What is claimed is: 1. A device for subcutaneous monitoring of glucose levels, comprising: a housing; a sensor; and a porous biointerface layer for promoting long term microcirculatory delivery of glucose and oxygen to the sensor for a time period of at least about one month, wherein the porous biointerface layer comprises an architecture that supports tissue ingrowth and is configured to maintain sufficient fluid flow to the sensor for long term glucose measurement, wherein the porous biointerface layer further comprises a first bioactive agent configured to be released over a first time period of from about one day to about one month, wherein release of the first bioactive agent is configured to increase a rate at which the device becomes functional by at least partially overcoming sleep period effects associated with a temporary decrease in sensor sensitivity associated with tissue ingrowth into the porous biointerface layer; wherein the porous biointerface layer further comprises a second bioactive agent configured to be released over a second time period, wherein release of the second bioactive a ent is configured to modulate a foreign body response to reduce a continual decline in sensor sensitivity over a life of a sensor. 2. The device of claim 1, wherein the biointerface layer comprises a material selected from the group consisting of hydrophilic polyvinylidene fluoride, mixed cellulose esters, polyvinyl chloride, polyvinyl alcohol, polyethylene, polytetrafluoroethylene, cellulose acetate, cellulose nitrate, polycarbonate, nylon, polyester, mixed esters of cellulose polyvinylidene difluoride, silicone, polyacrylonitrile, polypropylene, polysulfone, polymethacrylate, and mixtures thereof. 3.
