A biocompatible, human implantable apparatus and a method for fully encasing a circuit within a polymer housing. The method may include placing the circuit in a mold, injecting a formulation into the mold, and polymerizing the formulation. The formulation may include monomers and polymers. The apparatus may include a circuit in a polymerized formulation of monomers and polymers.

Biocompatible, human implantable apparatus and method for fully encasing a circuit within a polymer housing

The present invention provides an insertion device and method for implanting a biosensor into a patient subject. In one embodiment, a biosensor is stored in the instrument's hydration chamber which enables the biosensor to maintain proper hydration and sterilization prior to insertion. The instrument further includes a plunger that travels along a channel within the support device. After the biosensor is placed into the channel, the user pushes the plunger causing the biosensor to move through the channel and a hollow tube and into the patient subject. The present invention also provides for packaging and storing a biosensor and insertion device so that the biosensor is hydrated and sterile prior to insertion.

The present invention provides systems and methods for attenuating the effect of ambient light on optical sensors and for measuring and compensating quantitatively for the ambient light.

System and method for attenuating the effect of ambient light on an optical sensor

An optical sensor device for determining the presence or concentration of an analyte, contains a waveguide disposed over a light source and a light detector mounted on a surface of a substrate and separated by an internal baffle, wherein the waveguide has a thickness corresponding to a far field emission point of the light source as determined by a light shielding baffle between the light source and light detector. An analyte indicator matrix is disposed on the outer surface of the waveguide. The sensor device geometry takes advantage of only direct illumination of the indicator matrix, and direct collection of indicator matrix illumination, without any significant reflection by said waveguide. Undesirable light noise generated by the light source passes directly out of the device through the waveguide.
