1. An apparatus for management of fecal incontinence, said apparatus comprising:
- means for blocking passage of stool from a rectal vault by use of an inflatable balloon;
means for detecting an electrically conductive path that occurs between at least two electrodes when they come into contact with fecal matter;
non-conductive sleeve surrounding said electrodes; and
means for alarming a user or caregiver upon detection of said electrically conductive path, thereby alerting the user or caregiver of a need to evacuate the rectal vault; and
wherein a moisture trace across said electrodes completes a voltage divider and causes a comparator to change states.

Abstract
An apparatus, and corresponding method, for management of fecal incontinence comprising a catheter having at least two electrodes and an inflatable balloon, a non-conductive sleeve surrounding the electrodes, and an alarm box, wherein the catheter is insertable into a rectal vault and is inflatable to serve as a block to passage of stool and wherein moisture sensed by the electrodes triggers the alarm box and thereby notifies a user that fecal material has entered the rectal vault.

10. A method for management of fecal incontinence, the method comprising the steps of:
-
blocking passage of stool from a rectal vault by use of an inflatable balloon;
detecting an electrically conductive path that occurs between at least two electrodes when they come into contact with fecal matter;
employing a non-conductive sleeve surrounding the electrodes; and
alarming a user or caregiver upon detection of the electrically conductive path, thereby alerting the user or caregiver of a need to evacuate the rectal vault; and
wherein in the detecting step a moisture trace across the electrodes completes a voltage divider and causes a comparator to change states. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

- 19. An apparatus for management of fecal incontinence comprising a catheter having at least two electrodes and an inflatable balloon, a non-conductive sleeve surrounding said electrodes, and an alarm box, wherein the catheter is insertable into a rectal vault and is inflatable to serve as a block to passage of stool and wherein moisture sensed by said electrodes triggers said alarm box and thereby notifies a user that fecal material has entered the rectal vault, and wherein an integrated circuit is built into said catheter, said integrated circuit providing a means to monitor an amount of time that the catheter is in use.
- 21. An apparatus for management of fecal incontinence comprising a catheter having at least two electrodes and an inflatable balloon, a non-conductive sleeve surrounding said electrodes, and an alarm box, wherein the catheter is insertable into a rectal vault and is inflatable to serve as a block to passage of stool and wherein moisture sensed by said electrodes triggers said alarm box and thereby notifies a user that fecal material has entered the rectal vault, wherein said non-conductive sleeve is porous but impedes intrusion of moisture onto said electrodes, thereby allowing sensitivity of said alarming means to be tailored to different stool consistencies and reducing occurrences of false alarms during insertion, and wherein said sleeve comprises an external support flange with flexible attachment guides configured so that when said balloon is inflated, said attachment guides deform, causing said external support flange and said balloon to move closer to each other and serving to seat said balloon at an anorectal line.

23. A method for management of fecal incontinence, the method comprising the steps of:
-
blocking passage of stool from a rectal vault by use of an inflatable balloon;
detecting an electrically conductive path that occurs between at least two electrodes when they come into contact with fecal matter;
employing a non-conductive sleeve surrounding the electrodes;
alarming a user or caregiver upon detection of the electrically conductive path, thereby alerting the user or caregiver of a need to evacuate the rectal vault; and
monitoring an amount of time that the catheter is in use. - View Dependent Claims (24)

25. A method for management of fecal incontinence, the method comprising the steps of:
-
blocking passage of stool from a rectal vault by use of an inflatable balloon;
detecting an electrically conductive path that occurs between at least two electrodes when they come into contact with fecal matter;
employing a non-conductive sleeve surrounding the electrodes; and
alarming a user or caregiver upon detection of the electrically conductive path, thereby alerting the user or caregiver of a need to evacuate the rectal vault; and
wherein in the employing step the non-conductive sleeve is porous but impedes intrusion of moisture onto the electrodes, thereby allowing sensitivity of alarming to be tailored to different stool consistencies and reducing occurrences of false alarms during insertion; and
wherein the sleeve comprises an external support flange with flexible attachment guides configured so that when the balloon is inflated, the attachment guides deform, causing the external support flange and the balloon to move closer to each other and serving to seat the balloon at an anorectal line. - View Dependent Claims (26)
