METHOD AND APPARATUS FOR INSERTION OF A SENSOR
First Claim
1. An insertion device comprising:
- a guidance structure adapted to provide axial support to an analyte sensor, the guidance structure having an exit port; and
an injection activation device associated with the guidance structure, said injection activation device having;
a mechanism adapted to apply a high speed motive force to the analyte sensor such that, when such force is applied, the sensor moves at least partially through the guidance structure and at least partially passes through the exit port.

Abstract
A device and method for delivering a device such as a sensor or fluid transport structure or a fluid transport structure sensor combination into, for example, mammalian skin. Such a device allows a sensor to penetrate mammalian skin without the use of an introducer device such as a needle. A device in accordance with embodiments of the present invention includes a housing for attachment to mammalian skin including an exit port for receiving the distal end of a biosensor and an injection activation device including a mechanism for forcing the sensing device from a first position within the housing, through the exit port to a second position, with sufficiently high velocity to partially penetrate the mammalian skin.
