Reusable analyte sensor site and method of using the same

A system for measuring analyte in a body of a user, the system comprising:

• a replaceable analyte sensor for determining a level of an analyte;
• and
• a reusable analyte sensor site made from a site housing material formed to have an interior cavity with an opening and a conduit that is connected to the opening of the interior cavity to provide access to the interior cavity, wherein the site housing material is selected to promote tissue ingrowth and vasuclarization and be free of tissue ingress, wherein the site housing material permits the analyte to pass through the site housing material to the interior cavity to permit measurement by the replaceable analyte sensor, and wherein the conduit has a predetermined length to inhibit trauma and encapsulation of tissue occurring at the conduit, and associated with placing the replaceable analyte sensor in the interior cavity of the site housing, from interfering with the tissue ingrowth and vascularization surrounding the interior cavity of the site housing material.

A reusable infusion site for use with a replaceable infusion catheter for infusion a fluid into the body of a user, the site comprising:

• a site housing material formed to have an interior cavity with an opening and a conduit that is connected to the opening of the interior cavity to provide access to the interior cavity, wherein the site housing material is selected to promote tissue ingrowth and vasuclarization and be free of tissue ingress, wherein the site housing material permits the fluid to pass out through the site housing material from the interior cavity to deliver the fluid to the body of the user, and wherein the conduit has a predetermined length to prevent trauma and encapsulation of tissue occurring at the conduit, and associated with placing the replaceable infusion catheter in the interior cavity of the site housing, from interfering with the tissue ingrowth and vascularization surrounding the interior cavity of the site housing material.
