IRREVERSIBLE ELECTROPORATION (IRE) FOR ESOPHAGEAL DISEASE
A method for treating Barrett's esophagus and esophageal cancer by using non-thermal electroporation energy to ablate diseased portions of the esophagus which, in effect, prevents stomach acids and other fluids from entering the esophagus thereby alleviating continued deterioration of the esophagus and allows the columnar cells in the lining of the esophagus to assume their normal physical characteristics and functions and.
1 . A method of treating an esophagus including the steps of:
a. obtaining access to the esophagus, wherein the esophagus contains a diseased region;
b. positioning at least one energy delivery device within the diseased region, wherein the energy delivery device is coupled to an electroporation energy source; and
c. applying electroporation energy to non-thermally ablate a portion of the diseased region.
2 . The method of claim 1 , wherein the step of obtaining access further comprises obtaining access endotracheally.
3 . The method of claim 1 , wherein the step of applying electroporation energy further comprises the application of energy from at least one energy delivery device selected from the group consisting of at least one of electrode balloons, monopolar probes, bipolar probes, multipolar probes, electrode arrays, and any combination thereof.
4 . The method of claim 1 , wherein the step of applying electroporation energy further comprises the application of energy using an electrode balloon.
5 . The method of claim 1 , wherein the step of applying electroporation energy further comprises the application of energy using a perfusing electrode balloon.
6 . The method of claim 1 , wherein the step of applying electroporation energy further comprises the application of energy using an IRE probe.
7 . The method of claim 1 , wherein the step of applying electroporation energy further comprises the application of energy using a catheter and IRE probe.
8 . The method of claim 1 , wherein the step of applying electroporation energy further comprises:
inserting the at least one energy delivery device into the catheter prior to ablation;
retracting the at least one energy delivery device within the catheter after ablation;
moving the catheter;
redeploying the at least one energy delivery device in an adjacent diseased region; and
ablating the adjacent diseased region.
9 . The method of claim 5 , wherein the step of ablating further comprises ablation of the diseased region that is caused by Barrett's esophagus.
10 . The method of claim 7 , wherein the step of ablating further comprises ablation of he diseased region that is caused by esophageal cancer.
11 . The method of claim 5 , further comprising placing the electrode balloon in contact with the inner lining of the esophagus.
12 . The method of claim 8 , wherein the step of ablating further comprises ablation using an energy field strength in the range of 100V/cm to greater than 10,000V/cm.
13 . The method of claim 8 , wherein the step of ablating further comprises ablating the diseased region until bad cells necrose while allowing good cells to regenerate.
14 . The method of claim 13 , wherein the step of ablating further comprises sparing the esophagus from destruction and preserving connective tissue surrounding the esophagus.
15 . The method of claim 1 , wherein the step of applying electroporation energy further comprises applying energy using a flexible device.
16 . The method of claim 8 , wherein the step of applying electroporation energy further comprises applying energy using a flexible device.
