OBESITY THERAPY AND HEART RATE VARIABILITY
First Claim
Patent Images
1. A medical system, comprising:
- a sensor configured to be positioned in contact with a tissue of a patient to gather data, the gathered data including at least one of pH levels in a stomach of the patient and a heart rate of the patient;
a processor configured to be in communication with the sensor and to analyze the sensed data to determine onset of solid food ingestion by the patient; and
a delivery device configured to be implanted within the patient and to be in communication with the processor, the delivery device being defaulted to a dormant mode in which the delivery device does not deliver an obesity therapy to the patient, and the delivery device being configured to change from the dormant mode to a delivery mode, in which the delivery device delivers the obesity therapy to the patient, in response to the processor determining onset of the solid food ingestion,wherein the obesity therapy comprises electrical stimulation of the patient and administration of a chemical to the patient.

Abstract
Methods and devices are provided for delivering obesity therapy to a patient. In general, the methods and devices allow for onset of a patient eating solid food, e.g., the patient beginning a meal, to trigger delivery of an obesity therapy to a patient. The obesity therapy can be delivered to the patient for a limited period of time such that the patient stops receiving the obesity therapy prior to a second onset of the patient eating solid food, e.g., the patient beginning a second meal, which can trigger a second delivery of the obesity therapy to the patient for a limited period of time.

14. A medical method, comprising:
-
determining an onset of solid food ingestion by a patient by detecting a change in heart rate of the patient and a change in a pH level in a stomach of the patient; and in response to the detection of the change in heart rate and the change in the pH level, starting delivery of an obesity therapy to the patient, wherein the obesity therapy includes electrical stimulation of a tissue of the patient and administration of a chemical to the patient. - View Dependent Claims (15, 16, 17, 18)

19. A computer readable medium having a program stored thereon, wherein the program causes a computer to perform the steps of:
-
determining an onset of solid food ingestion by a patient by detecting a change in heart rate of the patient and a change in a pH level in a stomach of the patient; and in response to the detection of the change in heart rate and the change in the pH level, starting delivery of an obesity therapy to the patient, wherein the obesity therapy includes electrical stimulation of a tissue of the patient and administration of a chemical to the patient.
