초록 ▼

There is provided an implantable system and method for monitoring pancreatic beta cell electrical activity in a patient in order to obtain a measure of a patient's insulin demand and blood glucose level. A stimulus generator is controlled to deliver stimulus pulses so as to synchronize pancreatic beta cell depolarization, thereby producing an enhanced electrical signal which is sensed and processed. In a specific embodiment, the signal is processed to determine the start and end of beta cell depolarization, from which the depolarization duration is obtained. In order to reduce cardiac interference, each stimulus pulse is timed to be offset from the QRS signal which can interfere with the pancreas sensing. Additionally, the beta cell signals are processed by a correction circuit, e.g., an adaptive filter, to remove QRS artifacts, as well as artifacts from other sources, such as respiration. The thus obtained insulin demand signal is used either to control delivery of insulin from an implanted insulin pump, or to control ongoing pancreatic stimulation of a form to enhance insulin production.

대표청구항 ▼

[ What is claimed is:] [1.]1. A method of obtaining a measure of blood glucose in a patient, comprising:(a) delivering at least one stimulus pulse to a location of said patient containing pancreatic beta cells;(b) sensing the electrical response of said pancreatic beta cells to said stimulus pulse and obtaining a signal representative of said response; and(c) processing said at least one signal and deriving therefrom a measure of patient blood glucose level.
