Claims

A continuous analyte monitoring inserter device comprising:
an outer member;
an inner member configured to slide axially within the outer member;
a transmitter carrier configured to support the transmitter and biosensor assembly and including a bias member;
an insertion device;
a pivot member configured to pivot relative to the transmitter carrier to support the insertion device;
axial movement of the outer member is configured to urge the biasing member against the pivot member;
a force applied to the outer member over a first portion of stroke causes the pivot member to impart axial movement to the transmitter carrier and the insertion device;
over a second portion of the stroke, the biasing member causes pivoting movement of the pivot member, and the pivoting movement of the pivot member retracts the insertion device;
the outer member has a first pivot window and the inner member has a second pivot window;
At least a portion of the pivotal movement of the pivot member moves through the first pivot window of the outer member such that the end of the pivot member enters the first pivot window through the second pivot window. overlaps the second pivot window of the inner member .

The outer member includes a first alignment element, the inner member includes a second alignment element, and the first alignment element joins the second alignment element to form the outer member. 2. The continuous analyte monitoring inserter device of claim 1 , configured for vertical alignment of the first pivot window with the second pivot window of the inner member.

The biasing member is flexible and has a locking element that engages the second pivot window of the inner member to limit movement of the biasing member and the pivoting member after biosensor insertion. 2. The continuous analyte monitoring inserter device of claim 1 , comprising:

over the first portion of the stroke until the pivot member enters the second pivot window of the inner member such that axial movement of the pivot member facilitates insertion of a biosensor; 2. The continuous analyte monitoring inserter device of Claim 1, wherein said pivot member is prevented from pivoting .

2. The continuous analyte monitoring inserter device of claim 1, wherein the transmitter carrier is configured to support the transmitter and biosensor assembly during insertion of the biosensor of the transmitter and biosensor assembly. .

The pivot member is
an insertion device support element configured to support the insertion device during insertion ;
a bias member interface element configured to interface with the bias member;
with
2. The continuous analyte monitoring inserter device of claim 1, wherein the biasing member is curved within the continuous analyte monitoring inserter device .

7. The continuous analyte monitoring inserter device of Claim 6 , wherein the biasing member contacts the inner member, the outer member, and the pivot member during insertion.

4. The inner member includes a pre-insertion locking element extending into the first pivot window of the outer member and configured to prevent the outer member from sliding over the inner member prior to insertion. The continuous analyte monitoring inserter device according to 1.

The inner member includes one or more retainer tangs that extend locally inward to retain the transmitter and biosensor assembly, and the outer member defines one or more local relief openings. wherein said inner member comprises one or more localized contact elements, said one or more localized contact elements capable of fitting into said one or more localized relief openings, thereby: 2. The continuous analyte monitoring inserter device of claim 1 , wherein said one or more retainer tongues can be released away from said transmitter and biosensor assembly .
