Inserter for in-vitro analyte sensor
First Claim
1. A device for implanting an analyte sensor into a subcutaneous fat layer, the device comprising:
- a housing positioned above the subcutaneous fat layer;
a blade shuttle comprising a first end, wherein the blade shuttle comprises a piercing needle at the first end of the blade shuttle; and
a sensor shuttle comprising a first end, wherein the analyte sensor is positioned at the first end of the sensor shuttle;
wherein the first end of blade shuttle rotates towards and pierces the subcutaneous fat layer with the piercing needle to create an incision and wherein the first end of the sensor shuttle follows the first end of the blade shuttle into the incision implanting the analyte sensor in the subcutaneous fat layer.

Abstract
A device and method for implanting an analyte sensor into a subcutaneous fat layer is presented. The device comprises a housing that is positioned above the subcutaneous fat layer, a blade shuttle, and a sensor shuttle. In one embodiment, a spring is compressed between the blade shuttle and the sensor shuttle. The blade shuttle and sensor shuttle move towards the subcutaneous fat layer. When a spring force is released by the spring, the blade shuttle moves towards and pierces into the subcutaneous fat layer creating a pathway into the subcutaneous fat layer. The analyte sensor is implanted by the sensor shuttle by following the blade shuttle into the pathway created by the blade shuttle. The blade shuttle is then retracted from the subcutaneous fat layer, leaving the analyte sensor in the fat layer.

19. A device for implanting an analyte sensor into a subcutaneous fat layer, the device comprising:
-
a substantially flat housing comprised of a upper housing, a lower housing and a base plate, wherein the substantially flat housing is positioned above the subcutaneous fat layer; a blade shuttle positioned within the lower housing, wherein the blade shuttle comprises a needle at one end of the blade shuttle; and a sensor shuttle positioned within the lower housing, wherein the analyte sensor is positioned at one end of the sensor shuttle; and a rotatable cam positioned between and engaged with the blade shuttle and the sensor shuttle; wherein the rotation of the cam results in the needle of the blade shuttle piercing the subcutaneous fat layer to create an incision, followed by the sensor shuttle implanting the analyte sensor in the incision the subcutaneous fat layer. - View Dependent Claims (20, 21, 22, 23)
