Gastrointestinal capsule and treatment method
First Claim
1. A gastrointestinal capsule (GIC) comprising:
- (a) a capsule housing having a longitudinal axis;
(b) a thrusting mechanism, disposed within said capsule housing, said thrusting mechanism having an active mode, and a passive mode with respect to said active mode,said thrusting mechanism including;
(i) a rotatably mounted eccentric weight,said thrusting mechanism adapted, in said active mode, to rotate said eccentric weight thereby to exert radial forces on said capsule housing, in a radial direction with respect to said longitudinal axis, and(ii) an axial perturbation arrangement including;
a motor;
a motor shaft, disposed at least partially in a direction along said longitudinal axis, said motor shaft operatively connected to, and driven by, said motor; and
a thrusting weight associated with said motor shaft,said axial perturbation arrangement adapted to at least periodically urge said thrusting weight along said motor shaft, to deliver axial forces to said capsule housing,such that when the gastrointestinal capsule is disposed within a gastrointestinal tract of a user, and said thrusting mechanism is in said active mode, the gastrointestinal capsule stimulates a wall of said gastrointestinal tract; and
(c) a battery adapted to power said thrusting mechanism.

Abstract
A gastrointestinal capsule (GIC) including a capsule housing having a longitudinal axis; a thrusting mechanism, disposed within the housing; and a battery adapted to power the and a battery adapted to power the thrusting mechanism; the thrusting mechanism having an active mode, and a passive mode with respect to the active mode, the thrusting mechanism adapted to exert a radial force on the housing, in a radial direction with respect to the axis, such that when the capsule is disposed within a gastrointestinal tract of a user, and the mechanism is in the active mode, the gastrointestinal capsule stimulates a wall of the tract; the active mode including a series of at least two pulses of the radial force, the series having a first duration, the passive mode having a second duration, wherein an activation cycle is defined by the series of pulses followed by the second duration.
