Abstract
An apparatus for sensing multiple parameters includes an implantable housing and a plurality of implantable sensors disposed within the implantable housing. The plurality of implantable sensors sense parameters in a patient, such as biological or physiological parameters, for example, and each responds to an analyte in the patient. The plurality of implantable sensors may include, but is not limited to, electrochemical, potentiometric, current and optical sensors.
Claims24
An apparatus for sensing multiple parameters comprising:
- an implantable housing;
- an implantable tip affixed to a first end of the housing;
- a plurality of implantable sensors with sensing elements disposed within the implantable housing for sensing a plurality of different parameters in a patient;
- each sensor has a first surface on which the sensing element is disposed, the first surface extends along a plane;
- each sensor is arranged such that the plane in which the first surface of a sensor extends intersects with the plane in which the first surface of an adjacent sensor extends;
- and
- each sensor for detecting a different type of molecule relative to at least one other sensor in the plurality of implantable sensors.
An apparatus for sensing multiple parameters comprising:
- an implantable housing;
- an implantable tip affixed to a first end of the housing;
- a plurality of implantable sensors disposed within the implantable housing for sensing a plurality of different parameters in a patient;
- each sensor comprising a plurality of sensing elements, the plurality of sensing elements disposed on a single sensor, each sensing element configured to detect a different type of molecule relative to at least one other sensing element in the plurality of sensing elements and
- wherein at least one of the plurality of sensing elements is configured to use lactate oxidase enzyme that responds to lactate;
- wherein the plurality of sensing elements further comprise an oxygen sensing element and a glucose sensing element wherein the plurality of sensing elements are operatively coupled to a single potentiostat to differentially and individually interrogate oxygen, glucose and lactate.
