Abstract
An apparatus for insertion of a medical device in the skin of a subject is provided, as well as methods of inserting medical devices.
Claims28
A method of inserting an analyte sensor into a subject, the method comprising:
- positioning a distal surface of an insertion assembly on skin of the subject such that an adhesive layer adheres to the skin, the insertion assembly comprising a spring in a loaded position and an interior;
- and
- pressing a button of the insertion assembly in a first lateral direction toward the interior of the insertion assembly,
- wherein pressing the button releases the spring from the loaded position such that the spring moves a sliding member lengthwise along a length of a track in the insertion assembly, wherein the length of the track is oriented in a second lateral direction different from the first lateral direction,
- wherein movement of the sliding member along the length of the track causes an actuator to advance in a distal longitudinal direction, wherein advancement of the actuator causes advancement of a sharp and the analyte sensor in the distal longitudinal direction,
- wherein the sliding member applies a force on the actuator in a proximal longitudinal direction after the sharp and the analyte sensor have been advanced in the distal longitudinal direction, and
- wherein the distal longitudinal direction and the proximal longitudinal direction are defined along an insertion axis.

An insertion assembly for inserting an analyte sensor into a subject, the insertion assembly comprising:
- a distal surface including an adhesive layer, wherein the distal surface is configured to be positioned on skin of the subject such that the adhesive layer adheres to the skin;
- an interior of the insertion assembly including a spring, a sliding member, an actuator, and a track;
- and
- a button configured to be pressed in a first lateral direction toward the interior of the insertion assembly,
- wherein the button is further configured to release the spring from a loaded position upon being pressed, such that the spring moves the sliding member lengthwise along a length of the track,
- wherein the length of the track is oriented in a second lateral direction different from the first lateral direction,
- wherein the sliding member is configured to move along the length of the track and cause the actuator to advance in a distal longitudinal direction, wherein advancement of the actuator causes advancement of a sharp and the analyte sensor in the distal longitudinal direction,
- wherein the sliding member is further configured to apply a force on the actuator in a proximal longitudinal direction after the sharp and the analyte sensor have been advanced in the distal longitudinal direction, and
- wherein the distal longitudinal direction and the proximal longitudinal direction are defined along an insertion axis.
