Analyte sensor

A method for distributing and controlling use of an implantable sensor system comprising reusable and single-use parts, the method comprising:

• providing a single-use device associated with the sensor system;
• providing information associated with the single-use device;
• determining information indicative of sensor insertion into a host's tissue or information indicative of sensor removal from the host's tissue;
• and
• providing a reusable device associated with a sensor system, wherein the reusable device is configured to provide sensor information responsive to receipt of the information associated with the single-use device, wherein the single-use device comprises an analyte sensor, and wherein the information associated with the single-use device comprises sensor insertion information configured to enable the sensor system to control a number of sensor insertions by using a number of sensor initializations or a number of iterations of sensor duration.
