Systems and methods for treating dysfunctions in the intestines and rectum that adapt to the anatomic form and structure of different individuals

1. A kit for the treatment of fecal incontinence comprising

a first handle component contained in a first package;

a first barrel structure contained in the first package as a separate unit from the first handle component and capable of being attached to the first handle component by a user, said first barrel component sized and configured with a first dimension conducive for advancement into an anal canal having a first anatomic morphology, the first barrel structure carrying an electrode sized and configured to be coupled to a source of tissue ablation energy to be applied through the electrode to form a lesion, the first barrel structure including a transparent side wall visualized by a direct line of sight from an end portion of the first barrel structure,

a second barrel structure contained in the first package as a separate unit from the first handle component and first barrel structure and capable of being attached to the first handle component by a user independently and alternatively of said first barrel structure, said second barrel component sized and configured with a second dimension different than the first dimension, the second dimension being conducive for advancement into an anal canal having a second anatomic morphology different than the first anatomic morphology, the second barrel structure carrying an electrode sized and configured to be coupled to a source of tissue ablation energy to be applied through the electrode to form a lesion, the second barrel structure including a transparent side wall visualized by a direct line of sight from an end portion of the second barrel structure,

instructions for using either of the selected first or second barrel structure to treat an individual comprising assessing an anatomic morphology of an anal canal of an individual to be treated; selecting one of the first and second barrel structures based upon the assessed anatomic morphology, inserting the selected barrel structure into the anal canal with the electrode retracted within the selected barrel structure; visualizing by the direct line of sight through the transparent side wall of the selected barrel structure the dentate line and the targeted tissue region; while visualizing, aligning the electrode in a desired location in the targeted tissue region above the dentate line; advancing the electrode to penetrate tissue at or near a sphincter; and applying energy through the electrode to create a lesion in the sphincter.

2. A kit according to claim 1

wherein the first handle component includes a frame component.

3. A kit according to claim 1

wherein the instructions include coupling the selected barrel structure to the handle component prior to inserting the selected barrel structure into the anal canal.

4. A kit according to claim 1

wherein the instructions include aspirating fluid at or near the sphincter.

5. A kit according to claim 1

wherein the instructions include sensing tissue temperature during creation of the lesion.

6. A kit according to claim 1

wherein the instructions include manipulating the selected barrel structure to create a composite lesion pattern at or near the sphincter.

7. A kit for the treatment of fecal incontinence comprising;

a first handle component;

a first barrel attachable to the first handle component, the first barrel having a first barrel size and including a temperature sensing device and an electrode to provide energy to create a lesion pattern to treat fecal incontinence;

a second barrel attachable to the first handle component, the second barrel having a second barrel size and including a temperature sensing device and an electrode to provide energy to create a lesion pattern to treat fecal incontinence;

wherein either the first or second barrel is selectively attachable to the first handle component by a user to enable the user to select one of the two different barrel sizes for attachment to the first handle component.

8. A kit according to claim 7 , wherein each barrel includes electrodes movable within the barrel.

9. A kit according to claim 8 , wherein the first and second barrels are configured for single use.

10. A kit according to claim 7 , wherein the first handle component includes a frame component extending transversely to a handle, and the first and second barrels include an elongated slot to form a canopy configuration, the first and second barrels attachable to the frame component.

11. A kit according to claim 10 , wherein the first and second barrels are attachable to a slide on track of the frame component.

12. A kit according to claim 10 , wherein an attached barrel and frame component have a round or oval cross section.
