Abstract
A device for continuously monitoring glucose levels in a patient includes a lead assembly in electrical communication with an electronics assembly. The electronics assembly is configured to be positioned in the subcutaneous tissue and the lead assembly is configured to be positioned in a vessel of the patient, such as in a vein or in an epidural space. The lead assembly has a lumen, and includes at least one electrode in electrical communication with the electronics assembly.
Claims30
A glucose sensor adapted to be at least partially positioned within a vessel in a biological host, comprising:
- a lead assembly comprising a lead that includes at least one electrode having a surface area of at least 5 mm2, wherein a portion of the lead is configured to be positioned within the vessel, wherein said portion has a length that is less than 15 cm, and wherein the lead assembly is configured to generate a current;
- and
- an electronics assembly connected to an end of the lead assembly, positioned at a distance of at least 5 cm from the at least one electrode, wherein the electronics assembly is in electrical communication with the at least one electrode and adapted to receive the current, wherein the electronics assembly comprises a potentiostat in electrical communication with the lead, and wherein the potentiostat is configured to apply a bias potential to the at least one electrode, to receive the current via the lead, and to convert the current into an analog voltage signal.
A method of sensing a glucose level of a biological host using a glucose sensor adapted to be at least partially positioned within a vessel in the biological host, comprising:
- generating a current using a lead assembly comprising a lead that includes at least one electrode having a surface area of at least 5 mm2, wherein a portion of the lead is configured to be positioned within the vessel, and wherein said portion has a length that is less than 15 centimeters;
- and
- processing the current using an electronics assembly connected to an end of the lead assembly, positioned at a distance of at least 5 cm from the at least one electrode, wherein the electronics assembly is in electrical communication with the at least one electrode and adapted to receive the current, wherein the electronics assembly comprises a potentiostat in electrical communication with the lead, and wherein the potentiostat is configured to apply a bias potential to the at least one electrode, to receive the current via the lead, and to convert the current into an analog voltage signal.
