of renal nerve plexus electrical activity at the renal vessel, after the denervating; and assesses denervation of the renal vessel based on a comparison of the baseline measurement and the post-denervation measurement of renal nerve plexus electrical activity at the renal vessel.

23. A renal denervation feedback system, comprising:
-
at least one denervation member to denervate at least some tissue proximate the renal vessel; at least one measurement member to perform a baseline measurement of intrinsic renal nerve plexus electrical activity at a renal vessel before denervation of at least some tissue proximate the renal vessel and to perform a post-denervation measurement of renal nerve plexus electrical activity at the renal vessel after the denervation, the baseline and post-denervation measurements acquired by monitoring compound action potentials; and a denervation assessment module to assess denervation of the renal vessel based on a comparison of the baseline measurement and the post-denervation measurement of renal nerve plexus electrical activity at the renal vessel. - View Dependent Claims (24, 25)
