Abstract
A reusable analyte sensor site for use with a replaceable analyte sensor for determining a level of an analyte includes a site housing and a resealable insertion site coupled to one end of the site housing. Preferably, the site housing is formed to have an interior cavity, and includes an outer membrane made of a material selected to promote vascularization and having a first pore size, and an inner membrane made of a material selected to be free of tissue ingress. Also, the site housing permits the analyte to pass through the site housing to the interior cavity to permit measurement by the replaceable analyte sensor. The resealable insertion site is provided for inserting the replaceable analyte sensor into the interior cavity of the site housing.
