Capsule and method for treating or diagnosing the intestinal tract
First Claim
1. A system for treating or diagnosing the intestinal tract comprising:
- an autonomous capsule comprising an acoustic transducer, the transducer being arranged to emit an acoustic signal detectable externally of a patient'"'"'s body as the capsule passes through at least a portion of the intestinal tract;
at least one external acoustic receiver configured to sense the acoustic signal transmitted by the capsule; and
a reference generator arranged to generate a time reference from which the time of the acoustic signal generation is determined.

Abstract
A device and method for mapping, diagnosing and treating the intestinal tract is provided using a capsule passing through the intestinal tract. Further, a capsule tracking system is provided for tracking a capsule'"'"'s location along the length of an intestinal tract as various treatment and/or sensing modalities are employed. In one variation, an acoustic signal is used to determine the location of the capsule. A map of sensed information may be derived from the pass of a capsule. Capsules may be subsequently passed through to treat the intestinal tract at a determined location along its length. One variation uses an electrical stimulation capsule to treat and/or diagnose a condition in the intestinal tract.

40. A system for treating or diagnosing the intestinal tract of a patient comprising:
-
first capsule means for passing through the intestinal tract of a patient; means for tracking the first capsule means, the means for tracking located external to the patient'"'"'s body; an acoustic signal means for transmitting a signal between the first capsule means as it is passing through the intestinal tract of a patient, and the means for tracking; and a location determining means for determining the location of the first capsule on a coordinate system, wherein the location determining means comprises a time differential means for determining the transmission time of the acoustic signal means between the external means and the capsule means. - View Dependent Claims (41, 42, 43)

44. A system for treating or diagnosing the intestinal tract of a patient comprising:
-
a capsule means for emitting a detectable acoustic signal as it passes through at least a portion of the intestinal tract; and receiver means for receiving the acoustic signal external to the patient, the receiver means comprising at least one acoustic sensor; processor means for determining the location of the capsule on a coordinate system based on the acoustic signal received at the receiver means; and
reference means for determining the time lag between emitting the detectable acoustic signal and receiving the acoustic signal at the at least one acoustic sensor.
