METHOD AND APPARATUS FOR INSERTION OF A SENSOR USING AN INTRODUCER
First Claim
1. An insertion device comprising:
- a housing having an opening and adapted to be placed in proximity to animal skin;
an analyte sensor guidance structure disposed inside the housing, said guidance structure adapted to allow passage of an analyte sensor through the guidance structure and through the opening of the housing upon application of a motive force to the analyte sensor; and
an introducer situated at least partially in the housing, said introducer adapted to be in communication with an actuator device, said introducer positioned to partially pass a predetermined distance through the opening of the housing upon application of motive force to the introducer by the actuator device, said introducer adapted to cause, upon application of the motive force, a skin puncture through which the analyte sensor can be inserted.

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, animal skin. Such a device utilizes an introducer device such as a needle or trocar to puncture skin and allow a sensor to enter through the resultant skin puncture. A device in accordance with embodiments of the present invention includes a housing for mounting to animal skin including an opening for receiving both the distal end of an analyte sensor and the end of an introducer, an actuator device for forcing the introducer from a first position within the housing, through the exit port to a second position, with sufficient force to puncture skin.
