and determining a location of a distal end of the lead in the patient utilizing the accelerometer, wherein the location is not in the heart or pericardium. ### Claim 2 (depends on 1) The method of claim 1, wherein the accelerometer is disposed at a distal end of the lead. ### Claim 3 (depends on 1) The method of claim 1, further comprising: receiving movement information from the accelerometer during advancement of the lead; wherein the determining of the location of the distal end of the lead utilizes the movement information received from the accelerometer. ### Claim 4 (depends on 3) The method of claim 3, wherein the movement information is received continuously during at least a portion of the advancement of the lead. ### Claim 5 (depends on 4) The method of claim 4, further comprising: determining a continuous path taken by the lead based on the movement information; wherein the determining the location of the distal end of the lead in the patient utilizes the determined continuous path. ### Claim 6 (depends on 1) The method of claim 1, further comprising: detecting acoustic pressure waves during the advancing of the lead; wherein determining the location of the distal end of the lead includes comparing the detected acoustic pressure waves with a known model. ### Claim 7 (depends on 6) The method of claim 6, wherein the acoustic pressure waves are generated by an anatomical structure of the patient. ### Claim 8 (depends on 6) The method of claim 6, wherein the anatomical structure of the patient comprises a blood-filled vessel. ### Claim 9 (depends on 6) The method of claim 6, wherein the anatomical structure of the patient is a heart. ### Claim 10 (depends on 1) The method of claim 1, further comprising: generating artificial pressure waves in the patient in a controlled manner; detecting the artificial pressure waves with the accelerometer; wherein the determining of the location of the distal end of the lead includes comparing the detected artificial pressure waves with a known model. ### Claim 11 A cardiac pacing system comprising: a lead configured to electrically couple with a pulse generator and to transmit therapeutic electric pulses to a patient, the at least one lead comprising: at least one accelerometer disposed on the lead and configured to facilitate delivery of the lead to a desired location within a mediastinum of the patient, proximate the heart but not physically in contact with the heart or pericardium; at least one programmable processor; and a non-transitory machine-readable medium storing instructions which, when executed by the at least one programmable processor, cause the at least one programmable processor to perform operations comprising: determining a location of a distal end of the lead in the patient utilizing the accelerometer, wherein the location is not in the heart or pericardium. ### Claim 12 (depends on 11) The cardiac pacing system of claim 11, wherein the accelerometer is disposed at a distal end of the lead. ### Claim 13 (depends on 11) The cardiac pacing system of claim 11, wherein the accelerometer is configured to transmit movement information during advancement of the lead;
