System and method for endoluminal and translumenal therapy
First Claim
1. A system for conducting a denervation of the neural plexus adjacent the renal artery of a patient, comprising:
- a. a first elongate member operatively coupled to a testing element;
b. a second elongate member having a distal portion coupled to an ablative element; and
c. a controller configured to;
1) activate an ablative element to selectively denervate a portion of the neural plexus which is positioned adjacent the ablative element;
2) monitor a level of a compound in blood sampled from the testing element of the first elongate member; and
3) modulate the activation of the ablative element based at least in part upon the level of renin monitored using the testing element.

Abstract
A system for conducting a denervation of the neural plexus adjacent the renal artery of a patient comprises a first elongate member operatively coupled to a testing element, a second elongate member having a distal portion coupled to an ablative element, and a controller configured to: activate an ablative element to selectively denervate a portion of the neural plexus which is positioned adjacent the ablative element; monitor a level of a compound in blood sampled from the testing element of the first elongate member; and modulate the activation of the ablative element based at least in part upon the level of renin monitored using the testing element.

11. A method for conducting a denervation process upon the neural plexus adjacent the renal artery, comprising:
-
a. navigating an ablative element adjacent to a portion of the neural plexus; b. navigating a testing element into the renal vein; c. controllably denervating the portion of the neural plexus; d. utilizing the testing element to detect a compound secreted by a kidney into the renal vein; and e. determining whether further denervation of the portion of the neural plexus is required based at least in part upon the detection of the compound. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A method for conducting a denervation of the neural plexus adjacent the renal artery, comprising:
-
a. creating a neural plexus anatomical map by repeatedly moving, capturing, and assembling image data from an OCT fiber adjacent various portions of the renal artery adjacent the neural plexus; b. navigating an ablative element adjacent to a targeted portion of the neural plexus that is targeted, at least in part, based upon the neural plexus anatomical map; and c. controllably denervating the targeted portion of the neural plexus by activating the ablative element. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)

27. A system for conducting a denervation of the neural plexus adjacent the renal artery, comprising:
-
a. an OCT imaging fiber having a proximal end coupled to an interferometer and a distal end configured to capture image information pertinent to nearby tissue structures; b. an elongate member configured to be navigated into the renal artery, the elongate member having a distal portion that is coupled to both the distal end of the OCT imaging fiber and an ablative element configured to controllably ablate nearby tissue structures when activated by an operator; wherein the interferometer is configured to receive signals from the OCT imaging fiber and present images to an operator based at least in part upon the signals, the images being indicative of location and depth of the nearby tissue structures relative to the distal end of the OCT imaging fiber. - View Dependent Claims (28, 29, 30, 31, 32, 33)
