Subcutaneous sensor inserter and method
First Claim
1. A continuous analyte monitoring inserter apparatus for subcutaneous placement of a sensor into skin of a patient that minimizes pain to a patient, the apparatus comprising:
- a single action inserter assembly having a housing body with a first body end and a second body end, a deployment button partially disposed and slidable within the housing body through the first body end, the deployment button being movable between a first position and a second position, and a sensor housing partially disposed within and removably retained in the second body end;
a needle having a cross-sectional shape that minimizes a peak force of insertion into the skin of the patient wherein the needle is movably disposed within the single action inserter assembly; and
an implantable sensor partially disposed within the needle,wherein the inserter assembly is adapted to substantially simultaneously implant the sensor subcutaneously into the patient, retract the needle, fix the sensor within the sensor housing and release the inserter assembly from the sensor housing with a single activation of the deployment button caused by moving the deployment button from the first position to the second position while minimizing pain to the patient.

Abstract
An inserter assembly for continuous glucose monitoring with medication delivery capability where the assembly has a deployment button containing a needle deployment mechanism having a sharp held in a pre-release position, a housing body in which the deployment button is movably received within a top end of the housing body, the housing body having a sensor deployment assembly containing a lumen and a sensor disposed within the lumen and extending out of the lumen to a circuit board that is part of the sensor deployment assembly, the sensor deployment assembly matingly connected to the sharp where the sharp extends beyond the sensor deployment assembly and contains the sensor not fixedly attached to the sharp, and a sensor housing releasably received within a lower end of the housing body, the sharp extending into a sensor deployment assembly recess within the sensor housing and directly above a sensor opening in a bottom of the sensor housing.

- 6. A single action inserter assembly for subcutaneous placement of a sensor into a patient that minimizes pain to the patient wherein the inserter assembly is adapted to substantially simultaneously using a single action perform the following steps of (1) implanting the sensor subcutaneously into the patient, (2) fixedly seating a sensor deployment assembly that includes the sensor within a sensor housing adhesively attached to the patient, (3) retracting a needle used to implant the sensor, the needle having a cross-sectional shape that minimizes a peak force of insertion into the skin of the patient, and (4) releasing the inserter assembly from the sensor housing.
- 11. A single action inserter assembly for subcutaneous placement of a sensor into a patient that minimizes pain to the patient wherein a single operation of the inserter assembly by an inserter assembly user is adapted to perform substantially simultaneously the following steps of (1) implanting the sensor subcutaneously into the patient, (2) fixedly seating a sensor deployment assembly that includes the sensor within a sensor housing attached to the patient, (3) retracting a needle used to implant the sensor into the inserter assembly, the needle having a cross-sectional shape that minimizes a peak force of insertion into the skin of the patient, and (4) releasing the inserter assembly from the sensor housing.

16. A method of minimizing pain when inserting an in-vivo analyte sensor subcutaneously for continuous analyte monitoring of a patient, the method comprising:
-
providing a single action inserter assembly having a needle with a cross-sectional shape that minimizes a peak force of insertion into the skin of the patient, an implantable sensor, a deployment button for implanting the implantable sensor using the needle and for retracting the needle, and a sensor housing for retaining the implanted sensor in an implanted orientation once deployed by the deployment button; and using a single action to activate the deployment button of the single action inserter assembly that causes the following actions to substantially simultaneously occur;
(1) implanting the sensor subcutaneously into the patient, (2) fixedly seating the sensor within the sensor housing attached to the patient, (3) retracting the needle used to implant the sensor into the inserter assembly, and (4) releasing the inserter assembly from the sensor housing,wherein the needle and the single action minimizes pain when inserting the sensor subcutaneously. - View Dependent Claims (17, 18, 19, 20)
