Abstract:
1. A method for implantation of an electrode at an intended location outside of the lumen of a blood vessel or other anatomical conduit within the a human or veterinary patient, the method comprising the steps of: a) providing a tissue penetrating catheter that comprises i) an elongate catheter body, ii) a hollow tissue penetrator that is moveable from a retracted position within the catheter body to an extended position wherein it extends laterally from the catheter body and iii) an orientation element useable while the penetrator is in its retracted position to determine the lateral direction in which the penetrator will subsequently advance from the catheter body as it is moved to its extended position; b) positioning the catheter body in the blood vessel or other anatomical conduit; c) using the orientation element while the penetrator is in its retracted position to adjust the rotational orientation of the catheter body as needed to substantially ensure that subsequent movement of the penetrator to its extended position will cause the penetrator to enter the intended location where the electrode is to be implanted; d) advancing the penetrator into the intended location where the electrode is to be implanted and, thereafter, e) implanting an electrode at the intended location by at least one of the following procedures:
