Abstract
A transcutaneous implant having a stable biological seal at the skin interface, obviating the need for puncturing the skin to obtain fluid samples is described. The implant includes an advanced filtration membrane to promote neovascularization which eliminates mass transfer problems by promoting the development of capillary networks with transcapillary mass transfer rates high enough to insure rapid exchange of analyte between blood and the device. Additionally the membrane provides a bioprotective layer which prevents transport of proteins and cellular components into the device.
