Abstract
Medical devices and methods for making and using the same are disclosed. An example method may include renal-denervation treatment method. The method may include delivering an RF energy treatment to a tissue proximate a renal artery using a catheter assembly of a renal denervation catheter system. The denervation system may include an RF energy generator coupled with the catheter assembly by a controller. The method may also include applying neural activity stimulation to the tissue proximate the renal artery using the catheter assembly, assessing stimulated neural activity response of the tissue using the catheter assembly, and determining a parameter of the RF energy treatment based on the assessed neural activity.
