Abstract

A transcutaneous, implantable skin port sensor includes an access component and a sensor component, both of which can be made from inexpensive biocompatible materials. The access component provides a biological seal that forms around the skin port sensor. The sensor component facilitates non-invasive optically based measurement of analytes by providing a window to the body which avoids changes in the optical signal due to variations in skin optics, optical pathlength, ambient temperature and probe pressure. Tissue ingrowth or interstitial fluid in a through portion downstream of the optical window serves as the sample for the non-invasive, optically based measurement.
