Abstract
Systems are disclosed which utilize implanted glucose sensitive living cells to monitor blood glucose levels. The implanted cells produce a detectable electrical or optical signal in response to changes in glucose concentration in surrounding tissue. The signal is then detected and interpreted to give a reading indicative of blood glucose levels. Capsules containing glucose sensitive cells and electrodes for detecting electrical activity are also disclosed. Methods of monitoring blood glucose are also described utilizing the systems and capsules disclosed.
Claims25
A system for monitoring glucose levels in a patient's body tissues, said system comprising:
- implantable glucose sensitive living animal cells capable of producing an electrical or optical signal in response to the glucose concentration in the medium surrounding said cells in the patient;
- and
- means for detecting said electrical or optical signal.
A method of monitoring the glucose level of a patient, said method comprising:
- implanting into said patient glucose sensitive living animal cells capable of producing an electrical or optical signal in response to glucose concentration in the medium surrounding said cells in the patient;
- detecting said signal;
- and
- correlating said signal with said glucose concentration.
A method of administering a dosage of insulin, said method comprising:
- implanting into said patient glucose sensitive living animal cells capable of producing a signal in response to glucose concentration in the medium surrounding said cells;
- detecting said signal;
- correlating said signal with said glucose concentration;
- and
- administering said dosage of insulin at a level appropriate to said glucose concentration.
