Techniques for placing medical leads for electrical stimulation of nerve tissue
First Claim
Patent Images
1. A method for locating a stimulation electrode within a blood vessel, the method comprising:
- deploying a delivery catheter through a lumen of the blood vessel to a location proximate a target nerve tissue site outside the blood vessel;
advancing the stimulation electrode from within the deployed delivery catheter and into the blood vessel lumen toward the nerve tissue; and
detecting relative positions of the nerve tissue outside the blood vessel and the advanced electrode within the blood vessel lumen by means of a sensor connected to the delivery catheter.

22. A method for implanting a pair of stimulation electrodes, the method comprising:
-
deploying a delivery catheter through a lumen of a blood vessel to a location proximate a target nerve tissue site outside the blood vessel; advancing a first electrode of the pair of stimulation electrodes from within the deployed delivery catheter and into the blood vessel lumen toward the nerve tissue; energizing the advanced, first electrode; detecting relative positions of the nerve tissue outside the blood vessel and the advanced, first electrode within the blood vessel by means of a sensor connected to the delivery catheter, the sensor measuring blood pressure within the blood vessel after energizing the electrode, and the measured blood pressure indicating whether or not the advanced, first electrode is positioned relative to the nerve tissue for effective stimulation thereof; chronically deploying the advanced, first electrode within the blood vessel lumen adjacent the nerve tissue if the measured blood pressure indicates that the advanced, first electrode is positioned for effective stimulation of the nerve tissue; and arranging a second electrode of the pair of electrodes adjacent the nerve tissue such that the pair of stimulation electrodes are arranged in flanking, non-contacting relationship with the nerve tissue. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
