Systems and methods for trans-esophageal sympathetic ganglion recruitment
A method may include positioning a catheter, including at least one electrode, within an esophagus such that the electrode is proximate to at least one sympathetic ganglion. The methods may further include recruiting the sympathetic ganglion via an electrical signal, monitoring the recruitment of the sympathetic ganglion, and, based on the monitoring the recruitment of the sympathetic ganglion, adjusting the electrical signal from the at least one electrode.
1. A method of treatment, the method comprising:
positioning a catheter within the esophagus, the catheter including at least one electrode and a feeding tube, wherein the catheter is positioned so that the at least one electrode is proximate to at least one sympathetic ganglion; and
recruiting the at least one sympathetic ganglion via an electrical signal from the at least one electrode.
2. The method of claim 1 , wherein recruiting the at least one sympathetic ganglion includes recruiting a left stellate ganglion and a right stellate ganglion.
3. The method of claim 1 , wherein the at least one electrode includes a first electrode and a second electrode; and
the catheter includes an intermediate section operable to radially expand from a contracted state to an expanded state.
4. The method of claim 3 , wherein the first electrode and the second electrode are disposed on the intermediate section.
5. The method of claim 3 , wherein the intermediate section is biased to the expanded state.
6. The method of claim 1 , wherein the recruiting step occurs while the catheter is positioned in the esophagus.
7. A method of treatment, the method comprising:
positioning a catheter within the esophagus, the catheter comprising:
an intermediate section operable to radially expand from a contracted state to an expanded state; and
a plurality of electrodes;
wherein at least two of the plurality of electrodes are farther displaced from each other when the intermediate section is in an expanded state than when the intermediate section is in a contracted state;
wherein positioning the catheter within the esophagus includes positioning at least one electrode proximate to at least one sympathetic ganglion; and
recruiting the at least one sympathetic ganglion via an electrical signal from the at least one electrode.
8. The method of claim 7 , wherein the recruiting step occurs while the catheter is positioned in the esophagus.
9. The method of claim 7 , wherein the catheter further includes a feeding tube.
10. The method of claim 7 , wherein the intermediate section is biased to the expanded state.
11. The method of claim 7 , wherein the intermediate section includes at least two arms.
12. The method of claim 11 , wherein the plurality of electrodes are disposed on each of the at least two arms.
