Internal sensors for use with gastric restriction devices
First Claim
Patent Images
1. A system for use in controlling food intake in a patient, the system comprising:
- a gastric restriction device that engages the patient'"'"'s stomach between proximal and distal gastric regions that are connected by a stomal opening; and
a sensor coupled to the gastric restriction device;
wherein the sensor is configured to reside within the patient'"'"'s body when the gastric restriction device is engaged with the stomach; and
wherein the sensor outputs information indicative of at least one of;
a presence of a test substance within the stomach;
a movement of the test substance within the stomach;
a movement of the gastric restriction device from a first position to a second position; and
an erosion of a wall of the stomach.

Abstract
Apparatus and methods of monitoring gastric restriction devices are described. Internally mounted sensors detect at least one of a quantity of a test substance, a flow through the stomal opening produced by a restriction device, slippage of the device, and erosion of the gastric wall. In some embodiments flow versus no flow can be determined, or a flow rate can be calculated. Monitoring of internally mounted sensors permits optimization of the performance of a gastric restriction device, using noninvasive techniques.

66. A system for use in controlling food intake in a patient, the system comprising:
-
means for engaging the patient'"'"'s stomach between proximal and distal gastric regions that are connected by a stomal opening; and means for sensing coupled to the means for engaging; wherein the means for sensing is configured to reside within the patient'"'"'s body when the means for engaging is engaged with the stomach; and wherein the means for sensing outputs information indicative of at least one of a presence of a test substance within the stomach, a movement of a test substance within the stomach, a movement of the gastric restriction device from a first position to a second position, and a presence of an erosion of a wall of the stomach.
